cycle, and this time we got a lot of action going on and it will continue: - The core GPIO library implementation has been split up in three different files: - gpiolib.c for the latest and greatest and shiny GPIO library code using GPIO descriptors only - gpiolib-legacy.c for the old integer number space API that we are phasing out gradually - gpiolib-sysfs.c for the sysfs interface that we are not entirely happy with, but has to live on for ABI compatibility - Add a flags argument to *gpiod_get* functions, with some backward-compatibility macros to ease transitions. We should have had the flags there from the beginning it seems, now we need to clean up the mess. There is a plan on how to move forward here devised by Alexandre Courbot and Mark Brown. - Split off a special <linux/gpio/machine.h> header for the board gpio table registration, as per example from the regulator subsystem. - Start to kill off the return value from gpiochip_remove() by removing the __must_check attribute and removing all checks inside the drivers/gpio directory. The rationale is: well what were we supposed to do if there is an error code? Not much: print an error message. And gpiolib already does that. So make this function return void eventually. - Some cleanups of hairy gpiolib code, make some functions not to be used outside the library private and make sure they are not exported, remove gpiod_lock/unlock_as_irq() as the existing function is for driver-internal use and fine as it is, delete gpio_ensure_requested() as it is not meaningful anymore. - Support the GPIOF_ACTIVE_LOW flag from gpio_request_one() function calls, which is logical since this is already supported when referencing GPIOs from e.g. device trees. - Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use the gpiolib irqchip helpers cutting down on GPIO irqchip boilerplate a bit more. - New driver for the Zynq GPIO block. - The usual incremental improvements around a bunch of drivers. - Janitorial syntactic and semantic cleanups by Jingoo Han, and Rickard Strandqvist especially. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJT5Ji9AAoJEEEQszewGV1zch8QAKp67+8ScxRBf/7RCSV6U/dy i7kt+nP4au/TScwtjbX264DM8hroW7BzN+GqF10NEFeGkYDR+42lMav9PrNjtKtk ojQPWdoGWzwwL0wa4j9rsuG/pRnbAEgDWPb+EkFdHQsLl6h71fyVoLOK+gKwJFyn aPYGXyNbT1FN38oj1rarENiOUxM7VMXvcJFfvDYFdDDhCS4PLYPOMw0lrsGtsHMZ epDa4z3yt4zHgYiUIT578nQ7EkIbGN3goywk3NQ+9WDQG+sLFHh4BdqcRKg6b9VM I64+47uNQxkyvWCvcLma5ziqvtNQk113986g+cv5YeTh18Ajyio1kxEIZM181eBk ITUPGrAorWHPLGNbe3psLmtK3+/BwmWIurPmHpckuW8d2JWWSVe0oepkUuqDwu/w lUB5KtM0joFOr5k61fj5tCKxH344jc1zvHJ/N+bVYilbOMvunWzuMJlc4hADIGC2 1uxUAcPbYUAphGaxhdMBca9ellm0lWG19Gj5TtdGbRtNgp6R2qrwI66DDzk+1kLR 8Szx6KHQdEHFTlCLKSIAMv33p1ClfmNikhdicT3urwR8PeXmmTR1pD7kGmVTDDZa gXSU5EilgGpak+77j/GZ2Ivp0Qt5M97UwWlZ7zTp++T1ZY+wwTHJI/09qcoWYjdz IpZRIqrQchalbscpn3LY =e+d6 -----END PGP SIGNATURE----- Merge tag 'gpio-v3.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO update from Linus Walleij: "This is the bulk of GPIO changes for the v3.17 development cycle, and this time we got a lot of action going on and it will continue: - The core GPIO library implementation has been split up in three different files: - gpiolib.c for the latest and greatest and shiny GPIO library code using GPIO descriptors only - gpiolib-legacy.c for the old integer number space API that we are phasing out gradually - gpiolib-sysfs.c for the sysfs interface that we are not entirely happy with, but has to live on for ABI compatibility - Add a flags argument to *gpiod_get* functions, with some backward-compatibility macros to ease transitions.
