Merge tag 'gpio-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.21 kernel series.

  Core changes:

   - Some core changes are already in outside of this pull request as
     they came through the regulator tree, most notably
     devm_gpiod_unhinge() that removes devres refcount management from a
     GPIO descriptor. This is needed in subsystems such as regulators
     where the regulator core need to take over the reference counting
     and lifecycle management for a GPIO descriptor.

   - We dropped devm_gpiochip_remove() and devm_gpio_chip_match() as
     nothing needs it. We can bring it back if need be.

   - Add a global TODO so people see where we are going. This helps
     setting the direction now that we are two GPIO maintainers.

   - Handle the MMC CD/WP properties in the device tree core. (The bulk
     of patches activating this code is already merged through the
     MMC/SD tree.)

   - Augment gpiochip_request_own_desc() to pass a flag so we as
     gpiochips can request lines as active low or open drain etc even
     from ourselves.

  New drivers:

   - New driver for Cadence GPIO blocks.

   - New driver for Atmel SAMA5D2 PIOBU GPIO lines.

  Driver improvements:

   - A major refactoring of the PCA953x driver - this driver has been
     around for ages, and is now modernized to reduce code duplication
     that has stacked up and is using regmap to read write and cache
     registers.

   - Intel drivers are now maintained in a separate tree and start with
     a round of cleanups and unifications"
