Subject[PATCH v1 6/6] drm/komeda: Add image enhancement support
Date
Besides scaling, Arm display scaler also can support image enhancement.
For support it, Add a new property "img_enhancement" to plane, then user
can turn on/off it by this property, and kernel follow user's requirement
to maitain the state and enable/disable the real HW image enhancement.
