Subject: [PATCH v2 0/2] tty: serial: add DT bindings and serial driver for the SiFive FU540 UART

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 second version fixes a few problems identified by the 0-day
build system, mostly focused around remnants relating to
CONFIG_CONSOLE_POLL, and a missing spin_unlock() in the ISR.
