Merge tag 'pinctrl-v6.0-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "Outside the pinctrl driver and DT bindings we hit some Arm DT files,
  patched by the maintainers.

  Other than that it is business as usual.

  Core changes:

   - Add PINCTRL_PINGROUP() helper macro (and use it in the AMD driver).

  New drivers:

   - Intel Meteor Lake support.

   - Reneasas RZ/V2M and r8a779g0 (R-Car V4H).

   - AXP209 variants AXP221, AXP223 and AXP809.

   - Qualcomm MSM8909, PM8226, PMP8074 and SM6375.

   - Allwinner D1.

  Improvements:

   - Proper pin multiplexing in the AMD driver.

   - Mediatek MT8192 can use generic drive strength and pin bias, then
     fixes on top plus some I2C pin group fixes.

   - Have the Allwinner Sunplus SP7021 use the generic DT schema and
     make interrupts optional.

   - Handle Qualcomm SC7280 ADSP.

   - Handle Qualcomm MSM8916 CAMSS GP clock muxing.

   - High impedance bias on ZynqMP.

   - Serialize StarFive access to MMIO.

   - Immutable gpiochip for BCM2835, Ingenic, Qualcomm SPMI GPIO"
