Socionext SynQuacer I2C
Required properties:
- compatible : Must be "socionext,synquacer-i2c"
- reg : Offset and length of the register set for the device
- interrupts : A single interrupt specifier
- #address-cells : Must be <1>;
- #size-cells : Must be <0>;
- clock-names : Must contain "pclk".
- clocks : Must contain an entry for each name in clock-names.
(See the common clock bindings.)
Optional properties:
- clock-frequency : Desired I2C bus clock frequency in Hz. As only Normal and
Fast modes are supported, possible values are 100000 and
400000.
Example :
i2c@51210000 {
compatible = "socionext,synquacer-i2c";
reg = <0x51210000 0x1000>;
interrupts = <GIC_SPI 165 IRQ_TYPE_LEVEL_HIGH>;
#address-cells = <1>;
#size-cells = <0>;
clock-names = "pclk";
clocks = <&clk_i2c>;
clock-frequency = <400000>;
};
