- I2C for R-Car platforms
- Required properties:
- - compatible: Must be one of
- "renesas,i2c-rcar"
- "renesas,i2c-r8a7778"
- "renesas,i2c-r8a7779"
- "renesas,i2c-r8a7790"
- "renesas,i2c-r8a7791"
- "renesas,i2c-r8a7792"
- "renesas,i2c-r8a7793"
- "renesas,i2c-r8a7794"
- - reg: physical base address of the controller and length of memory mapped
- region.
- - interrupts: interrupt specifier.
- Optional properties:
- - clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
- propoerty indicates the default frequency 100 kHz.
- - clocks: clock specifier.
- Examples :
- i2c0: i2c@e6508000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "renesas,i2c-r8a7791";
- reg = <0 0xe6508000 0 0x40>;
- interrupts = <0 287 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp9_clks R8A7791_CLK_I2C0>;
- clock-frequency = <400000>;
- };
