|
|
|
||
|
|
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>;
|
||

|
|
interrupts = <0 287 IRQ_TYPE_LEVEL_HIGH>;
|
||
|
