[RFC/PATCH 0/2] Updates to improve device tree support

This patch series updates the pca953x GPIO driver to take advantage
of the new of_i2c_gpiochip_add() function, which registers i2c GPIO
devices with the device tree API.  These changes allow i2c-based GPIO
expanders to be properly referenced from the proper entries in a
device tree.

The of_i2c_gpiochip_add() function has been posted for review on the
linuxppc-dev mailing list.

Bill Gatliff (2):
  Use struct of_i2c_gpio_chip instead of raw struct gpio_chip
  Reorder initialization to better support device tree data
