Subject: mediatek: fix ledbar of UniFi 6 LR when running custom U-Boot
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7a26f40217b0a00d8f2ce2c56236f9bef39d1351;p=openwrt%2Fstaging%2Fblocktrron.git

mediatek: fix ledbar of UniFi 6 LR when running custom U-Boot

The RGB LED of the UniFi 6 LR v1 doesn't work when using the Openwrt-
built U-Boot. This is because the vendor loader resets the ledbar
controller while our U-Boot doesn't care.
Add reset-gpio so the ledbar driver in Linux will always reset the
ledbar controller.
