-Subject: MIPS: Rewrite <asm/div64.h> to work with gcc 4.4.0.
-X-Git-Url: http://www.linux-mips.org/git?p=linux.git;a=commitdiff_plain;h=a1b68289997030df64cba8478d5767fe10e42a58
-
-MIPS: Rewrite <asm/div64.h> to work with gcc 4.4.0.
-
-The inline assembler used on 32-bit kernels was using the "h" constraint
-which was considered dangerous and removed for gcc 4.4.0.

-From: Wu Zhangjin <wuzj@lemote.com>
-
-the gcc 4.4 support for MIPS mostly refer to this PATCH:
-http://www.nabble.com/-PATCH--MIPS:-Handle-removal-of-%27h%27-constraint-in-GCC-4.4-td22192768.html
-but have been tuned a little.
-
-because only gcc 4.4 have loongson-specific support, so, we need to
-choose the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and
-we also need to consider use -march=loongson2e and -march=loongson2f for
-loongson2e and loongson2f respectively. this is handled by adding two
-new kernel options: CPU_LOONGSON2E and CPU_LOONGSON2F(thanks for the
-solutin provided by ZhangLe).
-
-I have tested it on FuLoong(2f) in 32bit and 64bit with gcc-4.4 and
-gcc-4.3. so, basically, it works.

-Subject: [PATCH] MIPS: fix loading of modules with unresolved weak symbols
-
-Loading of modules with unresolved weak symbols fails on MIPS
-since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.
-
-Modules: handle symbols that have a zero value
-
-The module subsystem cannot handle symbols that are zero.  If symbols
-are present that have a zero value then the module resolver prints out a
-message that these symbols are unresolved.
-
-We have to use IS_ERR_VALUE() to check that a symbol has been resolved
-or not.

-+ *              - Fix "Dead-loop on netdevice imq"-issue
-+ *             Marcel Sebek <sebek64@post.cz>
-+ *              - Update to 2.6.2-rc1
-+ *
-+ *	       After some time of inactivity there is a group taking care
-+ *	       of IMQ again: http://www.linuximq.net
-+ *
-+ *
-+ *	       2004/06/30 - New version of IMQ patch to kernels <=2.6.7
-+ *             including the following changes:
-+ *
-+ *	       - Correction of ipv6 support "+"s issue (Hasso Tepper)
-+ *	       - Correction of imq_init_devs() issue that resulted in
-+ *	       kernel OOPS unloading IMQ as module (Norbert Buchmuller)
-+ *	       - Addition of functionality to choose number of IMQ devices
-+ *	       during kernel config (Andre Correa)
-+ *	       - Addition of functionality to choose how IMQ hooks on
-+ *	       PRE and POSTROUTING (after or before NAT) (Andre Correa)
-+ *	       - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
-+ *
-+ *
-+ *             2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
-+ *             released with almost no problems. 2.6.14-x was released
-+ *             with some important changes: nfcache was removed; After
-+ *             some weeks of trouble we figured out that some IMQ fields
-+ *             in skb were missing in skbuff.c - skb_clone and copy_skb_header.
-+ *             These functions are correctly patched by this new patch version.
-+ *
-+ *             Thanks for all who helped to figure out all the problems with
-+ *             2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
-+ *             Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
-+ *             I didn't forget anybody). I apologize again for my lack of time.
-+ *
-+ *
-+ *             2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
-+ *             of qdisc_restart() and moved qdisc_run() to tasklet to avoid
-+ *             recursive locking. New initialization routines to fix 'rmmod' not
-+ *             working anymore. Used code from ifb.c. (Jussi Kivilinna)
-+ *
-+ *             2008/08/06 - 2.6.26 - (JK)
-+ *              - Replaced tasklet with 'netif_schedule()'.
-+ *              - Cleaned up and added comments for imq_nf_queue().
-+ *
-+ *             2009/04/12
-+ *              - Add skb_save_cb/skb_restore_cb helper functions for backuping
-+ *                control buffer. This is needed because qdisc-layer on kernels
-+ *                2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
-+ *              - Add better locking for IMQ device. Hopefully this will solve
-+ *                SMP issues. (Jussi Kivilinna)
-+ *              - Port to 2.6.27
-+ *              - Port to 2.6.28
-+ *              - Port to 2.6.29 + fix rmmod not working
-+ *
-+ *             2009/04/20 - (Jussi Kivilinna)
-+ *              - Use netdevice feature flags to avoid extra packet handling
-+ *                by core networking layer and possibly increase performance.
-+ *
-+ *	       Also, many thanks to pablo Sebastian Greco for making the initial
-+ *	       patch and to those who helped the testing.
-+ *
-+ *             More info at: http://www.linuximq.net/ (Andre Correa)

