1*c66ec88fSEmmanuel VadotFreescale imx7d ADC bindings
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotThe devicetree bindings are for the ADC driver written for
4*c66ec88fSEmmanuel Vadotimx7d SoC.
5*c66ec88fSEmmanuel Vadot
6*c66ec88fSEmmanuel VadotRequired properties:
7*c66ec88fSEmmanuel Vadot- compatible: Should be "fsl,imx7d-adc"
8*c66ec88fSEmmanuel Vadot- reg: Offset and length of the register set for the ADC device
9*c66ec88fSEmmanuel Vadot- interrupts: The interrupt number for the ADC device
10*c66ec88fSEmmanuel Vadot- clocks: The root clock of the ADC controller
11*c66ec88fSEmmanuel Vadot- clock-names: Must contain "adc", matching entry in the clocks property
12*c66ec88fSEmmanuel Vadot- vref-supply: The regulator supply ADC reference voltage
13*c66ec88fSEmmanuel Vadot- #io-channel-cells: Must be 1 as per ../iio-bindings.txt
