Spreadtrum SC27XX series PMICs ADC binding
Required properties:
- compatible: Should be one of the following.
"sprd,sc2720-adc"
"sprd,sc2721-adc"
"sprd,sc2723-adc"
"sprd,sc2730-adc"
"sprd,sc2731-adc"
- reg: The address offset of ADC controller.
- interrupt-parent: The interrupt controller.
- interrupts: The interrupt number for the ADC device.
- #io-channel-cells: Number of cells in an IIO specifier.
- hwlocks: Reference to a phandle of a hwlock provider node.
- nvmem-cells: A phandle to the calibration cells provided by eFuse device.
- nvmem-cell-names: Should be "big_scale_calib", "small_scale_calib".
Example:
sc2731_pmic: pmic@0 {
compatible = "sprd,sc2731";
reg = <0>;
spi-max-frequency = <26000000>;
interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
interrupt-controller;
#interrupt-cells = <2>;
#address-cells = <1>;
#size-cells = <0>;
pmic_adc: adc@480 {
compatible = "sprd,sc2731-adc";
reg = <0x480>;
interrupt-parent = <&sc2731_pmic>;
interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
#io-channel-cells = <1>;
hwlocks = <&hwlock 4>;
nvmem-cells = <&adc_big_scale>, <&adc_small_scale>;
nvmem-cell-names = "big_scale_calib", "small_scale_calib";
};
};
