| * Ingenic JZ4780 I2C Bus controller |
| |
| Required 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 function |
| |
| Optional properties: |
| - interrupt-parent: Should be the phandle of the interrupt controller that |
| delivers interrupts to the I2C block. |
| |
| Example |
| |
| / { |
| i2c4: i2c4@10054000 { |
| 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>; |
| |
| }; |
| }; |
