* ath79: ag71xx: support probe defferal for getting MAC addressRobert Marko2024-06-201-1/+5
| | | | | | | | | | | | Currently, of_get_ethdev_address() return is checked for any return error code which means that trying to get the MAC from NVMEM cells that is backed by MTD will fail if it was not probed before ag71xx. So, lets check the return error code for EPROBE_DEFER and defer the ag71xx probe in that case until the underlying NVMEM device is live.

| | | | | | | | | | | There is no need to use 'list_for_each_entry_safe' here, as nothing is removed from the list in the 'for' loop. Use 'list_for_each_entry' instead, it is slightly less verbose.

* ath79: add support for reset key on MikroTik RB912UAG-2HPnDDenis Kalashnikov2022-01-193-6/+240
| | | | | | | | | | | | | | | | | | | | | | On MikroTik RB91x board series a reset key shares SoC gpio line #15 with NAND ALE and NAND IO7. So we need a custom gpio driver to manage this non-trivial connection schema. Also rb91x-nand needs to have an ability to disable a polling of the key while it works with NAND. While we've been integrating rb91x-key into a firmware, we've figured out that: * In the gpio-latch driver we need to add a "cansleep" suffix to several gpiolib calls, * When gpio-latch and rb91x-nand fail to get a gpio and an error is -EPROBE_DEFER, they shouldn't report about this, since this actually is not an error and occurs when the gpio-latch probe function is called before the rb91x-key probe. We fix these related things here too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ag71xx_probe is registering ag71xx_interrupt as handler for the gmac0/gmac1 interrupts. The handler is trying to use napi_schedule to handle the processing of packets. But the netif_napi_add for this device is called a lot later in ag71xx_probe. It can therefore happen that a still running gmac0/gmac1 is triggering the interrupt handler with a bit from AG71XX_INT_POLL set in AG71XX_REG_INT_STATUS. The handler will then call napi_schedule and the napi code will crash the system because the ag->napi is not yet initialized: libphy: Fixed MDIO Bus: probed CPU 0 Unable to handle kernel paging request at virtual address 00000000, epc == 00000000, ra == 81373408 Oops[#1]: CPU: 0 PID: 1 Comm: swapper Not tainted 5.4.152 #0 $ 0 : 00000000 00000001 00000000 8280bf28 $ 4 : 82a98cb0 00000000 81620000 00200140 $ 8 : 00000000 00000000 74657272 7570743a $12 : 0000005b 8280bdb9 ffffffff ffffffff $16 : 00000001 82a98cb0 00000000 8280bf27 $20 : 8280bf28 81620000 ffff8b00 8280bf30 $24 : 00000000 8125af9c $28 : 82828000 8280bed8 81610000 81373408 Hi : 00005fff Lo : 2e48f657 epc : 00000000 0x0 ra : 81373408 __napi_poll+0x3c/0x11c Status: 1100dc03 KERNEL EXL IE Cause : 00800008 (ExcCode 02) BadVA : 00000000 PrId : 00019750 (MIPS 74Kc) Modules linked in: Process swapper (pid: 1, threadinfo=(ptrval), task=(ptrval), tls=00000000) Stack : ffff8afb ffff8afa 81620000 00200140 00000000 82a98cb0 00000008 0000012c 81625620 81373684 ffffffff ffffffff ffffffef 00000008 816153d8 81620000 815b0d60 815bbd54 00000000 81753700 8280bf28 8280bf28 8280bf30 8280bf30 81753748 00000008 00000003 00000004 0000000c 00000100 3fffffff 8175373c 816059f0 814ddb48 00000001 8160ab30 81615488 810618bc 00000006 00000000 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the option to disable subpage writing is only set when a HW ECC engine is used. Some boards lack a HW ECC engine and use software for that. In this case, this NAND option does not get set when the NAND chip does not support it, resulting in mounting errors. Move the setting of this option to a generic init location so it gets set for all types where required. While at it, also OR the option instead of just setting it so we don't overwrite potential flags being set somewhere else.

| | | | | | | | | | | | | | | | | The mode on the SGMII SerDes on the QCA9563 is 1000 Base-X by default. This only allows for 1000 Mbit/s links, however when used with an SGMII PHY in 100 Mbit/s link mode, the link remains dead. This strictly has nothing to do with the SerDes calibration, however it is done at the same point in the QCA reference U-Boot which is the blueprint for everything happening here. As the current state is more or less a hack, this should be fine. This fixes the issues outlined above on a TP-Link EAP-225 Outdoor.

| | | | | | | | | | | | | | | | | | | | | | | This commit add a workaround for non working SGMII link observed on some QCA956x SoCs. The workaround originates part from the U-Boot source code from QCA, part from the implementation from TP-Link found in the GPL tarball for the EAP245v1. Extends commit 0d416a8d3b990e3b78628f0e7546527709c877f7 for QCA956x. Note that reset is the same on QCA955x and QCA956x, same register offset and values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds 3 Mikrotik rb4xx series drivers as follows: rb4xx-cpld: This is in the mfd subsystem, and is the parent CPLD device that interfaces between the SoC SPI bus and its two children below. rb4xx-gpio: This is the GPIO expander. rb4xx-nand: This is the NAND driver.

* ath79: use downstream ag71xx for Kernel 5.4David Bauer2020-03-139-0/+3106
| | | | | | | | | | | | | | | | | | | The ag71xx driver from Linux 5.4 currently has various shortcomings when used with OpenWrt compared to our downstream version. For example, the upstream driver does not support modifying the ethernet clock and configuring RGMII delays on the MAC side. While we should certainly switch to the upstream driver, the amount of necessary patches would make it cumbersome to work with. It's also highly likely we won't be able to finish patching the upstream driver in time for a Linux 5.4 release. Tested on Siemens WS-AP3610.

* ath79: add QCA955x SGMII link loss workaroundDavid Bauer2020-01-231-0/+108
| | | | | | | | | | | | | | | | This commit adds a workaround for the loss of the SGMII link observed on the QCA955x generation of SoCs. The workaround originates part from the U-Boot source code, part from the implementation from AVM found in the GPL tarball for the AVM FRITZ!WLAN Repeater 450E. The bug results in a stuck SGMII link between the PHY device and the SoC side. This has only been observed with the Atheros AR8033 PHY and most likely all devices using such combination are affected. It is worked around by reading a hidden SGMII status register and issuing a SGMII PHY reset until the link becomes useable again. Signed-off-by: David Bauer <mail@david-bauer.net>
* 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.
