Hi All, The RZ/Five microprocessor includes a RISC-V CPU Core (AX45MP Single) 1.0 GHz, 16-bit DDR3L/DDR4 interface. 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/cover/ 20220722141506.20171-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/ [1] https://patchwork.kernel.org/project/linux-renesas-soc/ cover/20220630100241.35233-1-samuel@xxxxxxxxxxxx/ [2] https://patchwork.kernel.org/project/linux-renesas-soc/patch/ 20220726174525.620-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/ [3] https://patchwork.kernel.org/project/linux-renesas-soc/patch/ 20220726174929.950-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/ [4] https://patchwork.kernel.org/project/linux-renesas-soc/patch/ 20220726175315.1147-1-prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx/ Below are the logs from Renesas RZ/Five SMARC EVK: ------------------------------------------------- / # cat /proc/cpuinfo processor : 0 hart : 0 isa : rv64imafdc mmu : sv39 uarch : andestech,ax45mp mvendorid : 0x31e marchid : 0x8000000000008a45 mimpid : 0x500 / # cat /proc/meminfo MemTotal: 884132 kB MemFree: 863292 kB MemAvailable: 860880 kB Buffers: 0 kB Cached: 1796 kB SwapCached: 0 kB Active: 1412 kB Inactive: 456 kB Active(anon): 1412 kB Inactive(anon): 456 kB Active(file): 0 kB Inactive(file): 0 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 108 kB Mapped: 1136 kB Shmem: 1796 kB KReclaimable: 6424 kB Slab: 12548 kB SReclaimable: 6424 kB SUnreclaim: 6124 kB KernelStack: 844 kB PageTables: 32 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 442064 kB Committed_AS: 2388 kB VmallocTotal: 67108864 kB VmallocUsed: 860 kB VmallocChunk: 0 kB Percpu: 84 kB CmaTotal: 0 kB CmaFree: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB Hugetlb: 0 kB / # / # cat /proc/interrupts CPU0 1: 0 SiFive PLIC 412 Level 1004b800.serial:rx err 2: 1 SiFive PLIC 414 Level 1004b800.serial:rx full 3: 72 SiFive PLIC 415 Level 1004b800.serial:tx empty 4: 0 SiFive PLIC 413 Level 1004b800.serial:break 5: 10193 RISC-V INTC 5 Edge riscv-timer 6: 14 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 / # / # for i in machine family soc_id revision; do echo -n "$i: ";cat /sys/devices/ soc0/$i; done machine: Renesas SMARC EVK based on r9a07g043 family: RZ/Five soc_id: r9a07g043 revision: 0 / # Cheers, Prabhakar Lad Prabhakar (6): dt-bindings: arm: renesas: Ignore the schema for RISC-V arch dt-bindings: riscv: Sort the CPU core list alphabetically dt-bindings: riscv: Add Andes AX45MP core to the list dt-bindings: riscv: Add DT binding documentation for Renesas RZ/Five SoC and SMARC EVK RISC-V: Kconfig.socs: Add Renesas RZ/Five SoC kconfig option riscv: dts: renesas: Add initial devicetree for Renesas RZ/Five SoC .../devicetree/bindings/arm/renesas.yaml | 9 ++ .../devicetree/bindings/riscv/cpus.yaml | 11 +- .../devicetree/bindings/riscv/renesas.yaml | 49 +++++++ arch/riscv/Kconfig.socs | 14 ++ arch/riscv/boot/dts/Makefile | 1 + arch/riscv/boot/dts/renesas/r9a07g043.dtsi | 121 ++++++++++++++++++ 6 files changed, 200 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/riscv/renesas.yaml create mode 100644 arch/riscv/boot/dts/renesas/r9a07g043.dtsi -- 2.17.1