-+
-+2006-01-24  Ed L. Cashin <ecashin@coraid.com>
-+

-+
-+2005-10-15  Markus Klotzbuecher  <mk@localhost.localdomain>
-+
-+	* Bugfix for a serious memory leak in mini_fo_follow_link.
-+
-+2005-09-21  Markus Klotzbuecher  <mk@mary>
-+
-+	* new release 0.6.1
-+
-+	* fix of a compiler warning due to changes in 2.6.13
-+
-+2005-09-21  Klaus Wenninger  <klaus.wenninger@siemens.com>
-+
-+	* file.c: readdir: fix for a bug that caused directory entries
-+          to show up twice when using storage filesystems such as
-+          minixfs or pramfs.
-+
-+2005-06-30  Eric Lammerts <eric@lammerts.org>
-+
-+	* fix for an oops when overwriting a binary thats beeing
-+          executed.
-+
-+2005-06-09    <mk@mary>
-+
-+	* Renamed overlay to mini_fo-overlay.
-+
-+	* Added mini_fo-merge script to allow merging of storage and base
-+	after making modifications.
-+
-+2005-05-22  root  <mk@mary>
-+
-+	* Added overlay script that allows to easily mount mini_fo ontop
-+	of a given base directory
-+
-+2005-05-10    <mk@mary>
-+
-+	* inode.c: xattr functions return -EOPNOSUPP instead of
-+          -ENOSUPP, what confuses "ls -l"
-+
-+	* Changed license from LGPL to GPL.
-+
-+2005-05-08  root  <mk@mary>
-+
-+	* Makefile: clean it up and added make install and make
-+          uninstall.
-+
-+2005-05-06    <mk@mary>
-+
-+	* merged devel branch back to main. [v0-6-0-pre3]
-+
-+	* removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+	* ioctl: removed fist_ioctl stuff, that is not needed for
-+          now.
-+
-+2005-05-03    <mk@mary>
-+
-+	* file.c: simplified mini_fo_open and mini_fo_setattr using
-+          new state changing functions. [devel-0-0-17]
-+
-+	* inode.c: Fixed getattr state bug (see below) in 2.4 function
-+          mini_fo_inode revalidate.
-+
-+	* inode.c: found an other bug in mini_fo_getattr. States are not
-+	  reliable in this function, as a file can be opened, unlinked and
-+	  the getattr function called. This results in a deleted dentry
-+	  with an inode. Fix is to ignore states and simply use the inode
-+	  available.
-+
-+2005-04-29    <mk@mary>
-+
-+	* file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+	* file.c: do not use mini_fo_lock so the generic version is
-+          used (I guess).
-+
-+	* inode.c: getattr, never call getattr on lower files, as this
-+          will cause the inum to change.
-+
-+	* inode.c: rename_reg_file renamed to rename_nondir, as it
-+          doesn't matter as long it't not a dir. Removed all
-+          rename_dev_file etc.
-+
-+	* tagged as devel-0-0-15
-+
-+	* inode.c: added support for chosing support for extended
-+          attrs at compile time by XATTR define in mini_fo.h .
-+
-+	* inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+          lower again, what avoids inode number changes that confused
-+          rm again. This is the proper solution.
-+
-+2005-04-24    <mk@mary>
-+
-+	* all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+	* inode.c: fixed mini_fo_getattr to not change the inode
-+          number, even if lower files change.
-+
-+	* super.c: fixed a bug that caused deleted base file to show
-+          up suddenly after some time, or after creating a special
-+          file. The problem was that after some time or after special
-+          file creating sync_sb_inodes is called by the vfs, that
-+          called our mini_fo_put_inode. There was (wrongly) called
-+          __meta_put_lists, that nuked the lists, although the inode
-+          was going to continue its life. Moving __meta_put_lists to
-+          mini_fo_clear_inode, where an inode is really destroyed,
-+          solved the problem.
-+
-+
-+2005-04-23    <mk@mary>
-+
-+	* state.c, aux.c: more cleaning up and
-+          simplifications. [devel-0-0-13]
-+
-+	* inode.c: implemented mini_fo_getattr, that was required for
-+          2.6 because inode_revalidate has been remove there, and the
-+	  old "du" bug returned.
-+
-+
-+2005-04-20    <mk@mary>
-+
-+	* aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+          in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19    <mk@mary>
-+
-+	* Fixed a bug under 2.6 that caused files deleted via mini_fo
-+          not to be deleted properly and therefore the fs filled up
-+          untill no memory was left. [devel-0-0-12]
-+
-+	* Added basic hard link support. This means that creating
