The programming model is straightforward, but unique. Boot-tested on a SiFive FU540 HiFive-U board, using BBL and the open-source FSBL (with appropriate patches to the DT data). This fifth version fixes a bug in the set_termios handler, found by Andreas Schwab . The patches in this series can also be found, with the PRCI patches, DT patches, and DT prerequisite patch, at: https://github.com/sifive/riscv-linux/tree/dev/paulw/serial-v5.1-rc4 - 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 | 33 + drivers/tty/serial/Kconfig | 24 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/sifive.c | 1056 +++++++++++++++++ include/uapi/linux/serial_core.h | 3 + 5 files changed, 1117 insertions(+) create mode 100644 Documentation/devicetree/bindings/serial/sifive-serial.txt create mode 100644 drivers/tty/serial/sifive.c -- 2.20.1
