Merge tag 'gpio-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij: "Here is the bulk of GPIO changes for the v4.4 development cycle. The only changes hitting outside drivers/gpio are in the pin control subsystem and these seem to have settled nicely in linux-next. Development mistakes and catfights are nicely documented in the reverts as you can see. The outcome of the ABI fight is that we're working on a chardev ABI for GPIO now, where hope to show results for the v4.5 kernel. Summary of changes: GPIO core: - Define and handle flags for open drain/open collector and open source/open emitter, also know as "single-ended" configurations. - Generic request/free operations that handle calling out to the (optional) pin control backend. - Some refactoring related to an ABI change that did not happen, yet provide useful. - Added a real-time compliance checklist. Many GPIO chips have irqchips, and need to think this over with the RT patches going upstream. - Restructure, fix and clean up Kconfig menus a bit. New drivers: - New driver for AMD Promony. - New driver for ACCES 104-IDIO-16, a port-mapped I/O card, ISA-style. Very retro. Subdriver changes: - OMAP changes to handle real time requirements. - Handle trigger types for edge and level IRQs on PL061 properly. As this hardware is very common it needs to set a proper example for others to follow. - Some container_of() cleanups. - Delete the unused MSM driver in favor of the driver that is embedded inside the pin control driver. - Cleanup of the ath79 GPIO driver used by many, many OpenWRT router targets. - A consolidated IT87xx driver replacing the earlier very specific IT8761e driver. - Handle the TI TCA9539 in the PCA953x driver. Also handle ACPI devices in this subdriver. - Drop xilinx arch dependencies as these FPGAs seem to profilate over a few different architectures. MIPS and ARM come to mind" * tag 'gpio-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (57 commits) gpio: fix up SPI submenu gpio: drop surplus I2C dependencies gpio: drop surplus X86 dependencies gpio: dt-bindings: document the official use of "ngpios" gpio: MAINTAINERS: Add an entry for the ATH79 GPIO driver gpio / ACPI: Allow shared GPIO event to be read via operation region gpio: group port-mapped I/O drivers in a menu gpio: Add ACCES 104-IDIO-16 driver maintainer entry gpio: zynq: Document interrupt-controller DT binding gpio: xilinx: Drop architecture dependencies gpio: generic: Revert to old error handling in bgpio_map gpio: add a real time compliance notes Revert "gpio: add a real time compliance checklist" gpio: Add GPIO support for the ACCES 104-IDIO-16 gpio: driver for AMD Promontory gpio: xlp: Convert to use gpiolib irqchip helpers gpio: add a real time compliance checklist gpio/xilinx: enable for MIPS gpiolib: Add and use OF_GPIO_SINGLE_ENDED flag gpiolib: Split GPIO flags parsing and GPIO configuration ...
