Freescale vf610 Analog to Digital Converter bindings
|
||||
|
||||
The devicetree bindings are for the new ADC driver written for
|
||||
vf610/i.MX6slx and upward SoCs from Freescale.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should contain "fsl,vf610-adc"
|
||||
- reg: Offset and length of the register set for the device
|
||||
- interrupts: Should contain the interrupt for the device
|
||||
- clocks: The clock is needed by the ADC controller, ADC clock source is ipg clock.
|
||||
- clock-names: Must contain "adc", matching entry in the clocks property.
|
||||
- vref-supply: The regulator supply ADC refrence voltage.
|
||||
|
||||
Example:
|
||||
adc0: adc@4003b000 {
|
||||
compatible = "fsl,vf610-adc";
|
||||
reg = <0x4003b000 0x1000>;
|
||||
interrupts = <0 53 0x04>;
|
||||
clocks = <&clks VF610_CLK_ADC0>;
|
||||
clock-names = "adc";
|
||||
vref-supply = <®_vcc_3v3_mcu>;
|
||||
};
