From 5fdbb33db4080baa66eec736647c9028cb215750 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 29 Aug 2012 10:11:55 +0000 Subject: [PATCH] ar71xx: Buffalo WZR-HP-AG300H LED support An improved LED support for Buffalo WZR-HP-AG300H. There will be two new packages to go with this patch (ar922x-led-fix-hotplug and ar922x-led-fix-init). These packages essentially perform the same task of disabling "JTAG over GPIO pins" function which is currently required for LEDs on AR922x emac GPIO to work, and are both considered a temporary fix that circumvent this problem. [juhosg: add the hotplug script from the proposed ar922x-led-fix-hotplug package to ar71xx/base-files] Signed-off-by: Yoichi Shinoda SVN-Revision: 33294 --- target/linux/ar71xx/base-files/etc/diag.sh | 1 + .../etc/hotplug.d/net/10-ar922x-led-fix | 51 +++++++++++++++++ .../ar71xx/base-files/etc/uci-defaults/leds | 6 ++ .../arch/mips/ath79/mach-wzr-hp-ag300h.c | 56 +++++++++++++++++++ 4 files changed, 114 insertions(+) create mode 100644 target/linux/ar71xx/base-files/etc/hotplug.d/net/10-ar922x-led-fix diff --git a/target/linux/ar71xx/base-files/etc/diag.sh b/target/linux/ar71xx/base-files/etc/diag.sh index 6759cf0437..420d690245 100755 --- a/target/linux/ar71xx/base-files/etc/diag.sh +++ b/target/linux/ar71xx/base-files/etc/diag.sh @@ -150,6 +150,7 @@ get_status_led() { wlae-ag300n) status_led="buffalo:green:status" ;; + wzr-hp-ag300h | \ wzr-hp-g300nh2) status_led="buffalo:red:diag" ;; diff --git a/target/linux/ar71xx/base-files/etc/hotplug.d/net/10-ar922x-led-fix b/target/linux/ar71xx/base-files/etc/hotplug.d/net/10-ar922x-led-fix new file mode 100644 index 0000000000..102415009b --- /dev/null +++ b/target/linux/ar71xx/base-files/etc/hotplug.d/net/10-ar922x-led-fix @@ -0,0 +1,51 @@ +#!/bin/sh + +# For AR9220 and AR9223, GPIO JTAG must explicit be disabled +# before LEDs start working.
