OK, will use DSI link for all later description. > > Also I don't follow how DSC configuration for a dual panel setup can > disrupt current (?) configuration of a single panel. For the disruption, Marijn mentioned it in the last post. https://gitlab.freedesktop.org/drm/msm/-/issues/41#note_2411541 > > > > > Signed-off-by: Jun Nie <jun....@linaro.org> > > --- > > .../devicetree/bindings/display/msm/dsi-controller-main.yaml | 8 > > +++++++- > > 1 file changed, 7 insertions(+), 1 deletion(-) > > > > diff --git > > a/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml > > b/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml > > index > > ffbd1dc9470e2091b477b0c88392d81802119f48..e3f2eabde27609a66d6d81fafcb14e1bc014613c > > 100644 > > --- a/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml > > +++ b/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml > > @@ -88,9 +88,15 @@ properties: > > qcom,dual-dsi-mode: > > type: boolean > > description: | > > - Indicates if the DSI controller is driving a panel which needs > > + Indicates if the DSI controller is driving display device which needs > > Unrelated change > > > 2 DSI links. > > > > + qcom,dual-panel: > > + type: boolean > > + description: | > > + Indicates if the DSI controller is driving display device that > > composed > > + with 2 independent panels and needs 2 DSI links. > > How is tht different from qcom,dual-dsi-mode? Your questioning is right. The dual panel case is a subset of dual-dsi-mode, not parallel with dual-dsi-mode. It is single panel with 2 DSI link by default, and 2 panel with 1 DSI link in each panel if property dual-panel is present. > > > + > > qcom,master-dsi: > > type: boolean > > description: | > > > > -- > > 2.34.1 > > > > -- > With best wishes > Dmitry
