This commit adds: - new uclass id: UCLASS_ADC - new uclass driver: drivers/adc/adc-uclass.c The new uclass's API allows for ADC operation on: * single-channel with channel selection by a number * multti-channel with channel selection by bit mask ADC uclass's functions: * single-channel: - adc_start_channel() - start channel conversion - adc_channel_data() - get conversion data - adc_channel_single_shot() - start/get conversion data * multi-channel: - adc_start_channels() - start selected channels conversion - adc_channels_data() - get conversion data - adc_channels_single_shot() - start/get conversion data for channels selected by bit mask * general: - adc_stop() - stop the conversion - adc_vdd_value() - positive reference Voltage value with polarity [uV] - adc_vss_value() - negative reference Voltage value with polarity [uV] - adc_data_mask() - conversion data bit mask The device tree can provide below constraints/properties: - vdd-polarity-negative: if true: Vdd = vdd-microvolts * (-1) - vss-polarity-negative: if true: Vss = vss-microvolts * (-1) - vdd-supply: phandle to Vdd regulator's node - vss-supply: phandle to Vss regulator's node And optional, checked only if the above corresponding, doesn't exist: - vdd-microvolts: positive reference Voltage [uV] - vss-microvolts: negative reference Voltage [uV] Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Simon Glass <sjg@chromium.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

help
|
|
Some SoCs use a different address map for CPU physical addresses and
|
|
peripheral DMA master accesses. If yours does, select this option in
|
|
your platform's Kconfig, and implement the appropriate mapping
|
|
functions in your platform's support code.
