Subject: [PATCH 0/5] Introduce new mode validation callbacks

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.

  drm: Add crtc/encoder/bridge->mode_valid() callbacks
  drm: Use new mode_valid() helpers in connector probe helper
  drm: Introduce drm_bridge_mode_valid()
  drm: Use mode_valid() in atomic modeset
  drm: arc: Use crtc->mode_valid() callback
