[PATCH v9 0/6] serial: mvebu-uart: Support for higher baudrates

From: Marek Behún
Date: Sat Feb 19 2022 - 10:28:29 EST


Hello Greg,

this is v9 of series adding support for higher baudrates on A37xx UART.

I've fixed the two things discovered in v8 (commit message typo and
order of last two patches).

Marek

Changes since v8:
* fixed typo in commit message of patch 3
* switched patches 5 and 6 as requested by Gregory Clement

Changes since v7:
* fixed lint errors in yaml binding file
* added Reviewed-by tags
* changed commit messages and comments a little
* fixed indentation at some places
* swapped patch 2 and 3 (dt-binding defining new binding should go
before the driver adding usage of that new binding)

Changes in v6:
* fixed yaml binding file and dts files

Changes in v5:
* fixed yaml binding file

Changes in v4:
* converted armada3700-uart-clock documentation to YAML
* split documentation changes into two commits:
- first which adds clock documentation
- second which updates UART documentation

Changes in v3:
v3 is rebased on top of Linus master branch and all already applied patches
were dropped. There are no changes in patches itself since v2.
