Hi Linus, I guess this can go into your desired "next" branch for v3.16 where we start landing changes for the v3.16 merge window this week if I understand your message correctly. There is a lot of action in the GPIO subsystem doing refactorings and cleanups, almost as many deletions as insertions and minor feature growth and no new drivers this time. Which is actually pretty nice. Some GPIO-related stuff will come in through the pin control tree as well. I merged in v3.15-rc4 at one time to get rid of nasty conmflicts in -next. Fine-grained details in the signed tag as usual. The below is well tested in linux-next and should be in real nice shape (famous last words), so please pull it in. Yours, Linus Walleij The following changes since commit 89ca3b881987f5a4be4c5dbaa7f0df12bbdde2fd: Linux 3.15-rc4 (2014-05-04 18:14:42 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v3.16-1 for you to fetch changes up to fc346270124a1a05a5b3c47f277d467ff410b3ae: gpio: select IRQ_DOMAIN for gpiolib irqchip helpers (2014-05-29 16:52:46 +0200) ---------------------------------------------------------------- This is the bulk of GPIO changes for the v3.16 series: - We are finalizing and fixing up the gpiochip irqchip helpers bringing a helpful irqchip implementation into the gpiolib core and avoiding duplicate code and, more importantly, duplicate bug fixes: - Support for using the helpers with threaded interrupt handlers as used on sleeping GPIO-irqchips - Do not set up hardware triggers for edges or levels if the default IRQ type is IRQ_TYPE_NONE - some drivers would exploit the fact that you could get default initialization of the IRQ type from the core at probe() but if no default type is set up from the helper, we should not call the driver to configure anything. Wait until a consumer requests the interrupt instead. - Make the irqchip helpers put the GPIO irqs into their own lock class. The GPIO irqchips can often emit (harmless, but annoying) lockdep warnings about recursions when they are in fact just cascaded IRQs. By putting them into their own lock class we help the lockdep core to keep track of things. - Switch the tc3589x GPIO expanders to use the irqchip helpers - Switch the OMAP GPIO driver to use the irqchip helpers - Add some documentation for the irqchip helpers - select IRQ_DOMAIN when using the helpers since some platforms may not be using this by default and it's a strict dependency. - Continued GPIO descriptor refactoring: - Remove the one instance of gpio_to_desc() from the device tree code, making the OF GPIO code use GPIO descriptors only. - Introduce gpiod_get_optional() and gpiod_get_optional_index() akin to the similar regulator functions for cases where the use of GPIO is optional and not strictly required. - Make of_get_named_gpiod_flags() private - we do not want to unnecessarily expose APIs to drivers that make the gpiolib harder than necessary to maintain and refactor. Privatize this function. - Support "-gpio" suffix for the OF GPIO retrieveal path. We used to look for "foo-gpios" or just "gpios" in device tree nodes, but it turns out that some drivers with a single GPIO line will just state "foo-gpio" (singularis). Sigh. Support this with a fallback looking for it, as this simplifies driver code and handles it in core code. - Switch the ACPI GPIO core to fetch GPIOs with the *_cansleep function variants as the GPIO operation region handler can sleep, and shall be able to handle gpiochips that sleep. - Tons of cleanups and janitorial work from Jingoo Han, Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe. Notably Jingoo cut off a ton of pointless OOM messages. - Incremental development and fixes for various drivers, nothing really special here.
