Thanks to Thomas' work TRATS can be booted today using exynos4-dt.
However, we are still missing some bits needed to make it fully functional:

 - sdhci-s3c patchset[1] is needed for eMMC support

   http://permalink.gmane.org/gmane.linux.kernel.samsung-soc/9216

 - irq-eint[2] and max8997-pmic[3] for regulators

   [2] http://permalink.gmane.org/gmane.linux.kernel.samsung-soc/8197
   [3] http://permalink.gmane.org/gmane.linux.kernel.samsung-soc/8865

These patches (created entirely by Thomas) would allow me to write
description (dts) that should cover what mach-trats.c did.

However, due to ongoing irqdomain and related changes I assume this
might take a while.

Thomas, may I ask about your plans wrt to irqdomains and wakeup/eints
(this [2] patchset)?
