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. Next, at 2/5 we modify the connector probe helper so that only modes which are supported by a given encoder+crtc combination are probbed. At 3/5 a helper function is introduced that calls all mode_valid() from a set of bridges. At 4/5 we call all the mode_valid() callbacks for a given pipeline so that the mode is validated. This is done before calling mode_fixup(). Finally, at 5/5 we use the new crtc->mode_valid() callback in arcpgu and remove the atomic_check() callback.
