New requirement? I've submitted not a single patch to the DT-bindings
sources and didn't get any comment from Rob about that. In addition
There are DT bindings with names different from what is defined in the
compatible name. Moreover there are tons of bindings with various
compatible names. What name to choose then? Finally the current name
is too generic to use for actual DW uMCTL2 DDRC controller.
