Description
all test so far indicate that power amplifier on this device doesn't function.
with stock fw power level is between 80 and 90% on ubuntu notebook but with openwrt about 50-60% if the power isn't raised in chip directly with https://github.com/openwrt/mt76/commit/1413f553f866e9ae53871013294c25ff85588cf3
the information available in MT7612E datasheet suggest to enable GPIO 13 and 14 in IO_MODE 7 for PA to work.
can someone implement this in driver code?
