Add initial device tree for Renesas RZ/Five RISC-V CPU Core (AX45MP Single). RZ/Five SoC is almost identical to RZ/G2UL Type-1 SoC (ARM64) hence we will be reusing r9a07g043.dtsi [0] as a base DTSI for both the SoC's. r9a07g043f.dtsi includes RZ/Five SoC specific blocks. Below are the RZ/Five SoC specific blocks added in the initial DTSI which can be used to boot via initramfs on RZ/Five SMARC EVK: - AX45MP CPU - PLIC [0] arch/arm64/boot/dts/renesas/r9a07g043.dtsi Signed-off-by: Lad Prabhakar Reviewed-by: Conor Dooley Acked-by: Palmer Dabbelt Link: https://lore.kernel.org/r/20221028165921.94487-5-prabhakar.mahadev-lad.rj@bp.renesas.com Signed-off-by: Geert Uytterhoeven Signed-off-by: Lad Prabhakar Reviewed-by: Nobuhiro Iwamatsu --- arch/riscv/boot/dts/renesas/r9a07g043f.dtsi | 57 +++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 arch/riscv/boot/dts/renesas/r9a07g043f.dtsi diff --git a/arch/riscv/boot/dts/renesas/r9a07g043f.dtsi b/arch/riscv/boot/dts/renesas/r9a07g043f.dtsi new file mode 100644 index 0000000000000..50134be548f53 --- /dev/null +++ b/arch/riscv/boot/dts/renesas/r9a07g043f.dtsi @@ -0,0 +1,57 @@ +// SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +/* + * Device Tree Source for the RZ/Five SoC + * + * Copyright (C) 2022 Renesas Electronics Corp. + */ + +#include + +#define SOC_PERIPHERAL_IRQ(nr) (nr + 32) + +#include + +/ { + cpus { + #address-cells = <1>; + #size-cells = <0>; + timebase-frequency = <12000000>; + + cpu0: cpu@0 { + compatible = "andestech,ax45mp", "riscv"; + device_type = "cpu"; + reg = <0x0>; + status = "okay"; + riscv,isa = "rv64imafdc"; + mmu-type = "riscv,sv39"; + i-cache-size = <0x8000>; + i-cache-line-size = <0x40>; + d-cache-size = <0x8000>; + d-cache-line-size = <0x40>; + clocks = <&cpg CPG_CORE R9A07G043_CLK_I>; + + cpu0_intc: interrupt-controller { + #interrupt-cells = <1>; + compatible = "riscv,cpu-intc"; + interrupt-controller; + }; + }; + }; +}; + +&soc { + interrupt-parent = <&plic>; + + plic: interrupt-controller@12c00000 { + compatible = "renesas,r9a07g043-plic", "andestech,nceplic100"; + #interrupt-cells = <2>; + #address-cells = <0>; + riscv,ndev = <511>; + interrupt-controller; + reg = <0x0 0x12c00000 0 0x400000>; + clocks = <&cpg CPG_MOD R9A07G043_NCEPLIC_ACLK>; + power-domains = <&cpg>; + resets = <&cpg R9A07G043_NCEPLIC_ARESETN>; + interrupts-extended = <&cpu0_intc 11 &cpu0_intc 9>; + }; +};
