Subject: [PATCH] drm/vc4: hdmi: Create a custom connector state
|
|
|
|
When run with a higher bpc than 8, the clock of the HDMI controller needs
|
|
to be adjusted. Let's create a connector state that will be used at
|
|
atomic_check and atomic_enable to compute and store the clock rate
|
|
associated to the state.
