Hi Linus, here is the bulk of GPIO changes for the v4.19 kernel cycle. I don't know if anything in particular stands out. Maybe the Aspeed coprocessor thing from Benji: Aspeed is doing baseboard management chips (BMC's) for servers etc. These Aspeed's are ARM processors that exist inside (I guess) Intel servers, and they are moving forward to using mainline Linux in those. This is one of the pieces of the puzzle to achive that. They are doing OpenBMC, it's pretty cool. https://lwn.net/Articles/683320/ The other details are in the signed tag. Please pull it in! Yours, Linus Walleij The following changes since commit ce397d215ccd07b8ae3f71db689aedb85d56ab40: Linux 4.18-rc1 (2018-06-17 08:04:49 +0900) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v4.19-1 for you to fetch changes up to a5ec96ddfd55c501d451cb310566a1170c267ecb: gpio: it87: Add support for IT8613 (2018-08-10 23:19:17 +0200) ---------------------------------------------------------------- This is the bulk of GPIO changes for the v4.19 kernel cycle: Core changes: - Add a new API for explicitly naming GPIO consumers, when needed. - Don't let userspace set values on input lines. While we do not think anyone would do this crazy thing we better plug the hole before someone uses it and think it's a nifty feature. - Avoid calling chip->request() for unused GPIOs. New drivers/subdrivers: - The Mediatek MT7621 is supported which is a big win for OpenWRT and similar router distributions using this chip, as it seems every major router manufacturer on the planet has made products using this chip: https://wikidevi.com/wiki/MediaTek_MT7621 - The Tegra 194 is now supported. - The IT87 driver now supports IT8786E and IT8718F super-IO chips. - Add support for Rockchip RK3328 in the syscon GPIO driver. Driver changes: - Handle the get/set_multiple() properly on MMIO chips with inverted direction registers. We didn't have this problem until a new chip appear that has get/set registers AND inverted direction bits, OK now we handle it. - A patch series making more error codes percolate upward properly for different errors on gpiochip_lock_as_irq(). - Get/set multiple for the OMAP driver, accelerating these multiple line operations if possible. - A coprocessor interface for the Aspeed driver. Sometimes a few GPIO lines need to be grabbed by a co-processor for doing automated tasks, sometimes they are available as GPIO lines. By adding an explicit API in this driver we make it possible for the two line consumers to coexist. (This work was made available on the ib-aspeed branch, which may be appearing in other pull requests.) - Implemented .get_direction() and open drain in the SCH311x driver. - Continuing cleanup of included headers in GPIO drivers. ---------------------------------------------------------------- Andy Shevchenko (13): gpiolib: Join string literals back gpiolib: Respect error code of ->get_direction() gpiolib: Mark gpio_suffixes array with __maybe_unused gpiolib: Consistent use of ->get_direction() inside gpiolib gpiolib: Join one line back for better readability gpiolib: Use GPIOD_OUT_{LOW,HIGH} macros in open drain ones gpiolib: Don't shadow error code of gpiochip_lock_as_irq() gpio: bcm-kona: Don't shadow error code of gpiochip_lock_as_irq() gpio: dwapb: Don't shadow error code of gpiochip_lock_as_irq() gpio: em: Don't shadow error code of gpiochip_lock_as_irq() gpio: xgene-sb: Don't shadow error code of gpiochip_lock_as_irq() gpio: uniphier: Bail out on gpiochip_lock_as_irq() error gpio: vr41xx: Bail out on gpiochip_lock_as_irq() error Anson Huang (2): gpio: mxc: Add clocks optional binding for imx gpio gpio: mxc: add power management support Anton Vasilyev (1): gpio: ml-ioh: Fix buffer underwrite on probe error path Arnd Bergmann (2): gpio: aspeed: fix compile testing warning gpio: mt7621: add OF_GPIO dependency Bartosz Golaszewski (2): gpiolib: don't allow userspace to set values of input lines gpiolib: remove an unnecessary TODO Baruch Siach (1): gpio: pca953x: suppress interrupts warning when not applicable Benjamin Herrenschmidt (4): gpio: aspeed: Rework register type accessors gpio: aspeed: Add "Read Data" register to read the write latch gpio: aspeed: Add command source registers gpio: aspeed: Add interfaces for co-processor to grab GPIOs Biju Das (2): gpiolib: Fix of_node inconsistency gpiolib: Avoid calling chip->request() for unused gpios Daniel Mack (1): gpio: pxa: disable pinctrl calls for PXA3xx Dmitry Osipenko (1): gpio: tegra: Fix tegra_gpio_irq_set_type() Fabio Estevam (1): gpio: mxs: Fit writel() into a single line Geert Uytterhoeven (2): w1: Allow compile test of GPIO consumers if !GPIOLIB gpio: rcar: Implement .get_direction() callback Ivan Podovalov (1): gpio: it87: add support for IT8718F Super I/O.
