Merge tag 'intel-gpio-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/andy/linux-gpio-intel into devel
intel-gpio for v5.5-1
* Prerequisite patch against GPIO library to register pin ranges in time.
* Second attempt to fix Intel Merrifield GPIO driver to utilize irqchip.
The following is an automated git shortlog grouped by driver:
gpiolib:
- Introduce ->add_pin_ranges() callback
merrifield:
- Pass irqchip when adding gpiochip
- Add GPIO <-> pin mapping ranges via callback
