Add the i3c controller devices to the ast2600 g6 common dts. We add all 6 busses to the common g6 definition, but leave disabled through the status property, to be enabled per-platform. Suggested-by: Jeremy Kerr <[email protected]> Signed-off-by: Dawid Glazik <[email protected]> --- v4: - removed i3c aliases - renamed i3c-global node name to generic: syscon v3: - add i3c aliases - rebase on top of latest tree and solve conflicts - as agreed with Jeremy off-list, he said I can take authorship of this going forward v2: - use inline bus representation, without the i3c: label --- arch/arm/boot/dts/aspeed/aspeed-g6.dtsi | 91 +++++++++++++++++++++++++ 1 file changed, 91 insertions(+) diff --git a/arch/arm/boot/dts/aspeed/aspeed-g6.dtsi b/arch/arm/boot/dts/aspeed/aspeed-g6.dtsi index f5641128614f..51a6a4157f1b 100644 --- a/arch/arm/boot/dts/aspeed/aspeed-g6.dtsi +++ b/arch/arm/boot/dts/aspeed/aspeed-g6.dtsi @@ -1066,6 +1066,97 @@ i2c15: i2c@800 { }; }; + bus@1e7a0000 { + compatible = "simple-bus"; + #address-cells = <1>; + #size-cells = <1>; + ranges = <0 0x1e7a0000 0x8000>; + + i3c_global: syscon@0 { + compatible = "aspeed,ast2600-i3c-global", "syscon"; + reg = <0x0 0x1000>; + resets = <&syscon ASPEED_RESET_I3C_DMA>; + }; + + i3c0: i3c@2000 { + compatible = "aspeed,ast2600-i3c"; + reg = <0x2000 0x1000>; + #address-cells = <3>; + #size-cells = <0>; + clocks = <&syscon ASPEED_CLK_GATE_I3C0CLK>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_i3c1_default>; + interrupts = <GIC_SPI 102 IRQ_TYPE_LEVEL_HIGH>; + aspeed,global-regs = <&i3c_global 0>; + status = "disabled"; + }; + + i3c1: i3c@3000 { + compatible = "aspeed,ast2600-i3c"; + reg = <0x3000 0x1000>; + #address-cells = <3>; + #size-cells = <0>; + clocks = <&syscon ASPEED_CLK_GATE_I3C1CLK>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_i3c2_default>; + interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>; + aspeed,global-regs = <&i3c_global 1>; + status = "disabled"; + }; + + i3c2: i3c@4000 { + compatible = "aspeed,ast2600-i3c"; + reg = <0x4000 0x1000>; + #address-cells = <3>; + #size-cells = <0>; + clocks = <&syscon ASPEED_CLK_GATE_I3C2CLK>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_i3c3_default>; + interrupts = <GIC_SPI 104 IRQ_TYPE_LEVEL_HIGH>; + aspeed,global-regs = <&i3c_global 2>; + status = "disabled"; + }; + + i3c3: i3c@5000 { + compatible = "aspeed,ast2600-i3c"; + reg = <0x5000 0x1000>; + #address-cells = <3>; + #size-cells = <0>; + clocks = <&syscon ASPEED_CLK_GATE_I3C3CLK>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_i3c4_default>; + interrupts = <GIC_SPI 105 IRQ_TYPE_LEVEL_HIGH>; + aspeed,global-regs = <&i3c_global 3>; + status = "disabled"; + }; + + i3c4: i3c@6000 { + compatible = "aspeed,ast2600-i3c"; + reg = <0x6000 0x1000>; + #address-cells = <3>; + #size-cells = <0>; + clocks = <&syscon ASPEED_CLK_GATE_I3C4CLK>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_i3c5_default>; + interrupts = <GIC_SPI 106 IRQ_TYPE_LEVEL_HIGH>; + aspeed,global-regs = <&i3c_global 4>; + status = "disabled"; + }; + + i3c5: i3c@7000 { + compatible = "aspeed,ast2600-i3c"; + reg = <0x7000 0x1000>; + #address-cells = <3>; + #size-cells = <0>; + clocks = <&syscon ASPEED_CLK_GATE_I3C5CLK>; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_i3c6_default>; + interrupts = <GIC_SPI 107 IRQ_TYPE_LEVEL_HIGH>; + aspeed,global-regs = <&i3c_global 5>; + status = "disabled"; + }; + }; + fsim0: fsi@1e79b000 { #interrupt-cells = <1>; compatible = "aspeed,ast2600-fsi-master"; -- 2.43.0
