Device tree configuration for Renesas RIIC driver
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible :
|
||
|
|
"renesas,riic-r7s72100" if the device is a part of a R7S72100 SoC.
|
||
|
|
"renesas,riic-r7s9210" if the device is a part of a R7S9210 SoC.
|
||
|
|
"renesas,riic-rz" for a generic RZ/A compatible device.
|
||
|
|
- reg : address start and address range size of device
|
||
|
|
- interrupts : 8 interrupts (TEI, RI, TI, SPI, STI, NAKI, ALI, TMOI)
|
||
|
|
- clock-frequency : frequency of bus clock in Hz
|
||
|
|
- #address-cells : should be <1>
|
||
|
|
- #size-cells : should be <0>
|
||
|
|
|
||
|
|
Pinctrl properties might be needed, too. See there.

||

Example:
|
||
|
|
|
||
|
|
i2c0: i2c@fcfee000 {
|
||
|
|
compatible = "renesas,riic-r7s72100", "renesas,riic-rz";
|
||
|
|
reg = <0xfcfee000 0x44>;
|
||
|
|
interrupts = <0 157 IRQ_TYPE_LEVEL_HIGH>,
|
||
|
|
<0 158 IRQ_TYPE_EDGE_RISING>,
|
||
|
|
<0 159 IRQ_TYPE_EDGE_RISING>,
|
||
|
|
<0 160 IRQ_TYPE_LEVEL_HIGH>,
|
||
|
|
<0 161 IRQ_TYPE_LEVEL_HIGH>,
|
||
|
|
<0 162 IRQ_TYPE_LEVEL_HIGH>,
|
||
|
|
<0 163 IRQ_TYPE_LEVEL_HIGH>,
|
||
|
|
<0 164 IRQ_TYPE_LEVEL_HIGH>;
|
||
|
|
clock-frequency = <100000>;
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
};
