Subject: [PATCH] drm/vc4: hdmi: Introduce an output_enabled flag
|
|
|
|
We currently poke at encoder->crtc in the ALSA code path to determine
|
|
whether the HDMI output is enabled or not, and thus whether we should
|
|
allow the audio output.
|
|
|
|
However, that pointer is deprecated and shouldn't really be used by
|
|
atomic drivers anymore. Since we have the infrastructure in place now,
|
|
let's just create a flag that we toggle to report whether the controller
|
|
is currently enabled and use that instead of encoder->crtc in ALSA.
