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 along with the generic "amlogic,meson-saradc" 13- reg: the physical base address and length of the registers 14- interrupts: the interrupt indicating end of sampling 15- clocks: phandle and clock identifier (see clock-names) 16- clock-names: mandatory clocks: 17 - "clkin" for the reference clock (typically XTAL) 18 - "core" for the SAR ADC core clock 19 optional clocks: 20 - "adc_clk" for the ADC (sampling) clock 21 - "adc_sel" for the ADC (sampling) clock mux 22- vref-supply: the regulator supply for the ADC reference voltage 23- #io-channel-cells: must be 1, see ../iio-bindings.txt 24 25Example: 26 saradc: adc@8680 { 27 compatible = "amlogic,meson-gxl-saradc", "amlogic,meson-saradc"; 28 #io-channel-cells = <1>; 29 reg = <0x0 0x8680 0x0 0x34>; 30 interrupts = <GIC_SPI 73 IRQ_TYPE_EDGE_RISING>; 31 clocks = <&xtal>, 32 <&clkc CLKID_SAR_ADC>, 33 <&clkc CLKID_SANA>, 34 <&clkc CLKID_SAR_ADC_CLK>, 35 <&clkc CLKID_SAR_ADC_SEL>; 36 clock-names = "clkin", "core", "sana", "adc_clk", "adc_sel"; 37 }; 38
