Currently DP driver will allocate panel bridge for eDP panels. This supports only the following topology: - eDP encoder ⇒ eDP panel (wrapped using panel-bridge) Simplify this code to just check if there is any next bridge in the chain (be it a panel bridge or regular bridge). Rename panel_bridge field to next_bridge accordingly. This allows one to use e.g. one of the following display topologies: - eDP encoder ⇒ ptn3460 ⇒ fixed LVDS panel - eDP encoder ⇒ ptn3460 ⇒ LVDS connector with EDID lines for panel autodetect - eDP encoder ⇒ ptn3460 ⇒ THC63LVD1024 ⇒ DPI panel. - eDP encoder ⇒ LT8912 ⇒ DSI panel Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Tested-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Reviewed-by: Stephen Boyd <swboyd@chromium.org> Link: https://lore.kernel.org/r/20220211224006.1797846-3-dmitry.baryshkov@linaro.org Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
