-ZTE zx2967 I2C controller
-
-Required properties:
- - compatible: must be "zte,zx296718-i2c"
- - reg: physical address and length of the device registers
- - interrupts: a single interrupt specifier
- - clocks: clock for the device
- - #address-cells: should be <1>
- - #size-cells: should be <0>
- - clock-frequency: the desired I2C bus clock frequency.
-
-Examples:
-
-	i2c@112000 {
-		compatible = "zte,zx296718-i2c";
-		reg = <0x00112000 0x1000>;
-		interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&osc24m>;
-		#address-cells = <1>
-		#size-cells = <0>;
-		clock-frequency = <1600000>;
-	};
