It's not a staging driver. Rui's focus appears to be to have this
driver accepted into Mainline by hook or by crock. He's tried MFD,
Misc and now Staging!

Background:

There are a number of drivers in this family which currently reside in
MFD. These were accepted before my time. After a recent review I've
made the decision that these aren't MFD drivers at all.

MFD drivers are ones which aid in registering and setting up shared
resources for sub-devices which reside on the same piece of silicon.
This driver does basically none of that. Instead it *is* the (what we
describe above as) sub-device. It does everything.

In the absence of a subsystem which covers this type of device, I
suggested Misk as a good location to place these drivers.
