Change since v1:
        * Fix coding style issue.
	* Register gpio clocks with CLKDEV_DEV_ID instead of CLKDEV_CON_DEV_ID

This patchset add atmel pinctrl/gpio driver and the corresponding clocks for
the at91sam9g45 device.

The pinctrl driver also include the gpio driver (like in linux) because the gpio and pinctrl parts share same structures.

This driver is based on mach-at91/gpio.c and linux pinctrl driver.
The driver contains the gpio and pinctrl parts (like in linux) because the two parts
share some structures and logics.

We already have all these functions in arch/arm/mach-at91/gpio.h. Do we
really need them twice? Can't we use a single header file?

Hi,

I can add all the functions from mach-at91/gpio.h in
mach-at91/include/gpio.h and remove mach-at91/gpio.h. Is this a valid
solution ?
