[PATCH v3 0/3] Add GPADC support for A523

[Michal Piekos]

Add support for Allwinner A523 GPADC in sun20i gpadc driver and describe
corresponding node in dts for A523 SoC.

A523 uses same model as existing driver except it has two clocks.

Added support to enable more than one clock in the driver, extended the
binding with new compatible and wired up dts node for A523 as its own
fallback compatible.
