(1) I think people like to align multi-line dts field values, so there
should be one more ' ' before each <&topckgen ...>.

(2) it is a bit awkward that these names do not match their clock
names.  This seems more straightforward:

  clock-names = "vdec", "mfg", "venc", "mm", "venc_lt";

(3) the scpsys binding patch does not list the clock fields.

(4) I don't think a patch with these CLK_TOP_* has been sent to the
list for review yet.

Thanks,
