Well, I wrote the binding for it:-)

There are at least a couple of different things in this file:

a) The reset API, which definitely should be converted to the new reset
API. I can't make any promises about which kernel release that will
happen in, but it's definitely something we know we have to do.

b) Power-gating. This should probably be converted to use the
powerdomains code. I believe Joseph Lo is aware of this, but again I
can't promise any specific time-scale at this time.

So is this still OK, without any promises of timescale?
