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"
