Hi Linus,
this is my major GPIO pull request for the v3.7 merge window.
The description of what's going on is in the tag (see below).
I think some of it is prerequisites for the ARM SoC tree so better
send this pull early.
All has boiled in -next for some time except the 4 topmost
commits, which are oneline fixes (would else be -rc material)
and a documentation fix.
Please pull it in!
Yours,
Linus Walleij

gpio: pcf857x: select IRQ_DOMAIN (2012-09-30 23:38:53 +0200)
----------------------------------------------------------------
So this is the LW GPIO patch stack for v3.7:
- refactoring from Thierry Redding at Arnd Bergmann's request to use
the seq_file iterator interface in gpiolib.
- A new driver for Avionic Design's N-bit GPIO expander.
- Two instances of mutexes replaced by spinlocks from Axel Lin to
code that is supposed to be fastpath compliant.
- IRQ demuxer and gpio_to_irq() support for pcf857x by Kuninori
Morimoto.
- Dynamic GPIO numbers, device tree support, daisy chaining and some
other fixes for the 74x164 driver by Maxime Ripard.
- IRQ domain and device tree support for the tc3589x driver by
Lee Jones.
- Some conversion to use managed resources devm_* code.
- Some instances of clk_prepare() or clk_prepare_enable() added to
support the new, stricter common clock framework.
- Some for_each_set_bit() simplifications.
- Then a lot of fixes as we fixed up all of the above tripping over
our own shoelaces and that kind of thing.
