On omap4 we're missing the PowerVR SGX GPU node with it's related
"ti,hwmods" property that the SoC interconnect code needs.

Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.

I think OMAP3 & OMAP5 should also be documented and getting a
node in this series?

Looks like we don't currently have any interconnect data defined
for those, but yeah sure I can add those.

If there is anything I can test, I had modified the SGX driver for the
OMAP36, but abandoned my attempts since much of the device tree and
reset stuff was missing.  I'd love to see SGX work again.  :-)

Well the resets can be handled using platform data callbacks
for now with pdata-quirks.c. Then when the reset driver is available,
we can just remove the platform data.

And maybe push your changes to some tree so others can participate?
I'm sure the n900 users would like to see it working too.

Regards,

Tony
