-Allwinner SoCs' GPADC Device Tree bindings
-------------------------------------------
-The Allwinner SoCs all have an ADC that can also act as a thermal sensor
-and sometimes as a touchscreen controller.
-
-Required properties:
- - compatible: "allwinner,sun8i-a33-ths",
- - reg: mmio address range of the chip,
- - #thermal-sensor-cells: shall be 0,
- - #io-channel-cells: shall be 0,
-
-Example:
- ths: ths@1c25000 {
- compatible = "allwinner,sun8i-a33-ths";
- reg = <0x01c25000 0x100>;
- #thermal-sensor-cells = <0>;

-sun4i, sun5i and sun6i SoCs are also supported via the older binding:

-Required properties:
- - compatible: "allwinner,sun4i-a10-ts", "allwinner,sun5i-a13-ts" or

- adjust sensitivity of pen down detection
