Not within this patch, it is not relevant to bonded DSI mode.

[PATCH] arm64: dts: qcom: enable dual ("bonded") DSI mode for DB845c
Now as both lt9611 and drm/msm drivers were updated to handle the 4k
modes over DSI, enable "bonded" DSI mode on DB845c. This way the board
utilizes both DSI links and thus can support 4k on the HDMI output.
