In MDP5 Layer Mixer HW, the blender output is only the blended color components (i.e R, G and B, or COLOR0/1/2 in MDP5 HW terminology). This is fed to the BG input of the next blender. We also need to provide an alpha (COLOR3) value for the BG input at the next stage. This is configured via using the REG_MDP5_LM_BLEND_COLOR_OUT register. For each stage, we can propagate either the BG or FG alpha to the next stage. The approach taken by the driver is to propagate FG alpha, if the plane staged on that blender has an alpha. If it doesn't, we try to propagate the base layer's alpha. This is borrowed from downstream MDP5 kernel driver. Without this, we don't see any cursor plane content.
