-Subject: [PATCH] drm/vc4:hdmi: Delay cec_phys_addr_invalidate
-
-Wait briefly before generating the cec_phys_addr_invalidate,
-and skip it if it's immediately followed by a valid one.
-
-This avoids the confusion of TV generating a powered up event
-and libcec generating an active source message which swicthes
-everything back on after a power off.
-
-See:
-https://forum.libreelec.tv/thread/24783-tv-avr-turns-back-on-right-after-turning-them-off
