Hi,
This series adds support for general purpose ADC (GPADC) on new
Allwinner's SoCs, such as D1, T113s and R329. The implemented driver
provides basic functionality for getting ADC channels data.
All of the listed SoCs have the same IP. The only difference is the number
of available channels:
T113 - 1 channel
D1 - 2 channels
R329 - 4 channels
This series is just an RFC and I would be glad to see any comments
about it.
