* oxnas: revert to kernel 4.1Daniel Golle2016-07-184-1/+62
| | | | | | | | | A bug resulting in the NAND not being detected by newer kernels has kept me sleepless for months and yet I wasn't able to discover the cause. Bring back patches and files for 4.1 until this has been resolved. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* oxnas: clean-up NAND driver to fix probing issueJohn Crispin2016-03-101-13/+5
| | | | | | | | | | | A re-write of the driver based on xway_nand.c and constants as well as the cmd_ctrl() function from the original oxnas_nand.c resulted in a extremely similar looking file (see diffsize), and fixes the issue of NAND not being detected on newer kernels.

* oxnas: move gmac soc glue from mach to stmmac driverJohn Crispin2015-10-191-0/+172
| | | | | | | | | Still a lot of kernel-version ifdef'ery, but imho that's easy to remove once obsoleted and avoids duplicate code in the meantime. Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 47218

* oxnas: sata_oxnas: make irq handler more readableFelix Fietkau2014-12-221-12/+13

* oxnas: sata_oxnas: refactoring phase 2Felix Fietkau2014-12-221-112/+175
| | | | | | | | | | | | | - replaced // comments by /* comments */ - added line-breaks where needed - fixed white-space according to kernel style - fixed some obvious spelling mistakes in comments and printks - removed some unneeded left-overs imported from vendor code-base - replaced printk(...) by libata macros where possible Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 43767
* oxnas: sata_oxnas: refactoring phase 1Felix Fietkau2014-12-221-114/+142
| | | | | | | | | | | | | locking for 2nd port and hwraid was added from vendor's GPL code which doesn't comply with current kernel coding style. - moved all global variables into host_priv - renamed locks - sanetized acquire() and release() parameter list Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 43766
* oxnas: add support for 2nd S-ATA port to sata_oxnas driverJohn Crispin2014-12-101-83/+560
| | | | | | | | | | | | | | | | similar to mv_sata, use nr-ports attribute from device tree. import and adapt locking code from vendor GPL sources. add dma controller handling, it may be used in future to avoid full core resets similar to the vendor SDK's "progressive cleanup" function. this is still very dirty and aimed to first of all do things quite exactly like the reference code. and it somehow works. obviously there is lots of room for improvement :) Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 43598

* add new target 'oxnas'John Crispin2014-11-269-0/+5074
This is the oxnas target previously developed at http://gitorious.org/openwrt-oxnas Basically, this consolidates the changes and addtionas from http://github.org/kref/linux-oxnas into a new OpenWrt hardware target 'oxnas' adding support for PLX Technology NAS7820/NAS7821/NAS7825/... formally known as Oxford Semiconductor OXE810SE/OXE815/OX820/... For now there are 4 supported boards: Cloud Engines Pogoplug V3 (without PCIe) fully supported Cloud Engines Pogoplug Pro (with PCIe) fully supported MitraStar STG-212 aka ZyXEL NSA-212, aka Medion Akoya P89625 / P89636 / P89626 / P89630, aka Medion MD 86407 / MD 86805 / MD 86517 / MD 86587 fully supported, see http://wiki.openwrt.org/toh/medion/md86587 Shuttle KD-20 partially supported (S-ATA driver lacks support for 2nd port) Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 43388
