Finally got around testing these. Looks like applying this patch
breaks things for devices not using the new clocks entry?
For example, SPI now breaks causing "imprecise external abort" during boot
at least on droid 4.

Above should be cm_l4per: cm_l4per@1400, right?

You should update the binding doc accordingly if the "cm_l4per@0" node
there is not needed. I also noticed the binding doc still has
"#clock-cells = <4>" while it should be 2.
