[1/1] arm64: dts: qcom: enable dual ("bonded") DSI mode for DB845c commit: 8721e18ca6960f3c5a6a7f58245d9ab084ad09dd Best regards,

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.
