[PATCH v3 0/2] tty: serial: add DT bindings and serial driver for the SiFive FU540 UART

[Paul Walmsley]

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

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.
