Merge tag 'pinctrl-v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "Core changes:

   - NONE whatsoever, we don't even touch the core files this time
     around.

  New drivers:

   - New driver for the Toshiba Visconti SoC.

   - New subdriver for the Qualcomm MSM8226 SoC.

   - New subdriver for the Actions Semiconductor S500 SoC.

   - New subdriver for the Mediatek MT8192 SoC.

   - New subdriver for the Microchip SAMA7G5 SoC.

  Driver enhancements:

   - Intel Cherryview and Baytrail cleanups and refactorings.

   - Enhanced support for the Renesas R8A7790, more pins and groups.

   - Some optimizations for the MCP23S08 MCP23x17 variant.

   - Some cleanups around the Actions Semiconductor subdrivers.

   - A bunch of cleanups around the SH-PFC and Emma Mobile drivers.

   - The "SH-PFC" (literally SuperH pin function controller, I think)
     subdirectory is now renamed to the more neutral "renesas", as these
     are not very much centered around SuperH anymore.

   - Non-critical fixes for the Aspeed driver.

   - Non-critical fixes for the Ingenic (MIPS!) driver.

   - Fix a bunch of missing pins on the AMD pinctrl driver"
