New boards and systems continue to come in as new devicetree files that don't require corresponding C changes any more, which is indicating that the system is starting to work fairly well.

| * clksrc: delete nomadik MTU non-DT boot pathLinus Walleij2013-11-261-18/+5
| | | | | | | | | | | | | | | | | | | | | | | | Both platforms using the MTU (Nomadik and Ux500) have now been converted to use device tree exclusively, thus let us delete this platform data header and make this driver a fully self-contained DT-only driver.

* ARM: plat-nomadik: move MTU, kill plat-nomadikLinus Walleij2012-11-051-0/+224
This moves the MTU timer driver from arch/arm/plat-nomadik to drivers/clocksource and moves the header file to the platform_data directory. As this moves the last file being compiled to an object out of arch/arm/plat-nomadik, we have to "turn off the light" and delete the plat-nomadik directory, because it is not allowed to have an empty Makefile in a plat-* directory. This is probably also a desired side effect of depopulating the arch/arm directory of drivers. Luckily we have just deleted all the <plat/*> include files prior to this so by moving the last one we may delete the directory. After this all the Ux500 and Nomadik device drivers live outside of the arch/arm hierarchy.
