+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 at 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>;
+ };
