Generic Display Pipeline are one of the compositor input sub-devices. GDP are dedicated to graphic input like RGB plans. GDP is part of Compositor hardware block which will be introduce later. A sti_layer structure is used to abstract GDP calls from Compositor. Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> Reviewed-by: Rob Clark <robdclark@gmail.com>
