This patch adds the driver for the Amlogic Meson Successive Approximation Register (SAR) A/D Converter based on the Linux IIO driver thanks to the great work of Martin Blumenstingl. The driver has been adapted to U-Boot and the ADC UClass. This patch depends on the regmap "regmap: add regmap_update_bits() helper" patch and has been tested using the newly introducted "adc" CLI command in the "cmd: add ADC cli commands" patch.

This enables ADC API for drivers, which allows driving ADC features
|
|
by single and multi-channel methods for:
|
|
- start/stop/get data for conversion of a single-channel selected by
|
|
a number or multi-channels selected by a bitmask
|
|
- get data mask (ADC resolution)
|
|
ADC reference Voltage supply options:
|
|
- methods for get Vdd/Vss reference Voltage values with polarity
|
|
- support supply's phandle with auto-enable
|
|
- supply polarity setting in fdt
