I've not run any tests, just looked at the patches, the stuff in
patch 3 is already present in arch/arm/boot/dts/sun5i-a13-q8-tablet.dts
I put it there because I saw some .fex files which don't use ldo3 for wifi
I'm fine with moving it to -common though, I believe that you're right
that it makes more sense there, having it in 2 places is not really
The other patches look good.
Thanks & Regards,
