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.
