Subject: [PATCH v2 0/5] Generalize OF gpio support code

This series makes all gpio drivers usable from the OF support apis by
automatically registering a default OF translator when the of_node
pointer is assigned.  These patches are heavily based on the work that
Anton did earlier, but I didn't add the notifiers infrastructure and
the OF data now lives directly inside the core gpio_chip structure so
that fewer gymnastics are needed to get at it.

These patches are currently sitting in the following branch:

git://git.secretlab.ca/git/linux-2.6 next-devicetree

Anton Vorontsov (3):
      gpiolib: cosmetic improvements for error handling in gpiochip_add()
      of/gpio: Kill of_gpio_chip and add members directly to gpio_chip
      of/gpio: add default of_xlate function if device has a node pointer

Grant Likely (2):
      of/gpio: stop using device_node data pointer to find gpio_chip
      of/device: Add OF style matching helper function
