Device tree configuration for Renesas IIC (sh_mobile) driver
|
|
|
|
Required properties:
|
|
- compatible :
|
|
- "renesas,iic-r8a73a4" (R-Mobile APE6)
|
|
- "renesas,iic-r8a7740" (R-Mobile A1)
|
|
- "renesas,iic-r8a7743" (RZ/G1M)
|
|
- "renesas,iic-r8a7744" (RZ/G1N)
|
|
- "renesas,iic-r8a7745" (RZ/G1E)
|
|
- "renesas,iic-r8a774a1" (RZ/G2M)
|
|
- "renesas,iic-r8a774c0" (RZ/G2E)
|
|
- "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-r8a7795" (R-Car H3)
|
|
- "renesas,iic-r8a7796" (R-Car M3-W)
|
|
- "renesas,iic-r8a77965" (R-Car M3-N)
|
|
- "renesas,iic-r8a77990" (R-Car E3)
|
|
- "renesas,iic-sh73a0" (SH-Mobile AG5)
|
|
- "renesas,rcar-gen2-iic" (generic R-Car Gen2 or RZ/G1
|
|
compatible device)
|
|
- "renesas,rcar-gen3-iic" (generic R-Car Gen3 or RZ/G2
|
|
compatible device)
|
|
- "renesas,rmobile-iic" (generic device)
|
|
|
|
When compatible with a generic R-Car version, nodes
|
|
must list the SoC-specific version corresponding to
|
|
the platform first followed by the generic R-Car
|
|
version.
|
|
|
|
When compatible with "renesas,rmobile-iic" it should
|
|
be the last compatibility string listed.
|
|
|
|
The r8a77990 (R-Car E3) and r8a774c0 (RZ/G2E)
|
|
controllers are not considered compatible with
|
|
"renesas,rcar-gen3-iic" or "renesas,rmobile-iic"
|
|
due to the absence of automatic transmission registers.
|
|
|
|
- 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.
|
|
- dmas : Must contain a list of two references to DMA
|
|
specifiers, one for transmission, and one for
|
|
reception.
|
|
- dma-names : Must contain a list of two DMA names, "tx" and "rx".
|
|
|
|
|
|
Pinctrl properties might be needed, too. See there.
|
|
|
|
Example:
|
|
|
|
iic0: i2c@e6500000 {
|
|
compatible = "renesas,iic-r8a7790", "renesas,rcar-gen2-iic",
|
|
"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>;
|
|
};
