* Ingenic JZ4780 I2C Bus controllerRequired properties:- compatible: should be "ingenic,jz4780-i2c"- reg: Should contain the address & size of the I2C controller registers.- interrupts: Should specify the interrupt provided by parent.- clocks: Should contain a single clock specifier for the JZ4780 I2C clock.- clock-frequency: desired I2C bus clock frequency in Hz.Recommended properties:- pinctrl-names: should be "default";- pinctrl-0: phandle to pinctrl functionOptional properties:- interrupt-parent: Should be the phandle of the interrupt controller that delivers interrupts to the I2C block.Example/ { i2c4: i2c4@0x10054000 { compatible = "ingenic,jz4780-i2c"; reg = <0x10054000 0x1000>; interrupt-parent = <&intc>; interrupts = <56>; clocks = <&cgu JZ4780_CLK_SMB4>; clock-frequency = <100000>; pinctrl-names = "default"; pinctrl-0 = <&pins_i2c4_data>; };};
