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>; |
|
};