-+          hardlinks will work, but existing ones will be treated as
-+          individual files. [devel-0-0-11]
-+
-+2005-04-17    <mk@mary>
-+
-+	* Bugfixes
-+
-+2005-04-13  root  <mk@mary>
-+
-+	* Added file state.c for the state transition
-+          functions. Doesn't work very well yet, though...
-+
-+2005-04-12    <mk@mary>
-+
-+	* Porting to 2.6 started, which is easier than expected, also
-+          due to Olivier previous work.
-+
-+2005-04-08    <mk@mary>
-+
-+	* Fixed the bug that caused du to return invalid sizes of
-+          directory trees. The problem was that
-+          mini_fo_inode_revalidate didn't always copy the attributes
-+          from the base inode properly.
-+
-+2005-04-01  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Merged devel branch back to main trunk and updated the
-+          RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Fixed some bugs in rename_reg_file, that only showed up in
-+          the kernel compile test. Kernel compiles cleanly ontop of
-+          mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Many, many directory renaming bugfixes and a lot of other
-+          cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Finished implementing lightweight directory renaming. Some
-+          basic testing indicates it works fine.
-+	  Next is to implement testcases for the testsuite and confirm
-+          everything is really working ok.
-+
-+2005-03-18  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Finished implementing meta.c stuff required for directory
-+          renaming.
-+
-+2005-03-17  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Fixed all compile warnings + an extremly old bug that
-+          somehow crept in while reworking the wol stuff to the META
-+          system. Turning on -Werror again... :-)
-+
-+	* Fixed some bugs in the new rename_reg_file function.
-+
-+	* Rewrote mini_fo rename and split it into several
-+          subfunctions, that handle the different types
-+          seperately. Rewrote the regular file function aswell, as it
-+          was implemented somewhat inefficient.
-+
-+2005-03-16  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Implemented new META subsystem, removed old WOL stuff in favor
-+	  if it.
-+
-+	* After some basic testing everything seems ok...
-+
-+2005-03-11  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Renaming a non regular file caused trouble because I always
-+	  tried to copy the contents. Now I only do this for regular
-+	  files. mini_fo_rename still isn't implemented properly, renaming
-+	  of device files, symlinks etc. results in a empty regular file
-+	  instead of the proper type.
-+
-+	* Directory renaming suddenly works! What a surprise! I guess
-+          this is because renaming is implemented as making a copy and
-+          removing the original. Still this might not work
-+          everywhere...
-+
-+2005-03-09  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Bugfix, when a mini_fo directory that exists in storage
-+  	  (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+  	  possibly existing WOL file contained in it needs to be
-+  	  deleted too.
-+
-+	* Starting cleanup: defined state names in order to get rid of
-+          the state numbers.
-+
-+2005-03-08  Markus Klotzbuecher  <mk@chasey>
-+
-+	* Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+	* Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+          DEL_REWRITTEN the hash was calculated from the base dentry,
-+          which was wrong and and caused assertions in
-+          __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21    <mk@mary>
-+
-+	* Implemented directory deleting (inode.c)
-+
-+	* main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22    <mk@mary>
-+
-+	* Makefile cleanup and uml stuff, removed unneccessary files
-+
-+	* Created a new and hopefully more informative README
-+
-+	* CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+	* Fix: owner and group where not correctly copied from base to
-+          storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+	* Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+	* Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+	* Implementation of mini_fo_mknod and mini_fo_rename, support
-+          for device files.

