Merge tag 'gpio-updates-for-v5.13-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Browse Source 
Pull gpio updates from Bartosz Golaszewski:

 - new driver for the Realtek Otto GPIO controller

 - ACPI support for gpio-mpc8xxx

 - edge event support for gpio-sch (+ Kconfig fixes)

 - Kconfig improvements in gpio-ich

 - fixes to older issues in gpio-mockup

 - ACPI quirk for ignoring EC wakeups on Dell Venue 10 Pro 5055

 - improve the GPIO aggregator code by using more generic interfaces
   instead of reimplementing them in the driver

 - convert the DT bindings for gpio-74x164 to yaml

 - documentation improvements

 - a slew of other minor fixes and improvements to GPIO drivers

gpio_mockup_ranges
This parameter takes an argument in the form of an array of integer
pairs. Each pair defines the base GPIO number (if any) and the number
of lines exposed by the chip. If the base GPIO is -1, the gpiolib
will assign it automatically.
pairs. Each pair defines the base GPIO number (non-negative integer)
and the first number after the last of this chip. If the base GPIO
is -1, the gpiolib will assign it automatically. while the following
parameter is the number of lines exposed by the chip.
Example: gpio_mockup_ranges=-1,8,-1,16,405,4
Example: gpio_mockup_ranges=-1,8,-1,16,405,409
The line above creates three chips. The first one will expose 8 lines,
the second 16 and the third 4. The base GPIO for the third chip is set
to 405 while for two first chips it will be assigned automatically.
gpio_named_lines
gpio_mockup_named_lines
This parameter doesn't take any arguments. It lets the driver know that
GPIO lines exposed by it should be named.
