1* Amlogic Meson SAR (Successive Approximation Register) A/D converter
2
3Required properties:
4- compatible:	depending on the SoC this should be one of:
5			- "amlogic,meson8-saradc" for Meson8
6			- "amlogic,meson8b-saradc" for Meson8b
7			- "amlogic,meson8m2-saradc" for Meson8m2
8			- "amlogic,meson-gxbb-saradc" for GXBB
9			- "amlogic,meson-gxl-saradc" for GXL
10			- "amlogic,meson-gxm-saradc" for GXM
11			- "amlogic,meson-axg-saradc" for AXG
12			- "amlogic,meson-g12a-saradc" for AXG
13		along with the generic "amlogic,meson-saradc"
14- reg:		the physical base address and length of the registers
15- interrupts:	the interrupt indicating end of sampling
16- clocks:	phandle and clock identifier (see clock-names)
17- clock-names:	mandatory clocks:
18			- "clkin" for the reference clock (typically XTAL)
19			- "core" for the SAR ADC core clock
20		optional clocks:
21			- "adc_clk" for the ADC (sampling) clock
22			- "adc_sel" for the ADC (sampling) clock mux
23- vref-supply:	the regulator supply for the ADC reference voltage
24- #io-channel-cells: must be 1, see ../iio-bindings.txt
25
26Optional properties:
27- amlogic,hhi-sysctrl:	phandle to the syscon which contains the 5th bit
28			of the TSC (temperature sensor coefficient) on
29			Meson8b and Meson8m2 (which used to calibrate the
30			temperature sensor)
31- nvmem-cells:		phandle to the temperature_calib eFuse cells
32- nvmem-cell-names:	if present (to enable the temperature sensor
33			calibration) this must contain "temperature_calib"

36Example:
37	saradc: adc@8680 {
38		compatible = "amlogic,meson-gxl-saradc", "amlogic,meson-saradc";
39		#io-channel-cells = <1>;
40		reg = <0x0 0x8680 0x0 0x34>;
41		interrupts = <GIC_SPI 73 IRQ_TYPE_EDGE_RISING>;
42		clocks = <&xtal>,
43			 <&clkc CLKID_SAR_ADC>,
44			 <&clkc CLKID_SANA>,
45			 <&clkc CLKID_SAR_ADC_CLK>,
46			 <&clkc CLKID_SAR_ADC_SEL>;
47		clock-names = "clkin", "core", "sana", "adc_clk", "adc_sel";
48	};
