[PATCH v2 0/5] Cleanup AMBA PL011 driver

[Théo Lebrun]

Hi,

While adding upstream support to a new platform (Mobileye EyeQ5[1]) that
uses the AMBA PL011 driver, I took some time to look at the PL011
driver and ended up with a few patches that cleanup parts of it. The
line-diff is big mostly because of the checkpatch-fixing commits.

The driver hadn't received any love for quite some time. A single commit
changes the code's behavior: see "tty: serial: amba-pl011: Parse bits
option as 5, 6, 7 or 8 in _get_options". See commit messages for more
information.

Compared to v1, we drop one [PATCH 6/6] & we fix some nits.

Have a nice day,

Changes in v2:
- [PATCH 2]: add #include <linux/bits.h> in include/linux/amba/serial.h
  as we use the BIT() macro.
- Move one whitespace cleanup from [PATCH 4/6] to [PATCH v2 3/5] where
  it belongs.
- Drop [PATCH 6/6]: console will never have a word length of 5 or 6.
- Link to v1: https://lore.kernel.org/r/20231026-mbly-uart-v1-0-9258eea297d3@xxxxxxxxxxx
