Merge tag 'intel-gpio-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/andy/linux-gpio-intel into devel

intel-gpio for v5.9-1

* Move GPIO PMIC drivers to use IRQ chip template
* Introduce for_each_requested_gpio() and convert existing users
* Replace unsigned by unsigned int in few drivers
* Fix an issue in kernel doc that validator complains about
* Move to verbose debug level the IRQ status message in gpio-pch

The following is an automated git shortlog grouped by driver:

ARM/orion/gpio:
 -  Make use of for_each_requested_gpio()

crystalcove:
 -  Use irqchip template
 -  changed every 'unsigned' to 'unsigned int'

gpiolib:
 -  Introduce for_each_requested_gpio_in_range() macro

gpio-ml-ioh:
 -  Fix missing ':' in 'struct ioh_gpio_reg_data

ich:
 -  changed every 'unsigned' to 'unsigned int'

mvebu:
 -  Make use of for_each_requested_gpio()

pch:
 -  Add a blank line between declaration and code
 -  changed every 'unsigned' to 'unsigned int'
 -  Move IRQ status message to verbose debug level

pinctrl:
 -  at91: Make use of for_each_requested_gpio()

sch:
 -  Add a blank line between declaration and code
 -  changed every 'unsigned' to 'unsigned int'

wcove:
 -  Use irqchip template

xra1403:
 -  Make use of for_each_requested_gpio()
