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.
We proceed by introducing new helpers to call this new callbacks at 2/8, 3/8 and 4/8. Next, at 5/8 we modify the connector probe helper so that only modes which are supported by a given encoder+crtc combination are probbed. At 6/8 a helper function is introduced that calls all mode_valid() from a set of bridges. At 7/8 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 8/8 we use the new crtc->mode_valid() callback in arcpgu and remove the atomic_check() callback.
