Putting the changes in this file also applies them to the OrangePi Lite2 and OrangePi 3.
Did you test OrangePi Lite2? They both use the same PMIC with a similar configuration, so it may be safe to assume that what works on OrangePi One Plus also works there, but I am not sure.
OrangePi 3 already includes the OPP header and these changes, so it is safe but redundant.
Either these changes need to be made in sun50i-h6-orangepi-one-plus.dts, or we need to remove the duplicate changes from sun50i-h6-orangepi-3.dts.
