[PATCH v4 00/10] 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. This
patch is available at [2] and the series depends on it.

We proceed by introducing new helpers to call this new callbacks
at 1/10.

At 2/10 a helper function is introduced that calls all mode_valid()
from a set of bridges.

Next, at 3/10 we modify the connector probe helper so that only modes
which are supported by a given bridge+encoder+crtc combination are
probbed.

At 4/10 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, from 5/10 to 10/10 we use the new callbacks in drivers that
can implement it.

Jose Abreu (10):
  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
  drm/bridge: analogix-anx78xx: Use bridge->mode_valid() callback
  drm/bridge/synopsys: dw-hdmi: Use bridge->mode_valid() callback
  drm/arm: malidp: Use crtc->mode_valid() callback
  drm/atmel-hlcdc: Use crtc->mode_valid() callback
  drm: vc4: Use crtc->mode_valid() and encoder->mode_valid() callbacks
