Subject: [PATCH v2 0/3] Add support for Allwinner GPADC on D1/T113s/R329/T507 SoCs

This series adds support for general purpose ADC (GPADC) on new
Allwinner's SoCs, such as D1, T113s, T507 and R329. The implemented driver
provides basic functionality for getting ADC channels data.

Change History:
v2:
- Added lastch flag to avoid addition work for already selected channel
- Added reset assertion on module remove
- Added dynamic channel allocation and dropped iio_chan_spec arrays
- Changed IIO_CHAN_INFO_SCALE type to FRACTIONAL_LOG2
- Dropped separate compatible strings and configs for T113s and R329
- Fixed includes
- Fixed Kconfig description
- Removed duplicate probe error messages
- Used FIELD_PREP for bit setup

v1:
- Initial version
