Hi Linus, this is the bulk of GPIO changes for the v3.15 merge window. Note: - This tree has pulled in an immutable branch with some irqchip infrastructure from Thomas Gleixner. This stuff is already in your tree coming in from tip. However as this pull request is based on v3.14-rc6 you will still see the commits in this pull request, but it should be all right. (Else beat me up as usual.) I tested to pull it in on top of your master and it LooksGoodToMe(TM) - Some changes hit the pin control tree, but have been funneled through this one tree to avoid fuzz and conflicts. A pretty big chunk of changes this time, but it has all been on rotation in linux-next and had some testing. Of course there will be some amount of fixes on top... The rest of the story is in the signed tag. Please pull it in! Yours, Linus Walleij The following changes since commit fa389e220254c69ffae0d403eac4146171062d08: Linux 3.14-rc6 (2014-03-09 19:41:57 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v3.15-1 for you to fetch changes up to b22978fc33dec72e5f8e17f90eb63ea9137aafd5: gpio: rcar: Add helper variable dev = &pdev->dev (2014-03-28 21:54:41 +0100) ---------------------------------------------------------------- This is the bulk of GPIO changes for v3.15: - Merged in a branch of irqchip changes from Thomas Gleixner: we need to have new callbacks from the irqchip to determine if the GPIO line will be eligible for IRQs, and this callback must be able to say "no". After some thinking I got the branch from tglx and have switched all current users over to use this. - Based on tglx patches, we have added some generic irqchip helpers in the gpiolib core. These will help centralize code when GPIO drivers have simple chained/cascaded IRQs. Drivers will still define their irqchip vtables, but the gpiolib core will take care of irqdomain set-up, mapping from local offsets to Linux irqs, and reserve resources by marking the GPIO lines for IRQs. - Initially the PL061 and Nomadik GPIO/pin control drivers have been switched over to use the new gpiochip-to-irqchip infrastructure with more drivers expected for the next kernel cycle. The factoring of just two drivers still makes it worth it so it is already a win. - A new driver for the Synopsys DesignWare APB GPIO block. - Modify the DaVinci GPIO driver to be reusable also for the new TI Keystone architecture. - A new driver for the LSI ZEVIO SoCs. - Delete the obsolte tnetv107x driver. - Some incremental work on GPIO descriptors: have gpiod_direction_output() use a logical level, respecting assertion polarity through ACTIVE_LOW flags, adding gpiod_direction_output_raw() for the case where you want to set that very value. Add gpiochip_get_desc() to fetch a GPIO descriptor from a specific offset on a certain chip inside driver code. - Switch ACPI GPIO code over to using gpiochip_get_desc() and get rid of gpio_to_desc(). - The ACPI GPIO event handling code has been reworked after encountering an actual real life implementation. - Support for ACPI GPIO operation regions. - Generic GPIO chips can now be assigned labels/names from platform data. - We now clamp values returned from GPIO drivers to the boolean [0,1] range. - Some improved documentation on how to use the polarity flag was added. - The a large slew of incremental driver updates and non-critical fixes. Some targeted for stable. ---------------------------------------------------------------- Aaron Sierra (4): gpio: pca953x: Add devices to Kconfig help gpio: pca953x: Add NXP PCA9698 gpio: pca953x: Add Exar XRA1202 gpio: pca953x: Fix gpio_base may not default to -1 Alan Tull (2): fix build error in gpio-dwapb patch gpio: gpio-dwapb size-cells should be two Alexander Holler (1): gpio: davinci: fix gpio selection for OF Alexander Shiyan (6): gpio: davinci: Use signed type for 'irq' variable gpio: rc5t583: Remove redundant check gpio: generic: Use platform_device_id->driver_data field for driver flags gpio: Driver for SYSCON-based GPIOs gpio: twl4030: Remove redundant assignment gpio: samsung: Add missing "break" statement Alexandre Courbot (3): gpiolib: add gpiochip_get_desc() driver function gpiolib: ACPI: remove gpio_to_desc() usage gpio: clamp returned values to the boolean range Arnd Bergmann (1): gpio: remove obsolete tnetv107x driver Axel Lin (4): gpio: pl061: Select IRQ_DOMAIN rather than GENERIC_IRQ_CHIP gpio: clps711x: Add missing .owner to struct gpio_chip gpio: moxart: Avoid forward declaration gpio: moxart: Actually set output state in moxart_gpio_direction_output() Bartlomiej Zolnierkiewicz (1): gpio: iop: fix devm_ioremap_resource() return value checking Daniel Krueger (1): pch_gpio: set value before enabling output direction David Cohen (1): gpio: intel-mid: comments cleanup Fabian Vogt (1): gpio: New driver for LSI ZEVIO SoCs Fabio Estevam (1): gpio: gpio-pl061: Use %pa to print 'resource_size_t' Gary Servin (1): gpio: mcp23s08: trivial: fixed coding style issues Geert Uytterhoeven (2): gpio: Spelling s/than/that/ gpio: rcar: Add helper variable dev = &pdev->dev Grygorii Strashko (1): gpio: davinci: reuse for keystone soc James Hogan (1): gpio-tz1090: Replace commas with semi-colons Jamie Iles (1): gpio: add a driver for the Synopsys DesignWare APB GPIO block Jean Delvare (2): gpio-ts5500: Add dependency gpio: cs5535: Simplify dependencies Jean-Francois Dagenais (3): gpio: adp5588: get value from data out when dir is out gpio: adp5588 -
