Document the Synaptics TDDI (Touch/Display Integration) panel hardware. Along with the MIPI-DSI panel, these devices also have an in-built LED backlight device and a touchscreen, all packed together in a single chip. Also, add compatibles for supported panels - TD4101 and TD4300. Both have the '-panel' suffix so as to remove any ambiguity between the panel and touchscreen chips.
