The bug fixes in this series look good in general. I have provided my
design comments in the previous RFC thread [1] still, since the overall
changes here are not that much different from the RFC.

Thanks for prototyping the OMAP portions, it demonstrates the adaptation
to the new API, but I have to take a step approach in moving the current
OMAP mailbox code and making incremental changes on top of it. The
mailbox driver is the bottom-most layer in our IPC stacks, so changes at
this layer are very critical to the functional behavior.

Suman
