The Radxa E20C has two buttons, one SARADC maskrom button and one GPIO
user button.

This series adds dt-binding, driver support, DT node in SoC .dtsi and
adc-keys node in board DT to support the maskrom button.

  dt-bindings: iio: adc: Add rockchip,rk3528-saradc variant
  iio: adc: rockchip_saradc: Add support for RK3528
  arm64: dts: rockchip: Add SARADC node for RK3528
