[PATCH 0/2] Add Meson SAR ADC support for G12A

[Neil Armstrong]

These patches adds SAR ADC support for the G12A SoCs, using
the same setup/configuration as AXG and GXL.

The only change is the clocks, they are now handled by the AO
Clock Controller, but it doesn't change the bindings or the driver.

Applied to the togreg branch of iio.git and pushed out
as testing to be completely ignored ;)

this new compatible string will be especially useful when we want to
add "buffer" support which was reworked in the IP block with G12A

Good to know. Thanks.

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.

Thanks,
