GPIO changes for v3.6:

- 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.

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
