* AT91 SAMA5D2 Analog to Digital Converter (ADC)
Required properties:
- compatible: Should be "atmel,sama5d2-adc".
- reg: Should contain ADC registers location and length.
- interrupts: Should contain the IRQ line for the ADC.
- clocks: phandle to device clock.
- clock-names: Must be "adc_clk".
- vref-supply: Supply used as reference for conversions.
- vddana-supply: Supply for the adc device.
- atmel,min-sample-rate-hz: Minimum sampling rate, it depends on SoC.
- atmel,max-sample-rate-hz: Maximum sampling rate, it depends on SoC.
- atmel,startup-time-ms: Startup time expressed in ms, it depends on SoC.
Example:
adc: adc@fc030000 {
compatible = "atmel,sama5d2-adc";
reg = <0xfc030000 0x100>;
interrupts = <40 IRQ_TYPE_LEVEL_HIGH 7>;
clocks = <&adc_clk>;
clock-names = "adc_clk";
atmel,min-sample-rate-hz = <200000>;
atmel,max-sample-rate-hz = <20000000>;
atmel,startup-time-ms = <4>;
vddana-supply = <&vdd_3v3_lp_reg>;
vref-supply = <&vdd_3v3_lp_reg>;
