Merge tag 'pinctrl-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.11 kernel.

  Drivers, drivers and drivers. Not a single core change.

  Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
  SoCs.

  As part of the modularization attempt, I applied one patch affecting
  the firmware subsystem as a functional (not syntactic/semantic)
  dependency and then it blew up in our face, so I had to revert it,
  bummer. It will come in later, through that subsystem, I guess.

  New drivers:

   - New driver for the Microchip Serial GPIO "SGPIO".

   - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

  New subdrivers:

   - Intel Lakefield subdriver.

   - Intel Elkhart Lake subdriver.

   - Intel Alder Lake-S subdriver.

   - Qualcomm MSM8953 subdriver.

   - Qualcomm SDX55 subdriver.

   - Qualcomm SDX55 PMIC subdriver.

   - Ocelot Luton SoC subdriver.

   - Ocelot Serval SoC subdriver.

  Modularization:

   - The Meson driver can now be built as modules.

   - The Qualcomm driver(s) can now be built as modules.

  Incremental improvements:

   - The Intel driver now supports pin configuration for GPIO-related
     configurations.

   - A bunch of Renesas PFC drivers have been augmented with support for
     QSPI pins, groups and functions.

   - Non-critical fixes to the irq handling in the Allwinner Sunxi
     driver"
