[PATCH v3 0/6] Introduce new mode validation callbacks

Show all headers | View raw

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.

Jose Abreu (6):
  drm: Add crtc/encoder/bridge->mode_valid() callbacks
  drm: Add drm_{crtc/encoder/connector}_mode_valid()
  drm: Introduce drm_bridge_mode_valid()
  drm: Use new mode_valid() helpers in connector probe helper
  drm: Use mode_valid() in atomic modeset
  drm: arc: Use crtc->mode_valid() callback
