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"
