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. We proceed by introducing new helpers to call this new callbacks at 2/6. At 3/6 a helper function is introduced that calls all mode_valid() from a set of bridges. Next, at 4/6 we modify the connector probe helper so that only modes which are supported by a given bridge+encoder+crtc combination are probbed. At 5/6 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, at 6/6 we use the new crtc->mode_valid() callback in arcpgu and remove the atomic_check() callback.
