Merge tag 'gpio-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO changes from Linus Walleij:
- New driver for AMD-8111 southbridge GPIOs
- New driver for Wolfson Micro Arizona devices
- Propagate device tree parse errors
- Probe deferral finalizations - all expected calls to GPIO will now
hopefully request deferral where apropriate
- Misc updates to TCA6424, WM8994, LPC32xx, PCF857x, Samsung MXC, OMAP
and PCA953X drivers.
Fix up gpio_idx conflicts in drivers/gpio/gpio-mxc.c
