[v10,3/5] arm64: dts: ti: k3-j784s4-main: Add DSS and DP-bridge node
Commit Message
From: Rahul T R <r-ravikumar@ti.com>
Add DSS and DP-bridge node for J784S4 SoC. DSS IP in J784S4 is
same as DSS IP in J721E, so same compatible is being used.
The DP is Cadence MHDP8546.

Okay.

I will mention that the remote-endpoint are on the board so all the
properties are defined there together. So keeping it empty here.
Other way could be to add #address-cells and #size-cell here with port
child-node. And its remote end point added in the board file. But node
would still be incomplete here.
