Merge branch 'depends/gpio-devel' into next/soc
This is required for some of the clps711x series, so we're bringing in
the dependency explicitly.
By Linus Walleij (5) and others
via Linus Walleij
* depends/gpio-devel:
GPIO: clps711x: use platform_device_unregister in gpio_clps711x_init()
gpio/tc3589x: convert to use the simple irqdomain
gpio/em: convert to linear IRQ domain
gpio/mvebu: convert to use irq_domain_add_simple()
gpio/tegra: convert to use linear irqdomain
gpiolib: unlock on error in gpio_export()
gpiolib: add gpio get direction callback support
GPIO: clps711x: Fix direction logic for PORTD
GPIO: clps711x: Fix return value for gpio_clps711x_get
gpiolib: Refactor gpio_export
GPIO: vt8500: Add extended gpio bank for WM8505/WM8650
gpio: clps711x: delete local <mach/gpio.h> header
GPIO: Add support for GPIO on CLPS711X-target platform
DA9055 GPIO driver
gpio/gpio-omap: Use existing pointer to struct device
gpio/gpio-pl061: Covert to use devm_* functions
