-Subject: [PATCH] drm/vc4: hdmi: Make sure the controller is powered up during
- bind
-
-In the bind hook, we actually need the device to have the HSM clock
-running during the final part of the display initialisation where we
-reset the controller and initialise the CEC component.
-
-Failing to do so will result in a complete, silent, hang of the CPU.
-
-Fixes: 411efa18e4b0 ("drm/vc4: hdmi: Move the HSM clock enable to runtime_pm")
-Signed-off-by: Maxime Ripard <maxime@cerno.tech>
