Btw, I don't know if it affects omap2/3, but I'm making a change with
the dss hwmod devices so that the dss_core will be a parent device to
all the other dss hwmod devices. This solves the mess on omap4, the
modulemode bit, and the sequence in which the dss clocks need to be
enabled, as dss_core will always be enabled first.

This requires two patches for omap_device, "ARM: OMAP: remove
omap_device_parent", "ARM: OMAP: omap_device: Expose omap_device_{alloc,
delete, register}" which I hope are going in in the next merge window.

So, it may not affect omap2/3 in any way, but just thought to mention.
