   1 Rockchip Successive Approximation Register (SAR) A/D Converter bindings
   2
   3 Required properties:
   4 - compatible: should be "rockchip,<name>-saradc" or "rockchip,rk3066-tsadc"
   5    - "rockchip,saradc": for rk3188, rk3288
   6    - "rockchip,rk3066-tsadc": for rk3036
   7    - "rockchip,rk3399-saradc": for rk3399
   8
   9 - reg: physical base address of the controller and length of memory mapped
  10        region.
  11 - interrupts: The interrupt number to the cpu. The interrupt specifier format
  12               depends on the interrupt controller.
  13 - clocks: Must contain an entry for each entry in clock-names.
  14 - clock-names: Shall be "saradc" for the converter-clock, and "apb_pclk" for
  15                the peripheral clock.
  16 - vref-supply: The regulator supply ADC reference voltage.
  17 - #io-channel-cells: Should be 1, see ../iio-bindings.txt
  18
  19 Optional properties:
  20 - resets: Must contain an entry for each entry in reset-names if need support
  21           this option. See ../reset/reset.txt for details.
  22 - reset-names: Must include the name "saradc-apb".

  24 Example:
  25         saradc: saradc@2006c000 {
  26                 compatible = "rockchip,saradc";
  27                 reg = <0x2006c000 0x100>;
  28                 interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;
  29                 clocks = <&cru SCLK_SARADC>, <&cru PCLK_SARADC>;
  30                 clock-names = "saradc", "apb_pclk";
  31                 resets = <&cru SRST_SARADC>;
  32                 reset-names = "saradc-apb";
  33                 #io-channel-cells = <1>;
  34                 vref-supply = <&vcc18>;
  35         };
