1 Device tree configuration for Renesas RIIC driver 2 3 Required properties: 4 - compatible : "renesas,riic-<soctype>". "renesas,riic-rz" as fallback 5 - reg : address start and address range size of device 6 - interrupts : 8 interrupts (TEI, RI, TI, SPI, STI, NAKI, ALI, TMOI) 7 - clock-frequency : frequency of bus clock in Hz 8 - #address-cells : should be <1> 9 - #size-cells : should be <0> 10 11 Pinctrl properties might be needed, too. See there. 12 13 Example: 14 15 i2c0: i2c@fcfee000 { 16 compatible = "renesas,riic-r7s72100", "renesas,riic-rz"; 17 reg = <0xfcfee000 0x44>; 18 interrupts = <0 157 IRQ_TYPE_LEVEL_HIGH>, 19 <0 158 IRQ_TYPE_EDGE_RISING>, 20 <0 159 IRQ_TYPE_EDGE_RISING>, 21 <0 160 IRQ_TYPE_LEVEL_HIGH>, 22 <0 161 IRQ_TYPE_LEVEL_HIGH>, 23 <0 162 IRQ_TYPE_LEVEL_HIGH>, 24 <0 163 IRQ_TYPE_LEVEL_HIGH>, 25 <0 164 IRQ_TYPE_LEVEL_HIGH>; 26 clock-frequency = <100000>; 27 #address-cells = <1>; 28 #size-cells = <0>; 29 };
