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 This third version updates the DT binding documentation per discussion with Rob Herring and fixes one additional issue identified by the 0-day build system related to MODULE_DEVICE_TABLE.
