  Summary:

   - new testing module: gpio-sim that is scheduled to replace
     gpio-mockup

   - initial changes aiming at converting all GPIO drivers to using the

     gpiolib-of.c

   - add support for Tegra234 and Tegra241 to gpio-tegra186

   - add support for new models (SSD201 and SSD202D) to gpio-msc313

   - add basic support for interrupts to gpio-aggregator

   - add support for AMDIF031 HID device to gpio-amdpt

   - drop support for unused platforms in gpio-xlp

   - cleanup leftovers from the removal of the legacy Samsung Exynos
     GPIO driver

   - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make
     PREEMPT_RT happy

   - generalize the common 'ngpios' device property by reading it in the
     core gpiolib code so that we can remove duplicate reads from
     drivers

   - allow line names from device properties to override names set by
     drivers

   - code shrink in gpiod_add_lookup_table()

   - add new model to the DT bindings for gpio-vf610

   - convert DT bindings for tegra devices to YAML

   - improvements to interrupt handling in gpio-rcar and gpio-rockchip

   - updates to intel drivers from Andy (details in the merge commit)

   - some minor tweaks, improvements and coding-style fixes all around
     the subsystem"
