Hi Linus, here is the bulk of GPIO changes for the v3.17 cycle. This time around there is some action happening, and we will continue in v3.18. It is mostly cleanup and refactoring as Alexandre, Abdoulaye and I are working in parallell on cleanups, and then a single new driver. Please pull it in! Yours, Linus Walleij The following changes since commit 7171511eaec5bf23fb06078f59784a3a0626b38f: Linux 3.16-rc1 (2014-06-15 17:45:28 -1000) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v3.17-1 for you to fetch changes up to bdc6e95e1273b5cef01590273c1a240c53ceeea0: MAINTAINERS: update GPIO include files (2014-08-07 11:56:06 +0200) ---------------------------------------------------------------- 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. 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. ---------------------------------------------------------------- Alexandre Courbot (13): gpio: always compile label
