DPU is short for the Display Processing Unit. It is the display controller on Qualcomm SDM845 chips. This change adds MDSS and DSI nodes to enable display on the target device.
Happy to see support reaching the level where we can introduce this in the dtsi! But, not all devices has a display and not all devices with display has DSI, so I would suggest that you mark these status = "disabled" and enable them in the board dts. Regards, Bjorn
