This patch update documentation of device tree bindings for the rockchip DSI controller based on the Synopsys DesignWare MIPI DSI host controller.
It might help to describe why you're doing this. Just saying "update" is pretty vague. In this case, it's something like "describe panel/port links, including unit addresses".

^^ You're removing #{address,size}-cells here, but then port@0 will still have subnodes that have 'reg' properties, so I think you need to keep the -cells properties.
