v2 heads up: I didn't ignore Krzysztof's request to squash some commits,
I wasn't sure what to squash and I thought since I've fixed everything now
it was better to send a v2 sooner than later.

I've now fixed all of the warnings except one remaining one that seems to
need a change in dt-schema itself to cleanup:

serial@221000 (ns16550a): reg-shift: 3 is not one of [0, 1, 2]
        from schema $id: http://devicetree.org/schemas/reg.yaml

The way registers are connected in these chips is weird. I think
they took their peripheral block from an 8051 microcontroller
and jammed it onto 32bit CPUs so all of the registers have
weird spacing and it really does need reg-shift == 3.

v1 blurb:
    
I saw a slide at LPC that had sigmastar in the "hall of shame"
for DT warnings. I finally got some time to look at this so
I have fixed the ones that are obvious and quick to fix.

I'll fix the rest but they might take a bit longer i.e. one
of them is about the register shift for the UART registers,
that'll need the binding to be updated I think?

FWIW this platform isn't dead and I have been rebasing all
of the out of tree stuff that make it useful (Audio support,
display, hardware video decoding etc) but its basically stuck
on rewriting the clock driver so that it is mainline-able.

Some other people have taken the limited support in mainline
and my out of tree stuff and made it run on old MStar MIPS
machines too..

change log:

v2:
 - Fix the regulator names as suggested by Krzysztof
 - Adjust the opp table name                
 - Add a commit to fix the cpupll binding and clean up the         
   warnings for that
 - Add a commit to fix the memory node in the infinity2m 
   dtsi to fix up the warnings about that.
 - Add a commit to switch the default led trigger on breadbee
   from the undocumented activity to cpu to fix up the
   warnings for the that.
