>
> This adds a driver for the U300 pinmux portions of the system
> controller "SYSCON". It also serves as an example of how to use
> the pinmux subsystem. This driver also houses the platform data
> for the only supported platform.
>
> This deletes the old U300 driver in arch/arm/mach-u300 and
> replace it with a driver using the new subsystem.
>
> The new driver is considerably fatter than the old one, but it
> also registers all 467 pins of the system and adds the power
> and EMIF pin groups and corresponding functions. The idea
> is to use this driver as a a reference for other
> implementation so it needs to be as complete and verbose
> as possible.

> Signed-off-by: Linus Walleij <linus.walleij at linaro.org>
