Applied, thanks! [1/1] ARM: dts: rockchip: add adc-keys node to rk3066a-mk808.dts commit: d7197d56c9cf3620ec086550386df3be2c90ae4d Best regards,

The MK808 has a button inside the cover for the boot loader to do some action. Add the adc-keys node to the rk3066a-mk808.dts file. The rk3066 has a higher maximum DC supply voltage for the analog part of SAR-ADC VDDA_SARADC of 2.75V then other Rockchip SoCs. For the "rockchip,saradc" node is a vref-supply property required, so add a regulator for it as well.
