* ath79: move tplinkpart.c parser to patchesAdrian Schmutzler2020-04-241-235/+0
| | | | | | | | | | | | | Between 4.19 and 5.4, mtd parsers have been moved to "parsers" subdirectory. Like for myloader.c in the previous patch, this patch moves tplinkpart.c to the kernel patches, so the code and the kernel includes are at the same location and the path can be adjusted per kernel. While at it, remove some outdated kernel version switches from the C code. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ath79: fix missing return statement in ar934x_nandDavid Bauer2020-03-221-4/+12
| | | | | | | | | | | The reset assert and deassert methods currently miss a return value, leading to a compilation warning. Return the return-value of reset_control_assert and reset_control_deassert to fix these warnings.

* ath79: fix NAND driver compilation for kernel 5.4David Bauer2020-03-221-5/+122
| | | | | | | | | | | | | | | This fixes the compilation of the AR934x NAND controller driver for kernel 5.4 while leaving it untouched for kernel 4.19. This change is currently not run-tested, as i do not have such a device at hand.

* ath79: add AR934x NAND Flash Controller driverMichal Cieslakiewicz2019-10-201-0/+1481
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains updated driver for Atheros NAND Flash Controller written originally by Gabor Juhos for ar71xx (aka 'ar934x-nfc'). ath79 version has adapted to work with kernel 4.19 and Device Tree. It has also been renamed to 'ar934x-nand' to avoid confusion with Near-Field Communication technology. Controller is present on Atheros AR934x SoCs and required for accessing internal flash storage on routers like Netgear WNDR4300. This port preserves all NAND programming code while moving platform configuration to Device Tree and replacing some kernel functions marked for retirement by 4.19. Suitable definition is included in 'ar934x.dtsi' ('nand@1b000200' section). Most important changes to ar71xx version are: * old kernel sections of code removed * 'bool swap_dma' provided by platform data is now set by boolean DT property 'qca,nand-swap-dma' * board-supplied (mach-*.c code) platform data removed - its elements become either unused, redundant or replaced by DT methods (like reset) * IRQ is reserved by devm_request_irq() so free_irq() is not needed anymore * calls to deprecated nand_scan_ident() + nand_scan_tail() function pair replaced by using recommended nand_scan() with attach_chip() callback * ECC is set to hardware by default, can be overriden by standard DT 'nand-ecc-*' properties (software Hamming or BCH are other options) This driver has been successfully tested on Netgear WNDR4300 running experimental ath79 OpenWrt master branch.

* ath79: port cybertan_part from ar71xxChristian Lamparter2018-09-101-0/+163
| | | | | | | | | | | | | This patch ports the cybertan_part code from ar71xx and converts the driver to a DT-supported mtd parser. As a result, it will no longer add the u-boot, nvram and art partitions, which were never part of the special Cybertan header. Instead these partitions have to be specified in the DT, which has the upside of making it possible to add properties (i.e.: read-only), labels and references to these important partitions.

* ath79: add new OF only target for QCA MIPS siliconJohn Crispin2018-05-071-0/+235
This target aims to replace ar71xx mid-term. The big part that is still missing is making the MMIO/AHB wifi work using OF. NAND and mikrotik subtargets will follow. Signed-off-by: John Crispin <john@phrozen.org>
