[OpenWrt-Devel] [PATCH 4/6] [kernel] ath79: all LEDs and buttons for Netgear WNR2000v3
Michal Cieslakiewicz

Wed Jan 20 18:12:41 EST 2016
From: Michal Cieslakiewicz <michal.cieslakiewicz at wp.pl>
This patch provides full GPIO support for WNR2000v3 (LEDs and buttons).
It exposes all LEDs to operating system, including Ethernet ones.
Signed-off-by: Michal Cieslakiewicz <michal.cieslakiewicz at wp.pl>
---
This patch contains correct definitions of all LEDs and buttons for WNR2000v3,
both platform (attached to SoC) and additional ones (connected with wireless
chip). Extra name field is reserved for WLAN LED that is handled in a special
way by ath9k module - now it follows 'vendor:colour:function' scheme instead
of generic 'ath9k-phyX' name.
Based on analysis of GPL'ed u-boot sources from Netgear site, AR7241 chip is
reprogrammed to drive LEDs instead of JTAG and release control of Ethernet
lights to operating system. Default OpenWRT configuration is in place.
This patch requires kernel source with 3 earlier patches from this set applied:
* ath9k: enable GPIO access for ar9287 and ar9285
* ath9k: be verbose if platform-supplied hardware MAC is used
* ath79: new functions for passing GPIO data to wireless module
