And it also has many interfaces such as Gbit-Ether, CAN, and USB 2.0, making it ideal for applications such as entry-class social infrastructure gateway control and industrial gateway control. This patch series adds initial SoC DTSi support for Renesas RZ/Five (R9A07G043) SoC and updates the bindings for the same. Below is the list of IP blocks added in the initial SoC DTSI which can be used to boot via initramfs on RZ/Five SMARC EVK: - AX45MP CPU - CPG - PINCTRL - PLIC - SCIF0 - SYSC Useful links: ------------- [0] https://www.renesas.com/us/en/products/microcontrollers-microprocessors/rz-mpus/rzfive-risc-v-general-purpose-microprocessors-risc-v-cpu-core-andes-ax45mp-single-10-ghz-2ch-gigabit-ethernet [1] http://www.andestech.com/en/products-solutions/andescore-processors/riscv-ax45mp/ Patch series depends on: ----------------------- [0] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20220914134211.199631-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ [1] https://patchwork.kernel.org/project/linux-renesas-soc/cover/20220915165256.352843-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ v2->v3: ------- * Re-used RZ/G2UL SMARC EVK SoM and carrier DTSI * Included RB tags * Rebased patches on -next v2: https://lore.kernel.org/all/20220815151451.23293-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ v1: https://lore.kernel.org/lkml/20220726180623.1668-5-prabhakar.mahadev-lad.rj@bp.renesas.com/ Below are the logs from RZ/Five SMARC EVK: ------------------------------------------ / # uname -ra Linux (none) 6.0.0-rc5-next-20220915-00016-g0f0153102a13 #121 SMP Thu Sep 15 16:54:44 BST 2022 riscv64 GNU/Linux / # cat /proc/cpuinfo processor : 0 hart : 0 isa : rv64imafdc mmu : sv39 uarch : andestech,ax45mp mvendorid : 0x31e marchid : 0x8000000000008a45 mimpid : 0x500 / # cat /proc/interrupts CPU0 1: 0 SiFive PLIC 412 Level 1004b800.serial:rx err 2: 0 SiFive PLIC 414 Level 1004b800.serial:rx full 3: 178 SiFive PLIC 415 Level 1004b800.serial:tx empty 4: 0 SiFive PLIC 413 Level 1004b800.serial:break 5: 1879569 RISC-V INTC 5 Edge riscv-timer 6: 37 SiFive PLIC 416 Level 1004b800.serial:rx ready IPI0: 0 Rescheduling interrupts IPI1: 0 Function call interrupts IPI2: 0 CPU stop interrupts IPI3: 0 IRQ work interrupts IPI4: 0 Timer broadcast interrupts / # cat /proc/meminfo MemTotal: 882356 kB MemFree: 861740 kB MemAvailable: 859488 kB Buffers: 0 kB Cached: 1796 kB SwapCached: 0 kB Active: 0 kB Inactive: 80 kB Active(anon): 0 kB Inactive(anon): 80 kB Active(file): 0 kB Inactive(file): 0 kB Unevictable: 1796 kB Mlocked: 0 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 116 kB Mapped: 1136 kB Shmem: 0 kB KReclaimable: 6732 kB Slab: 11932 kB SReclaimable: 6732 kB SUnreclaim: 5200 kB KernelStack: 540 kB PageTables: 32 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 441176 kB Committed_AS: 592 kB VmallocTotal: 67108864 kB VmallocUsed: 760 kB VmallocChunk: 0 kB Percpu: 84 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB Hugetlb: 0 kB / # Cheers, Prabhakar Lad Prabhakar (10): dt-bindings: soc: renesas: Move renesas.yaml from arm to soc dt-bindings: riscv: Sort the CPU core list alphabetically dt-bindings: riscv: Add Andes AX45MP core to the list dt-bindings: soc: renesas: renesas.yaml: Document Renesas RZ/Five SoC RISC-V: Kconfig.socs: Add Renesas RZ/Five SoC kconfig option riscv: dts: renesas: Add initial devicetree for Renesas RZ/Five SoC riscv: boot: dts: r9a07g043: Add placeholder nodes riscv: dts: renesas: Add minimal DTS for Renesas RZ/Five SMARC EVK MAINTAINERS: Add entry for Renesas RISC-V architecture RISC-V: configs: defconfig: Enable Renesas RZ/Five SoC .../devicetree/bindings/riscv/cpus.yaml | 11 +- .../{arm => soc/renesas}/renesas.yaml | 3 +- MAINTAINERS | 4 +- arch/riscv/Kconfig.socs | 14 + arch/riscv/boot/dts/Makefile | 1 + arch/riscv/boot/dts/renesas/Makefile | 2 + arch/riscv/boot/dts/renesas/r9a07g043.dtsi | 297 ++++++++++++++++++ .../boot/dts/renesas/r9a07g043f01-smarc.dts | 27 ++ .../boot/dts/renesas/rzfive-smarc-som.dtsi | 42 +++ arch/riscv/boot/dts/renesas/rzfive-smarc.dtsi | 56 ++++ arch/riscv/configs/defconfig | 2 + 11 files changed, 451 insertions(+), 8 deletions(-) rename Documentation/devicetree/bindings/{arm => soc/renesas}/renesas.yaml (99%) create mode 100644 arch/riscv/boot/dts/renesas/Makefile create mode 100644 arch/riscv/boot/dts/renesas/r9a07g043.dtsi create mode 100644 arch/riscv/boot/dts/renesas/r9a07g043f01-smarc.dts create mode 100644 arch/riscv/boot/dts/renesas/rzfive-smarc-som.dtsi create mode 100644 arch/riscv/boot/dts/renesas/rzfive-smarc.dtsi -- 2.25.1
