-Subject: drm/i915: Configure the TV sense state correctly on GM45 to make TV detection reliable
-
-From: Zhao Yakui <yakui.zhao@intel.com>
-
-commit fb8b5a39b6310379d7b54c0c7113703a8eaf4a57 upstream.
-
-The TV detection logic is not reliable on the Cantiga platform.
-Sometimes the TV will be misdetected as the following two cases:
-- TV is misdetected on some laptops. e.g. There is no TV connector
-port or no TV is attached. But the TV is shown as connected.
-- TV connector type is misdetected. e.g. the component TV is
-attached, but the TV is shown as S-video type.
-
-According to the hardware requirement, the TV sense state bits of TV DAC
-register should be cleared to zero on Cantiga platfrom.
