I think this will break bxt dsi state readout. It looks like it's still
broken :( I totally missed the review there I think, it should do this
rounding in compute_config, to guarantee that get_pipe_config matches.
I suggest you just put a FIXME onto this one and drop this hunk from your
patch.
With that addressed:
