I'm fine with this appproach. For both patches:

Reviewed-by: Kevin Hilman <khilman@xxxxxxxxxx>

Also, I gave it a spin across a handful of OMAP boards using v3.12-rc2 +
these 2 patches.

Boot tested successfully with DT boot:

omap3530/beagle
omap3730/beagle-xm
omap3530/overo (Tobi w/GPIO IRQ networking)
omap3730/overo STORM (w/GPIO IRQ for networking)
am335x/beaglebone
am335x/beaglebone black
omap4430/panda
omap4460/panda-es
omap5912/OSK (omap1)

I also verified non-DT boot on the OMAP3 platforms that still support
legacy boot.

So feel free to also add

Thanks for your persistence in getting a fix for this upstream.
