- Rewrite the interaction with the GPIO subsystem - the pin
controller descriptor now handles this by defining an offset into the GPIO numberspace for its handled pin range. This is used to look up the apropriate pin controller for a GPIO pin. Then that specific GPIO range is matched 1-1 for the target controller instance.

Linus Walleij (4): drivers: create a pinmux subsystem v4 pinmux: add a driver for the U300 pinmux amba: request muxing for PrimeCell devices mach-u300: activate pinmux driver, delete old padmux driver
it seems there is not an actual example that gpio requests pin from pinctrl yet. i might give one on SiRFprimaII.
Thanks Barry
