Linus Torvalds 24dc83635f 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. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJcJJcmAAoJEEEQszewGV1zdCoQAMSLPh+4QdYLFS3ZmnsPvZkg Zkz94RVT+uLLmHpR8XBl0wl4mmYCiwB50IwsXwlvJGceSXjCn6hLg9BZBP5hFMCb yFk3fgXQSh7TOnpjgbCWSssCjpejQ0cOb/2nWHz5s/fbYKYlh3VXckW9hhW+R+b3 6+Mno1SzmBkpVVQ21ISlZeLoNDynkCW6DfjiKMuHAyxzxa0oZ9Qid+tnVDnQM4rD rCnvYLuvxlXw97W+LI7AU9KoCITdO+2M/0dtGVEEYKfHseRReSy2Oo3nlqCglygX cNkBe9RYU1CJdas1P/c18wjDAqWp/pbugzHDkYF5Y3tBtB2rQSftjtnQngiVMXMt De7ejPvL7/OLECvI2WUD6y9NAduw/HE4FO8BBdn0gP/a9svJpVZ993yPd3F9n7EZ ZIBpycDZVtkcE7dwQgek17bFILRY5nBBMB9oCLL2wk48qdmjpcAbxVfGSsYOe6wO +cZRZuj/eR3i9gHRugfFx7Evoc7l4erihTpES/YAy3De1s3uV8KjT4zE7Jh+M9LW GM797BcXJJeb5toC7HZ/G2UAVMyWEhY0n7PGG616CS8IrzmzIZpJOL9kUVOWPb0F 9CPt6qhVbUl9rxp1H/Z3TxvYqIw6icn/z5YewZxLU1zaBlpE3jc7PhZb5hOGnFUf /DWwe4n99JsjHTrGx1ra =05LW -----END PGP SIGNATURE----- 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.
