Merge tag 'pinctrl-v6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"No core changes this time around.
New drivers:
- New driver for Renesas R8A779H0 also known as R-Car V4M.
- New driver for the Awinic AW9523/B I2C GPIO expander. I found this
living out-of-tree in OpenWrt as an upstream attempt had stalled on
the finishing line, so I picked it up and finished the job.
Improvements:
- The Nomadik pin control driver was for years re-used out of tree
for the ST STA chips, and now the IP was re-used in a MIPS
automotive SoC called MobilEyeq5, so it has been split in pin
control and GPIO drivers so the latter can be reused by MobilEyeq5.
(Along with a long list of cleanups)
- A lot of overall cleanup and tidying up"
