* oxnas: add 5.4 as testing kernel versionDaniel Golle2020-03-062-822/+0
| | | | | | | Add 5.4 kernel version as a new testing kernel option. Run-tested on Shuttle KD20, seems to work just as well as kernel 4.14. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* oxnas: move PCIe controller outside of simple-busDaniel Golle2019-03-101-7/+24
| | | | | | | | Move PCIe controller outside down to SoC level to avoid resource mapping problems. Also add more detailed error handling when mapping registers. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* oxnas: pcie: model shared resource as external pcie-phy driverDaniel Golle2019-03-042-67/+164
| | | | | | | Refactor pcie-oxnas to have shared resources in syscon and new pcie-phy driver. Hopefully this revives PCIe... Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* oxnas: bring in new oxnas targetDaniel Golle2018-06-013-0/+3819
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reboot the oxnas target based on Linux 4.14 by rebasing our support on top of the now-existing upstream kernel support. This commit brings oxnas support to the level of v4.17 having upstream drivers for Ethernet, Serial and NAND flash. Botch up OpenWrt's local drivers for EHCI, SATA and PCIe based on the new platform code and device-tree. Re-introduce base-files from old oxnas target which works for now but needs further clean-up towards generic board support. Functional issues: * PCIe won't come up (hence no USB3 on Shuttle KD20) * I2C bus of Akitio myCloud device is likely not to work (missing debounce support in new pinctrl driver) Code-style issues: * plla/pllb needs further cleanup -- currently their users or writing into the syscon regmap after acquireling the clk instead of using defined clk_*_*() functions to setup multipliers and dividors. * PCIe phy needs its own little driver. * SATA driver is a monster and should be split into an mfd having a raidctrl regmap, sata controller, sata ports and sata phy. Tested on MitraStar STG-212 aka. Medion Akoya MD86xxx and Shuttle KD20. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* 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.

| | | | | | | | | | | | | | | | 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
