Subject: [PATCH v2 4/5] dt-bindings: display/msm: dsi-controller-main:
 Document dual panel property

The DSI interface can be connected to a panel that has a dual DSI channel,
or to two separate panels, each equipped with a single DSI channel. To
prevent the DSC configuration for the dual panel setup from disrupting the
current configuration of a single panel with a dual DSI channel, add a dual
panel property to support the use of two panels.
