Is there a different "tcsr"? Does the "_regs" suffix add any value?

Rob has pointed out a few times that a lone "syscon" isn't going to be accepted going forward. Could you also add a qualifying "qcom,sc7280-tcsr" or something like that?

As above "qcom,sc7280-imem"? I presume we need some new binding documents for these two though, perhaps you can add the specific compatibles and we agree that one of us will write these two bindings soon? Regards, Bjorn
