[PATCH 15/18] drm/vc4: hdmi: Rework the infoframe prototype

Maxime Ripard maxime at cerno.tech
Wed Mar 17 15:43:49 UTC 2021


In order to support a YUV output, we're going to need to have access to
the bridge state in the vc4_hdmi_set_avi_infoframe function. Since we
also need the connector state in that function, let's pass the full
atomic state.

While we're at it, since all those functions actually need the vc4_hdmi
structure, let's pass it instead of the drm_encoder.
