Kernel-4.18.0-80.el8_rockchip-saradc

Rockchip Successive Approximation Register (SAR) A/D Converter bindings

Required properties:

  • compatible: should be “rockchip,-saradc” or “rockchip,rk3066-tsadc”

    • “rockchip,saradc”: for rk3188, rk3288
    • “rockchip,rk3066-tsadc”: for rk3036
    • “rockchip,rk3328-saradc”, “rockchip,rk3399-saradc”: for rk3328
    • “rockchip,rk3399-saradc”: for rk3399
    • “rockchip,rv1108-saradc”, “rockchip,rk3399-saradc”: for rv1108
  • reg: physical base address of the controller and length of memory mapped

     region.
    
  • interrupts: The interrupt number to the cpu. The interrupt specifier format

            depends on the interrupt controller.
    
  • clocks: Must contain an entry for each entry in clock-names.

  • clock-names: Shall be “saradc” for the converter-clock, and “apb_pclk” for

             the peripheral clock.
    
  • vref-supply: The regulator supply ADC reference voltage.

  • #io-channel-cells: Should be 1, see ../iio-bindings.txt

Optional properties:

  • resets: Must contain an entry for each entry in reset-names if need support
    this option. See ../reset/reset.txt for details.
    
  • reset-names: Must include the name “saradc-apb”.

Example:
saradc: saradc@2006c000 {
compatible = “rockchip,saradc”;
reg = <0x2006c000 0x100>;
interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cru SCLK_SARADC>, <&cru PCLK_SARADC>;
clock-names = “saradc”, “apb_pclk”;
resets = <&cru SRST_SARADC>;
reset-names = “saradc-apb”;
#io-channel-cells = <1>;
vref-supply = <&vcc18>;
};