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+    # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+    # make install
-+
-+or uninstall with
-+
-+    # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+   mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+                            <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+    # insmod mini_fo.o for a 2.4 kernel or
-+
-+    # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+    # mkdir /tmp/sto
-+    # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+    # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+    # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+    # cd /tmp/sto
-+    # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.
-+
-+
-+TOOLS
-+-----
-+
-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+    # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Release:	mini_fo-0.6.1 (v0-6-1)
-+Date:		21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+  README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+  existing links in the base file system will be treated as if they
-+  were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+  many vital mini_fo parts such as the old whiteout list code which
-+  has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+  directory is renamed via the mini_fo filesystem this will no longer
-+  result in a complete copy in storage, instead only one empty
-+  directory will be created. All base filed contained in the original
-+  directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+  of many features. This release contains several bugfixes related to
-+  directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+  fact tha that "mv" is smart: if the classic rename doesn't work it
-+  will assume that source and target file are on different fs and will
-+  copy the directory and try to remove the source directory. Until
-+  directory removing wasn't implemented, it would fail to do this and
-+  rollback.
-+  So, directory renaming works for now, but it doesn't yet do what you
-+  would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+  happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.

-Subject: [PATCH 2/3] I2C: at24: add kernel interface for reading/writing EEPROM
-Date: Monday 25 August 2008
-From: Kevin Hilman <khilman@deeprootsystems.com>
-To: davinci-linux-open-source@linux.davincidsp.com
-
-This patch adds an interface by which other kernel code can read/write
-detected EEPROM.
-
-The platform code registers a 'setup' callback with the
-at24_platform_data.  When the at24 driver detects an EEPROM, it fills
-out the read and write functions of at24_iface and calls the setup
-callback.  The platform code can then use the read/write functions in
-the at24_iface struct for reading and writing the EEPROM.
-
-Original idea, review and updates by David Brownell <david-b@pacbell.net>
-
-Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

-+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
-+================================================================
-+
-+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
-+MMC or SD card on GPIO pins.
-+
-+Two interfaces for registering a new MMC/SD card device are provided:
-+A static platform-device based mechanism and a dynamic configfs based interface.
-+
-+
-+Registering devices via platform-device
-+=======================================
-+
-+The platform-device interface is used for registering MMC/SD devices that are
-+part of the hardware platform. This is most useful only for embedded machines
-+with MMC/SD devices statically connected to the platform GPIO bus.
-+
-+The data structures are declared in <linux/mmc/gpiommc.h>.
-+
-+To register a new device, define an instance of struct gpiommc_platform_data.
-+This structure holds any information about how the device is hooked up to the
-+GPIO pins and what hardware modes the device supports. See the docbook-style
-+documentation in the header file for more information on the struct fields.
-+
-+Then allocate a new instance of a platform device by doing:
-+
-+	pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
-+
-+This will allocate the platform device data structures and hook it up to the
-+gpiommc driver.
-+Then add the gpiommc_platform_data to the platform device.
-+
-+	err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
-+
-+You may free the local instance of struct gpiommc_platform_data now. (So the
-+struct may be allocated on the stack, too).
-+Now simply register the platform device.
-+
-+	err = platform_device_add(pdev);
-+
-+Done. The gpiommc probe routine will be invoked now and you should see a kernel
-+log message for the added device.
-+
-+
-+Registering devices via configfs
-+================================
-+
-+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
-+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
-+hardware are a common situation.
-+So we provide a dynamic interface to conveniently handle adding and removing
-+devices from userspace, without the need to recompile the kernel.
-+
-+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
-+the dynamic configuration.
-+
-+To create a new device, it must first be allocated with mkdir.
-+The following command will allocate a device named "my_mmc":
-+	mkdir /config/gpiommc/my_mmc
-+
-+There are several configuration files available in the new
-+/config/gpiommc/my_mmc/ directory:
-+
-+gpio_data_in			= The SPI data-IN GPIO pin number.
-+gpio_data_out			= The SPI data-OUT GPIO pin number.
-+gpio_clock			= The SPI Clock GPIO pin number.
-+gpio_chipselect			= The SPI Chipselect GPIO pin number.
-+gpio_chipselect_activelow	= Boolean. If 0, Chipselect is active-HIGH.
-+				  If 1, Chipselect is active-LOW.
-+spi_mode			= The SPI data mode. Can be 0-3.
-+spi_delay			= Enable all delays in the lowlevel bitbanging.
-+max_bus_speed			= The maximum SPI bus speed. In Hertz.
-+
-+register			= Not a configuration parameter.
-+				  Used to register the configured card
-+				  with the kernel.
-+
-+The device must first get configured and then registered by writing "1" to
-+the "register" file.
-+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
-+and "gpio_chipselect" are essential and _must_ be configured before writing
-+"1" to the "register" file. The registration will fail, otherwise.
-+
-+The default values for the other parameters are:
-+gpio_chipselect_activelow	= 1		(CS active-LOW)
-+spi_mode			= 0		(SPI_MODE_0)
-+spi_delay			= 1		(enabled)
-+max_bus_speed			= 5000000	(5 Mhz)
-+
-+Configuration values can not be changed after registration. To unregister
-+the device, write a "0" to the "register" file. The configuration can be
-+changed again after unregistering.
-+
-+To completely remove the device, simply rmdir the directory
-+(/config/gpiommc/my_mmc in this example).
-+There's no need to first unregister the device before removing it. That will
-+be done automatically.
