Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.15 kernel cycle, no
  core changes at all this time, just driver work!

  New drivers:

   - New subdriver for Intel Keem Bay (an ARM-based SoC)

   - New subdriver for Qualcomm MDM9607 and SM6115

   - New subdriver for ST Microelectronics STM32MP135

   - New subdriver for Freescale i.MX8ULP ("Ultra Low Power")

   - New subdriver for Ingenic X2100

   - Support for Qualcomm PMC8180, PMC8180C, SA8155p-adp PMIC GPIO

   - Support Samsung Exynos850

   - Support Renesas RZ/G2L

  Enhancements:

   - A major refactoring of the Rockchip driver, breaking part of it out
     to a separate GPIO driver in drivers/gpio

   - Pin bias support on Renesas r8a77995

   - Add SCI pins support to Ingenic JZ4755 and JZ4760

   - Mediatek device tree bindings converted to YAML"
