| Rockchip Successive Approximation Register (SAR) A/D Converter bindings |
| |
| Required properties: |
| - compatible: should be "rockchip,<name>-saradc" or "rockchip,rk3066-tsadc" |
| - "rockchip,saradc": for rk3188, rk3288 |
| - "rockchip,rk3066-tsadc": for rk3036 |
| - "rockchip,rk3399-saradc": for rk3399 |
| |
| - 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 |
| |
| 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"; |
| #io-channel-cells = <1>; |
| vref-supply = <&vcc18>; |
| }; |
