+Allwinner sun4i Low Resolution ADC
+----------------------------------
+
+Required properties:
+ - compatible: "allwinner,sun4i-a10-lradc"
+ - reg: mmio address range of the chip
+ - interrupts: interrupt to which the chip is connected
+ - vref-supply: powersupply for the lradc reference voltage
+ - #io-channel-cells = <1>; As ADC has multiple outputs
+
+Example:
+
+ lradc: lradc@01c22800 {
+ compatible = "allwinner,sun4i-a10-lradc";
+ reg = <0x01c22800 0x100>;
+ interrupts = <31>;
+ vref-supply = <®_vcc3v0>;
+ #io-channel-cells = <1>;
+ };
