Subject: [PATCH] drm/vc4: hdmi: Don't poll for the infoframes status
|
|
on setup
|
|
|
|
The infoframes are sent at a regular interval as a data island packet,
|
|
so we don't need to wait for them to be sent when we're setting them up.
|
|
|
|
However, we do need to poll when we're enabling since the we can't
|
|
update the packet RAM until it has been sent.
|
|
|
|
Let's add a boolean flag to tell whether we want to poll or not to
|
|
support both cases.
