[PATCH 7/8] pinctrl: at91: add registers definitions directly into driver

Nicolas Ferre nicolas.ferre at atmel.com
Tue Dec 2 09:27:27 PST 2014 

As the old gpio.c driver is gone, we can merge the registers definitions with
the pinctrl driver.
This also allows us to empty the AT91 include/mach directory.
