Since v2: - fix dt_binding_check and dtbs_check warnings - use uart_port_tx_limited() helper in uart driver - collect Acked-by/Reviewed-by tag - uart0 -> uart3 - update "riscv,ndev" property - mv vendor prefix binding as the first patch - add compatible string for bouffalolab bl808 plic Since v1: - use FIELD_PREP and FIELD_GET macro - rewrite bflb_uart_tx_chars() - add vendor prefix for bouffalolab - add dt binding for bl808 compatibles - enable SOC_BOUFFALOLAB in defconfig - collect Reviewed-by tag - modify commit-msg as suggested Jisheng Zhang (10): dt-bindings: vendor-prefixes: add bouffalolab dt-bindings: interrupt-controller: Add bouffalolab bl808 plic dt-bindings: serial: add documentation for Bouffalolab UART Driver serial: bflb_uart: add Bouffalolab UART Driver riscv: add the Bouffalolab SoC family Kconfig option dt-bindings: riscv: Add bouffalolab bl808 board compatibles riscv: dts: bouffalolab: add the bl808 SoC base device tree riscv: dts: bouffalolab: add Sipeed M1s SoM and Dock devicetree MAINTAINERS: riscv: add entry for Bouffalolab SoC riscv: defconfig: enable BOUFFALOLAB SoC .../sifive,plic-1.0.0.yaml | 1 + .../bindings/riscv/bouffalolab.yaml | 29 + .../serial/bouffalolab,bl808-uart.yaml | 47 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 7 + arch/riscv/Kconfig.socs | 5 + arch/riscv/boot/dts/Makefile | 1 + arch/riscv/boot/dts/bouffalolab/Makefile | 2 + .../dts/bouffalolab/bl808-sipeed-m1s-dock.dts | 25 + .../dts/bouffalolab/bl808-sipeed-m1s.dtsi | 21 + arch/riscv/boot/dts/bouffalolab/bl808.dtsi | 73 +++ arch/riscv/configs/defconfig | 1 + drivers/tty/serial/Kconfig | 18 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/bflb_uart.c | 586 ++++++++++++++++++ include/uapi/linux/serial_core.h | 3 + 16 files changed, 822 insertions(+) create mode 100644 Documentation/devicetree/bindings/riscv/bouffalolab.yaml create mode 100644 Documentation/devicetree/bindings/serial/bouffalolab,bl808-uart.yaml create mode 100644 arch/riscv/boot/dts/bouffalolab/Makefile create mode 100644 arch/riscv/boot/dts/bouffalolab/bl808-sipeed-m1s-dock.dts create mode 100644 arch/riscv/boot/dts/bouffalolab/bl808-sipeed-m1s.dtsi create mode 100644 arch/riscv/boot/dts/bouffalolab/bl808.dtsi create mode 100644 drivers/tty/serial/bflb_uart.c
