| 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>; |
| }; |
