Merge tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO changes from Linus Walleij: "This is the bulk of GPIO changes for the v3.18 development cycle: - Increase the default ARCH_NR_GPIO from 256 to 512. This was done to avoid having a custom <asm/gpio.h> header for the x86 architecture - GPIO is custom and complicated enough as it is already! We want to move to a radix to store the descriptors going forward, and finally get rid of this fixed array size altogether. - Endgame patching of the gpio_remove() semantics initiated by Abdoulaye Berthe. It is not accepted by the system that the removal of a GPIO chip fails during eg reboot or shutdown, and therefore the return value has now painfully been refactored away. For special cases like GPIO expanders on a hot-pluggable bus like USB, we may later add some gpiochip_try_remove() call, but for the cases we have now, return values are moot. - Some incremental refactoring of the gpiolib core and ACPI GPIO library for more descriptor usage. - Refactor the chained IRQ handler set-up method to handle also threaded, nested interrupts and set up the parent IRQ correctly. Switch STMPE and TC3589x drivers to use this registration method. - Add a .irq_not_threaded flag to the struct gpio_chip, so that also GPIO expanders that block but are still not using threaded IRQ handlers. - New drivers for the ARM64 X-Gene SoC GPIO controller. - The syscon GPIO driver has been improved to handle the "DSP GPIO" found on the TI Keystone 2 SoC:s. - ADNP driver switched to use gpiolib irqchip helpers. - Refactor the DWAPB driver to support being instantiated from and MFD cell (platform device). - Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP, Xilinx and Crystalcove drivers. - Various minor fixes" * tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (52 commits) gpio: pch: Build context save/restore only for PM pinctrl: abx500: get rid of unused variable gpio: ks8695: fix 'else should follow close brace '}'' gpio: stmpe: add verbose debug code gpio: stmpe: fix up interrupt enable logic gpio: staticize xway_stp_init() gpio: handle also nested irqchips in the chained handler set-up gpio: set parent irq on chained handlers gpiolib: irqchip: use irq_find_mapping while removing irqchip gpio: crystalcove: support virtual GPIO pinctrl: bcm281xx: make Kconfig dependency more strict gpio: kona: enable only on BCM_MOBILE or for compile testing gpio, bcm-kona, LLVMLinux: Remove use of __initconst gpio: Fix ngpio in gpio-xilinx driver gpio: dwapb: fix pointer to integer cast gpio: xgene: Remove unneeded #ifdef CONFIG_OF guard gpio: xgene: Remove unneeded forward declation for struct xgene_gpio gpio: xgene: Fix missing spin_lock_init() gpio: ks8695: fix switch case indentation gpiolib: add irq_not_threaded flag to gpio_chip ...
