Merge tag 'gpio-v3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO changes from Linus Walleij: "This is the GPIO bulk changes for the v3.20 series: GPIOLIB core changes: - Create and use of_mm_gpiochip_remove() for removing memory-mapped OF GPIO chips - GPIO MMIO library suppports bgpio_set_multiple for switching several lines at once, a feature merged in the last cycle. New drivers: - New driver for the APM X-gene standby GPIO controller - New driver for the Fujitsu MB86S7x GPIO controller Cleanups: - Moved rcar driver to use gpiolib irqchip - Moxart converted to the GPIO MMIO library - GE driver converted to GPIO MMIO library - Move sx150x to irqdomain - Move max732x to irqdomain - Move vx855 to use managed resources - Move dwapb to use managed resources - Clean tc3589x from platform data - Clean stmpe driver to use device tree only probe New subtypes: - sx1506 support in the sx150x driver - Quark 1000 SoC support in the SCH driver - Support X86 in the Xilinx driver - Support PXA1928 in the PXA driver Extended drivers: - max732x supports device tree probe - sx150x supports device tree probe Various minor cleanups and bug fixes" * tag 'gpio-v3.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (61 commits) gpio: kconfig: replace PPC_OF with PPC gpio: pxa: add PXA1928 gpio type support dt/bindings: gpio: add compatible string for marvell,pxa1928-gpio gpio: pxa: remove mach IRQ includes gpio: max732x: use an inline function for container cast gpio: use sizeof() instead of hardcoded values gpio: max732x: add set_multiple function gpio: sch: Consolidate similar algorithms gpio: tz1090-pdc: Use resource_size to fix off-by-one resource size calculation gpio: ge: Convert to use devm_kstrdup gpio: correctly use const char * const gpio: sx150x: fixup OF support gpio: mpc8xxx: Use of_mm_gpiochip_remove gpio: Add Fujitsu MB86S7x GPIO driver gpio: mpc8xxx: Convert to platform device interface. gpio: zevio: Use of_mm_gpiochip_remove gpio: gpio-mm-lantiq: Use of_mm_gpiochip_remove gpio: gpio-mm-lantiq: Use of_property_read_u32 gpio: gpio-mm-lantiq: Do not replicate code gpio :gpio-mm-lantiq: Use devm_kzalloc ...
