Subject: [PATCH 0/7] gpio: assorted irqdomain cleanups

I have noted that some of the GPIO drivers have been copy-pasting
and contaminating each other with bad examples, so I've tried in
this series to mitigate this by correcting the most obvious
examples.

I have no clue how to even compile-test some of these, so I rely
on maintainers to test them and maybe refactor them up if they are
sucky.

Remains: gpio-omap, gpio-pxa and gpio-twl4030.

These three drivers do *REALLY* scary stuff, like creating domains
and flat out ignoring to use them, keeping the irq_base after
allocating descriptors around and abusing it etc. I would really
like to see these fixed up to use irqdomains properly. The
twl4030 looks really hairy with the IRQ handling centralized
into the main MFD driver...

Linus Walleij (7):
  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/mxs: convert to use linear irqdomain
  gpio/pcf857x: find the irq domain mapping
  gpio/langwell: find the irq domain mapping
  gpio/tegra: convert to use linear irqdomain
