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.
