This series is a follow up from the discussion at [1]. We start by introducing crtc->mode_valid(), encoder->mode_valid() and bridge->mode_valid() callbacks which will be used in followup patches and also by cleaning the documentation a little bit. This patch is available at [2] and the series depends on it.
We proceed by introducing new helpers to call this new callbacks at 1/10.
At 2/10 a helper function is introduced that calls all mode_valid() from a set of bridges.
Next, at 3/10 we modify the connector probe helper so that only modes which are supported by a given bridge+encoder+crtc combination are probbed.
At 4/10 we call all the mode_valid() callbacks for a given pipeline, except the connector->mode_valid one, so that the mode is validated. This is done before calling mode_fixup().
Finally, from 5/10 to 10/10 we use the new callbacks in drivers that can implement it.
