Subject: [PATCH] drm/vc4: hdmi: Make sure the device is powered with
|
|
CEC
|
|
|
|
Similarly to what we encountered with the detect hook with DRM, nothing
|
|
actually prevents any of the CEC callback from being run while the HDMI
|
|
output is disabled.
|
|
|
|
However, this is an issue since any register access to the controller
|
|
when it's powered down will result in a silent hang.
|
|
|
|
Let's make sure we run the runtime_pm hooks when the CEC adapter is
|
|
opened and closed by the userspace to avoid that issue.
|
|
|
