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" * tag 'gpio-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (99 commits) gpio: sama5d2-piobu: Depend on OF_GPIO gpio: Add Cadence GPIO driver dt-bindings: gpio: Add bindings for Cadence GPIO gpiolib-acpi: remove unused variable 'err', cleans up build warning gpio: mxs: read pin level directly instead of using .get gpio: aspeed: remove duplicated statement gpio: add driver for SAMA5D2 PIOBU pins dt-bindings: arm: atmel: describe SECUMOD usage as a GPIO controller gpio/mmc/of: Respect polarity in the device tree dt-bindings: gpio: rcar: Add r8a774c0 (RZ/G2E) support memory: omap-gpmc: Get the header of the enum ARM: omap1: Fix new user of gpiochip_request_own_desc() gpio: pca953x: Add regmap dependency for PCA953x driver gpio: raspberrypi-exp: decrease refcount on firmware dt node gpiolib: Fix return value of gpio_to_desc() stub if !GPIOLIB gpio: pca953x: Restore registers after suspend/resume cycle gpio: pca953x: Zap single use of pca953x_read_single() gpio: pca953x: Zap ad-hoc reg_output cache gpio: pca953x: Zap ad-hoc reg_direction cache gpio: pca953x: Perform basic regmap conversion ...
