From: Xinlei Lee <xinlei.lee@mediatek.com> Add dt-binding documentation of DSI for MediaTek MT8188 SoC. Because of the difference between SOC and DSI cmd packet control, for MT8188, it is necessary to increase the DSI_CMDQ_SIZE control when sending long packets to initialize the panel. Of course, this will not affect the sending of short packets. Base on the branch of linus/master v6.3.
