   3 Required properties:
   4 - compatible: should be "rockchip,<name>-saradc" or "rockchip,rk3066-tsadc"
   5    - "rockchip,saradc": for rk3188, rk3288

  10 - reg: physical base address of the controller and length of memory mapped
  11        region.
  12 - interrupts: The interrupt number to the cpu. The interrupt specifier format
  13               depends on the interrupt controller.
  14 - clocks: Must contain an entry for each entry in clock-names.
  15 - clock-names: Shall be "saradc" for the converter-clock, and "apb_pclk" for
  16                the peripheral clock.
  17 - vref-supply: The regulator supply ADC reference voltage.
  18 - #io-channel-cells: Should be 1, see ../iio-bindings.txt
  19
  20 Optional properties:
  21 - resets: Must contain an entry for each entry in reset-names if need support
  22           this option. See ../reset/reset.txt for details.
  23 - reset-names: Must include the name "saradc-apb".
