dt-bindings: display: panel: document Synaptics TDDI panel
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.
