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.

Enable CPU opp tables for OrangePi One Plus. This needs to change the CPU regulator max voltage to fit the OPP table. Signed-off-by: Chukun Pan <amadeus@jmu.edu.cn> --- arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi.dtsi | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-)
