1* Ingenic JZ4780 I2C Bus controller
2
3Required properties:
4- compatible: should be "ingenic,jz4780-i2c"
5- reg: Should contain the address & size of the I2C controller registers.
6- interrupts: Should specify the interrupt provided by parent.
7- clocks: Should contain a single clock specifier for the JZ4780 I2C clock.
8- clock-frequency: desired I2C bus clock frequency in Hz.
9
10Recommended properties:
11- pinctrl-names: should be "default";
12- pinctrl-0: phandle to pinctrl function
13
14Optional properties:
15- interrupt-parent: Should be the phandle of the interrupt controller that
16  delivers interrupts to the I2C block.
