-Subject: [PATCH] drm/vc4: hdmi: Store pixel frequency in the connector
- state
-
-The pixel rate is for now quite simple to compute, but with more features
-(30 and 36 bits output, YUV output, etc.) will depend on a bunch of
-connectors properties.
-
-Let's store the rate we have to run the pixel clock at in our custom
-connector state, and compute it in atomic_check.
