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]
