      drm/i915: Pass down rc in intel_encoder->compute_config() · 204474a6
      由 Lyude Paul 提交于 
      Something that I completely missed when implementing the new MST VCPI
atomic helpers is that with those helpers, there's technically a chance
of us having to grab additional modeset locks in ->compute_config() and
furthermore, that means we have the potential to hit a normal modeset
deadlock. However, because ->compute_config() only returns a bool this
means we can't return -EDEADLK when we need to drop locks and try again
which means we end up just failing the atomic check permanently. Whoops.

So, fix this by modifying ->compute_config() to pass down an actual
error code instead of a bool so that the atomic check can be restarted
on modeset deadlocks.

Thanks to Ville Syrjälä for pointing this out!

Changes since v1:
* Add some newlines
* Return only -EINVAL from hsw_crt_compute_config()
* Propogate return code from intel_dp_compute_dsc_params()
* Change all of the intel_dp_compute_link_config*() variants
* Don't miss if (hdmi_port_clock_valid()) branch in
  intel_hdmi_compute_config()

[Cherry-picked from drm-misc-next to drm-intel-next-queued to fix
 linux-next & drm-tip conflict, while waiting for proper propagation of
 the DP MST series that this commit fixes. In hindsight, a topic branch
 might have been a better approach for it.]

      drm/i915/icl: implement the tc/legacy HPD {dis,}connect flows · 39d1e234
      由 Paulo Zanoni 提交于 
      Unlike the other ports, TC ports are not available to use as soon as
we get a hotplug. The TC PHYs can be shared between multiple
controllers: display, USB, etc. As a result, handshaking through FIA
is required around connect and disconnect to cleanly transfer
ownership with the controller and set the type-C power state.

This patch implements the flow sequences described by our
specification. We opt to grab ownership of the ports as soon as we get
the hotplugs in order to simplify the interactions and avoid surprises
in the user space side. We may consider changing this in the future,
once we improve our testing capabilities on this area.

v2:
 * This unifies the DP and HDMI patches so we can discuss everything
   at once so people looking at random single patches can actually
   understand the direction.
 * I found out the spec was updated a while ago. There's a small
   difference in the connect flow and the patch was updated for that.
 * Our spec also now gives a good explanation on what is really
   happening. As a result, comments were added.
 * Add some more comments as requested by Rodrigo (Rodrigo).
v3:
 * Downgrade a DRM_ERROR that shouldn't ever happen but we can't act
   on in case it does (Chris).

BSpec: 21750, 4250.
