[OpenWrt-Devel] [PATCH v2 0/4] ath79: add support for QCA9563-based Netgear WNDR routers

This patchset introduces support for two Netgear dual-band routers
based on the same PCB (29764821) with QCA9563 SoC, AR9580 5GHz chip,
128 MiB RAM, 2 MiB SPI-NOR + 128 MiB SPI-NAND flash:
* Netgear WNDR4300 v2
* Netgear WNDR4500 v3

WNDR4300v2 has been tested successfully with this patchset applied
to master branch. Since I have no access to 4500v3, configuration
for this device is based on information provided by various websites,
including abandoned ar71xx patch https://patchwork.ozlabs.org/patch/809227/

Note: technical wikis claim device is running CPU @ 750 MHz, while on my
WNDR4300v2 both u-boot and OpenWrt report CPU clock value of 775 MHz.

MAC address printed on device label is for LAN interface (ART offset 0x0).

Patch #1 is a prerequisite and allows to unmask certain pins for
ath9k-compatible wireless chips using Device Tree definition. Parameter
is labelled "qca,gpio-mask" and accepts u32 value (see *_GPIO_MASK
constants in ath9k/reg.h file). One of main reasons for blocking access
to these pins is that they provide only one-way communication (in or out).
Here - setting new mask to 0xf6ff (default one is 0xf4ff) enables RFKILL
button wired to input pin 9.

Changes v1->v2:
* kernel partition size increased from 2 MiB to 4 MiB for all Netgear WNDR
  routers with NAND flash, including AR9344 models (WNDR4300 and WNDR3700v4)
  already in master (patch 2/4 added)
* dropped 'firmware' overlay partition

Patch list (4):
  mac80211: ath9k: add GPIO mask dts property
  ath79: WNDR4300: increase kernel partition to 4M
  ath79: add support for Netgear WNDR4300 v2
  ath79: add support for Netgear WNDR4500 v3
