dual display edp + dsi supported on TK1 ?

we have already made it worked on our board (refer to TK1) with edp/lvds + hdmi,and now I am trying edp + dsi,note that the section “24.5 SOR Security” on the TRM data sheet seems that,displayB can only connect HDMI while display A can connect DSIA/DSIB/eDP/LVDS. the other section “21.1 Features” says that “Additional serial output resource(SOR) to support LVDS,eDP concurrent with HDMI or MIPI-DSI”. I am confused now.
