Pull GPIO changes from Linus Walleij:
 "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."
