This series adds a serial driver, with console support, for the UART IP block present on the SiFive FU540 SoC. The programming model is straightforward, but unique. Boot-tested on a SiFive FU540 HiFive-U board (with appropriate patches to the DT data). The patches in this series can also be found at: https://github.com/sifive/riscv-linux/tree/dev/paulw/serial-v4.19-rc7 - Paul Paul Walmsley (2): dt-bindings: serial: add documentation for the SiFive UART driver tty: serial: add driver for the SiFive UART .../bindings/serial/sifive-serial.txt | 21 + drivers/tty/serial/Kconfig | 24 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/sifive.c | 1070 +++++++++++++++++ include/uapi/linux/serial_core.h | 3 + 5 files changed, 1119 insertions(+) create mode 100644 Documentation/devicetree/bindings/serial/sifive-serial.txt create mode 100644 drivers/tty/serial/sifive.c vmlinux size difference (from v4.19-rc7): text data bss dec hex filename +2528 -2008 +64 +584 +248 vmlinux -- 2.19.1
