UniPhier I2C controller (FIFO-less)
|
|
Required properties:
|
- compatible: should be "socionext,uniphier-i2c".
|
- #address-cells: should be 1.
|
- #size-cells: should be 0.
|
- reg: offset and length of the register set for the device.
|
- interrupts: a single interrupt specifier.
|
- clocks: phandle to the input clock.
|
|
Optional properties:
|
- clock-frequency: desired I2C bus frequency in Hz. The maximum supported
|
value is 400000. Defaults to 100000 if not specified.
|
|
Examples:
|
|
i2c0: i2c@58400000 {
|
compatible = "socionext,uniphier-i2c";
|
reg = <0x58400000 0x40>;
|
#address-cells = <1>;
|
#size-cells = <0>;
|
interrupts = <0 41 1>;
|
clocks = <&i2c_clk>;
|
clock-frequency = <100000>;
|
};
