Merge tag 'gpio-v4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio 

Pull GPIO fixes from Linus Walleij:

 - LP87565: set the proper output level for direction_output.

 - stm32: fix the kernel build by selecting the hierarchical irqdomain
   symbol properly - this happens to be done in the pin control
   framework but whatever, it had dependencies to GPIO so we need to
   apply it here.

 - Select the hierarchical IRQ domain also for Xgene.

 - Fix wakeups to work on MXC.

 - Fix up the device tree binding on Exar that went astray, also add the
   right bindings.

 - Fix the unwanted events for edges from the library.

 - Fix the unbalanced chanined IRQ on the Tegra.

* tag 'gpio-v4.13-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  gpio: tegra: fix unbalanced chained_irq_enter/exit
  gpiolib: skip unwanted events, don't convert them to opposite edge
  gpio: exar: Use correct property prefix and document bindings
  gpio: gpio-mxc: Fix: higher 16 GPIOs usable as wake source
  gpio: xgene-sb: select IRQ_DOMAIN_HIERARCHY
  pinctrl: stm32: select IRQ_DOMAIN_HIERARCHY instead of depends on
  gpio: lp87565: Set proper output level and direction for direction_output
