Merge tag 'gpio-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
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."
