[Intel-gfx] [Patch 1/4] drm/I915: Add the enhancement property for SDVO-TV
yakui.zhao at intel.com
yakui.zhao at intel.com
Thu Sep 10 09:45:46 CEST 2009
From: Zhao Yakui <yakui.zhao at intel.com>
When the sdvo device is detected as SDVO-TV, we will check whether the
sepecific picture enhancement is supported. If it is supported, we will
add the corresponnding property for SDVO-TV. We will add the following
property for the SDVO-TV enhancements if they are supported:
Contrast/Brightness/Saturation/Hue:
left/right/top/bottom margin: This is implemented by using the horizontal/
vertical overscan enhancements. When the overscan enhancements are supported,
the above properties will be added. This is to be compatible with what we have
done in integrated-TV.
horizontal pos/vertical pos:
