[PATCH 0/4] gpio: hierarchical IRQ improvements

[Brian Masney <masneyb@xxxxxxxxxxxxx>]

This builds on top of Linus Walleij's existing patches that adds
hierarchical IRQ support to the GPIO core [1] so that Qualcomm's
spmi-gpio and ssbi-gpio can be converted to use these new helpers.

Linus: Feel free to squash these into your existing patches if you'd
like to use any of this code. Just give me some kind of mention in the
commit description.

    functions
  gpio: allow customizing hierarchical IRQ chips
  gpio: use handler in gpio_irq_chip instead of handle_bad_irq
  qcom: spmi-gpio: convert to hierarchical IRQ helpers in gpio core
