-* Amlogic Meson SAR (Successive Approximation Register) A/D converter
-
-Required properties:
-- compatible: depending on the SoC this should be one of:
- - "amlogic,meson8-saradc" for Meson8
- - "amlogic,meson8b-saradc" for Meson8b
- - "amlogic,meson8m2-saradc" for Meson8m2
- - "amlogic,meson-gxbb-saradc" for GXBB
- - "amlogic,meson-gxl-saradc" for GXL
- - "amlogic,meson-gxm-saradc" for GXM
- - "amlogic,meson-axg-saradc" for AXG
- - "amlogic,meson-g12a-saradc" for AXG
- along with the generic "amlogic,meson-saradc"
-- reg: the physical base address and length of the registers
-- interrupts: the interrupt indicating end of sampling
-- clocks: phandle and clock identifier (see clock-names)
-- clock-names: mandatory clocks:
- - "clkin" for the reference clock (typically XTAL)
- - "core" for the SAR ADC core clock
- optional clocks:
- - "adc_clk" for the ADC (sampling) clock
- - "adc_sel" for the ADC (sampling) clock mux
-- vref-supply: the regulator supply for the ADC reference voltage
-- #io-channel-cells: must be 1, see ../iio-bindings.txt
-
-Optional properties:
-- amlogic,hhi-sysctrl: phandle to the syscon which contains the 5th bit
- of the TSC (temperature sensor coefficient) on
- Meson8b and Meson8m2 (which used to calibrate the
- temperature sensor)
-- nvmem-cells: phandle to the temperature_calib eFuse cells
-- nvmem-cell-names: if present (to enable the temperature sensor
- calibration) this must contain "temperature_calib"
-

-Example:
- saradc: adc@8680 {
- compatible = "amlogic,meson-gxl-saradc", "amlogic,meson-saradc";
- #io-channel-cells = <1>;
- reg = <0x0 0x8680 0x0 0x34>;
- interrupts = <GIC_SPI 73 IRQ_TYPE_EDGE_RISING>;
- clocks = <&xtal>,
- <&clkc CLKID_SAR_ADC>,
- <&clkc CLKID_SANA>,
- <&clkc CLKID_SAR_ADC_CLK>,
- <&clkc CLKID_SAR_ADC_SEL>;
- clock-names = "clkin", "core", "sana", "adc_clk", "adc_sel";
