Novatek NT51021 is a display driver IC that can drive DSI panel. It is also present in the BOE TV101WUM-NX0 video mode panel, which is a WUXGA panel with a resolution of 1200x1920 and 10.1 inches size. It is found in Xiaomi Mi Pad 4 Plus. Also it's present in the BOE-TV080WUM-NX2 video mode panel, which also has a resolution of 1200x1920, but 8 inches size. It is found in Xiaomi Mi Pad 4. And also it's present in the BOE-TV101WUM-NM0. It's found in Amazon Fire HD 10 (2017). Add the bindings for display driver for the IC, with support added for this BOE TV101WUM-NX0 and TV080WUM-NX2 WUXGA video mode panels.
