1 | Rockchip Successive Approximation Register (SAR) A/D Converter bindings |
| 2 | ||
| 3 | Required properties: | |
| ae549a72 DW |
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 | |

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 | |

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". | |
