Pull pin control updates from Linus Walleij:
 "Nothing special, notably a lot of new Qualcomm hardware is supported,
  a RISC-V reference SoC and then some cleanups both in code and device
  tree bindings.

  Core changes:

   - Add PINCTRL_PINFUNCTION() macro and use it in several drivers

  New drivers:

   - New driver for the StarFive JH7110 SoC "sys" and "aon" (always-on)
     pin controllers. (RISC-V.)

   - New subdriver for the Qualcomm QDU1000/QRU1000 SoC pin controller

   - New subdrivers for the Qualcomm SM8550 SoC and LPASS pin
     controllers

   - New subdriver for the Qualcomm SA8775P SoC pin controller

   - New subdriver for the Qualcomm IPQ5332 SoC pin controller

   - New (trivial) support for Qualcomm PM8550 and PMR735D PMIC pin
     control

   - New subdriver for the Mediatek MT7981 SoC pin controller

  Improvements:

   - Several cleanups and refactorings to the Intel drivers

   - Add 4KOhm bias support to the Intel driver

   - Use the NOIRQ_SYSTEM_SLEEP_PM_OPS for the AT91 driver

   - Support general purpose clocks in the Qualcomm MSM8226 SoC

   - Several conversions to use the new I2C .probe_new() call

   - Massive clean-up of the Qualcomm Device Tree YAML schemas

   - Add VIN[45] pins, groups and functions to the Renesas r8a77950 SoC
     driver"

The of_gpio_n_cells default is 2 when ->of_xlate() callback is
not defined. No need to assign it explicitly in the driver.

sppctl_gpio_inv_get is only used from the debugfs code inside
of an #ifdef, so we get a warning without that:

drivers/pinctrl/sunplus/sppctl.c:393:12: error: 'sppctl_gpio_inv_get' defined but not used [-Werror=unused-function]
  393 | static int sppctl_gpio_inv_get(struct gpio_chip *chip, unsigned int offset)
      |            ^~~~~~~~~~~~~~~~~~~

Replace the #ifdef with an IS_ENABLED() check that avoids the warning.

As the potential failure of the kcalloc(),
it should be better to check it in order to
avoid the dereference of the NULL pointer.
