Subject: [RFC 1/5] clk: iproc: define Broadcom NSP iProc clock binding

Shouldn't the device tree binding document go with the other patch
series since both the binding document and drivers are merged by Michael
or Stephen?

So the current clock driver also supports NS? That will be nice and that
indicates all the clock related registers/offsets are exactly the same
between NS and NSP?
