Hi Linus, there is quite a lot going on in the GPIO subsystem this merge window, so the main matter is decribed in the signed tag. The hits in other subsystems when making the GPIO flags optional are all ACKed by their respective subsystem maintainers. The development cycle was a bit rough, I had to merge in -rc4 to get rid of some conflicts and revert a patch that was messing up a later patch. Watch out if you get merge conflicts (tested on your HEAD earlier and it worked fine, but you never know). Please pull this in! Yours, Linus Walleij The following changes since commit cbfe8fa6cd672011c755c3cd85c9ffd4e2d10a6f: Linux 4.2-rc4 (2015-07-26 12:26:21 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v4.3-1 for you to fetch changes up to 01e2dae991771adb1257eb5cd3cecfda1aa09ba9: Revert "gpio: extraxfs: fix returnvar.cocci warnings" (2015-08-31 08:56:04 +0200) ---------------------------------------------------------------- This is the bulk of GPIO changes for the v4.3 kernel cycle: Core changes: - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions of the descriptor calls that did not use the flags argument on the end. This was around for too long and eventually Uwe Kleine-König took the time to clean it out and the last users are removed along with the macros in this tag. In several cases the use of flags simplifies the code. For this reason we have (ACKed) patches hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the nail with removing the macros. - Add a fat document describing how much ready-made GPIO stuff we have i the kernel to discourage people from reinventing a square wheel in userspace, as so often happens. - Create a separate lockdep class for each instance of a GPIO IRQ chip instead of using one class for all chips, as the current code will not work with systems with several GPIO chips doing lockdep debugging. - Protect against driver unloading also when a GPIO line is only used as IRQ for the GPIOLIB_IRQCHIP helpers. - If the GPIO chip has no designated owner, assign the parent device driver owner as owner. - Consolidation of chained IRQ handler install/remove replacing all call sites where irq_set_handler_data() and irq_set_chained_handler() were done in succession with a combined call to irq_set_chained_handler_and_data(). This series was created by Thomas Gleixner after the problem was observed by Russell King. - Tglx also made another series of patches switching __irq_set_handler_locked() for irq_set_handler_locked() which is way cleaner. - Tglx and Jiang Liu wrote a good bunch of patches to make use of irq_desc_get_xxx() accessors and avoid looking up irq_descs from IRQ numbers. The goal is to get rid of the irq number from the handlers in the IRQ flow which is nice. - Rob Herring killed off the set_irq_flags() for all GPIO drivers. This was an ARM specific function that is replaced with the generic irq_modify_status() where special flags are actually needed. - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER if the pin controller isn't available. Pretty logical, yet needed to be fixed. - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call back, then call these instead of the defaults provided by the GPIOLIB. - Fix an undocumented ABI hole: named GPIOs were not properly documented. Driver improvements: - Add get_direction() support to the generic GPIO driver, it's strange that we didn't have that before. - Make it possible to have input-only GPIO chips using the generic GPIO driver. - Clean out platform data support from the Emma Mobile (EM) driver - Finegrained runtime PM support for the RCAR driver. - Support r8a7795 (R-car H3) in the RCAR driver. - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver. - Some consolidation and new support in the MPC8xxx driver, we now support MPC5125. - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw spinlocks making it work better with the realime patches. - Interrupt support for the EXTRAXFS GPIO driver. - Make the ETRAXFS GPIO driver support also ARTPEC-3. - Interrupt and wakeup support for the BRCMSTB driver, also for wakeup from S5 cold boot. - Mask MXC IRQs during suspend. - Improve OMAP2 GPIO set_debounce() to work according to spec. - The VF610 driver handles IRQs properly. New drivers: - ZTE ZX GPIO driver. ---------------------------------------------------------------- Alexander Stein (1): gpio: mpc8xxx: Convert mpc8xxx_gpio_chip.lock to raw_spinlock Alexandre Courbot
