dm: adc: add simple ADC uclass implementation 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>

config ADC
bool "Enable ADC drivers using Driver Model"
help
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
dm: adc: add Exynos54xx compatible ADC driver This commit adds driver for Exynos54xx ADC subsystem. The driver is implemented using driver model, amd provides ADC uclass's methods for ADC single channel operations: - adc_start_channel() - adc_channel_data() - adc_stop() The basic parameters of ADC conversion, are: - sample rate: 600KSPS - output the data as average of 8 time conversion ADC features: - sample rate: 600KSPS - resolution: 12-bit - channels: 10 (analog multiplexer) Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Minkyu Kang <mk7.kang@samsung.com> Cc: Simon Glass <sjg@chromium.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

adc: add Amlogic Meson SAR ADC driver 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.

adc: Add driver for STM32 ADC This patch adds support for STMicroelectronics STM32 ADC (analog to digital converter). It's originally based on Linux kernel v4.18-rcs drivers/iio/adc/stm32-adc*. It's composed of: - core driver (UCLASS_SIMPLE_BUS) manages common resources (clk, regu). - child drivers (UCLASS_ADC) declare each ADC, channels and handle conversions. This driver currently supports STM32H7 and STM32MP1 ADC. Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>

bool "Enable STMicroelectronics STM32 ADC driver"
depends on ADC && (STM32H7 || ARCH_STM32MP)
help
This enables driver for STMicroelectronics STM32 analog-to-digital
converter (ADC).
A STM32 ADC block can be composed of several individual ADCs.
Each has its own private registers, but shares some resources:
- clock selection and prescaler
- voltage reference
- common registers area.
STM32 ADC driver is composed of:
- core driver to deal with common resources
- child driver to deal with individual ADC resources (declare ADC
device and associated channels, start/stop conversions)
