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 <shinoda@jaist.ac.jp> SVN-Revision: 33294master
