Merge tag 'pinctrl-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "We have no core changes but lots of incremental development in drivers
  all over the place: Renesas, NXP, Mediatek and Actions Semiconductor
  keep churning out new SoCs.

  I have some subtree maintainers for Renesas and Intel helping out to
  keep down the load, it's been working smoothly (Samsung also have a
  subtree but it was not used this cycle.)

  New drivers:

   - NXP (ex Freescale) i.MX 8 QXP SoC driver.

   - Mediatek MT6797 SoC driver.

   - Mediatek MT7629 SoC driver.

   - Actions Semiconductor S700 SoC driver.

   - Renesas RZ/A2 SoC driver.

   - Allwinner sunxi suniv F1C100 SoC driver.

   - Qualcomm PMS405 PMIC driver.

   - Microsemi Ocelot Jaguar2 SoC driver.

  Improvements:

   - Some RT improvements (using raw spinlocks where appropriate).

   - A lot of new pin sets on the Renesas PFC pin controllers.

   - GPIO hogs now work on the Qualcomm SPMI/SSBI pin controller GPIO
     chips, and Xway.

   - Major modernization of the Intel pin control drivers.

   - STM32 pin control driver will now synchronize usage of pins with
     another CPU using a hardware spinlock"
