1* Ingenic JZ47xx ADC controller IIO bindings
2
3Required properties:
4
5- compatible: Should be one of:
6  * ingenic,jz4725b-adc
7  * ingenic,jz4740-adc
8  * ingenic,jz4770-adc
9- reg: ADC controller registers location and length.
10- clocks: phandle to the SoC's ADC clock.
11- clock-names: Must be set to "adc".
12- #io-channel-cells: Must be set to <1> to indicate channels are selected
13  by index.
14
15ADC clients must use the format described in iio-bindings.txt, giving
16a phandle and IIO specifier pair ("io-channels") to the ADC controller.
