Thank you so much for sending this. The compression ratio was applied
to hdisplay
In hindsight, on the note of hdisplay, dsi_timing_setup() actually only
divides the visual portion - that is hdisplay out of htotal - without
affecting the back and front porch.
Since this clock inside the mode is based on the full htotal * vtotal *
..., should we compensate for that and only divide the visual portion of
the clock signal by 3? Otherwise we might not have enough clockticks to
perform the front and back porch (even though CMD mode doesn't really
have porches, I have yet to properly understand that part of the
signal).
Hi Marijn,
That's a fair point. Will change the pclk math accordingly.
Thanks,
Jessica Zhang

Don't forget to mention that this series depends on the DSC helpers. I
don't think the linked DSC 1.2 series depends on it (at least it doesn't
mention it):
