Device tree configuration for Renesas IIC (sh_mobile) driver
|
|
|
|
Required properties:
|
|
- compatible : "renesas,iic-<soctype>". "renesas,rmobile-iic" as fallback
|
|
Examples with soctypes are:
|
|
- "renesas,iic-r8a73a4" (R-Mobile APE6)
|
|
- "renesas,iic-r8a7740" (R-Mobile A1)
|
|
- "renesas,iic-r8a7790" (R-Car H2)
|
|
- "renesas,iic-r8a7791" (R-Car M2-W)
|
|
- "renesas,iic-r8a7792" (R-Car V2H)
|
|
- "renesas,iic-r8a7793" (R-Car M2-N)
|
|
- "renesas,iic-r8a7794" (R-Car E2)
|
|
- "renesas,iic-sh73a0" (SH-Mobile AG5)
|
|
- reg : address start and address range size of device
|
|
- interrupts : interrupt of device
|
|
- clocks : clock for device
|
|
- #address-cells : should be <1>
|
|
- #size-cells : should be <0>
|
|
|
|
Optional properties:
|
|
- clock-frequency : frequency of bus clock in Hz. Default 100kHz if unset.
|
|
|
|
Pinctrl properties might be needed, too. See there.
|
|
|
|
Example:
|
|
|
|
iic0: i2c@e6500000 {
|
|
compatible = "renesas,iic-r8a7790", "renesas,rmobile-iic";
|
|
reg = <0 0xe6500000 0 0x425>;
|
|
interrupts = <0 174 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&mstp3_clks R8A7790_CLK_IIC0>;
|
|
clock-frequency = <400000>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
};
