Hi Linus,

this is the main part of the v4.21 GPIO changes.

Details are in the signed tag.

Some interesting changes have already trickled in
through the Regulator and MMC/SD trees but get
mentioned in the signed tag nevertheless.

Please pull it in!

Yours,
Linus Walleij

The following changes since commit 651022382c7f8da46cb4872a545ee1da6d097d2a:

gpio: sama5d2-piobu: Depend on OF_GPIO (2018-12-22 11:08:06 +0100)

----------------------------------------------------------------
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.
