Merge tag 'intel-gpio-v6.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/andy/linux-gpio-intel into gpio/for-next

intel-gpio for v6.4-2

* Fixed suspend issue on Clevo NL5xNU
* Split a new Intel Tangier (library) driver for current and new platforms
* Introduced a new driver for Intel Elkhart Lake PSE GPIO (see also above)
* Contained a few fixes for the previous of_gpio.h cleanup
* Miscellaneous cleanups here and there

The following is an automated git shortlog grouped by driver:

elkhartlake:
 -  Introduce Intel Elkhart Lake PSE GPIO

gpiolib:
 -  acpi: Add a ignore wakeup quirk for Clevo NL5xNU
 -  acpi: Move ACPI device NULL check to acpi_get_driver_gpio_data()
 -  acpi: use the fwnode in acpi_gpiochip_find()

ich:
 -  Use devm_gpiochip_add_data() to simplify remove path

merrifield:
 -  Utilise temporary variable for struct device
 -  Use dev_err_probe()
 -  Adapt to Intel Tangier GPIO driver

mips:
 -  ar7: include linux/gpio/driver.h

mm-lantiq:
 -  Fix typo in the newly added header filename

powerpc/40x:
 -  Add missing select OF_GPIO_MM_GPIOCHIP

sh:
 -  mach-x3proto: Add missing #include <linux/gpio/driver.h>

tangier:
 -  Introduce Intel Tangier GPIO driver
