    Subject[PATCH 5.2 190/215] drm/panel: Add support for Armadeus ST0700 Adapt
    Date
    From: Sébastien Szymanski <sebastien.szymanski@armadeus.com>

    commit c479450f61c7f1f248c9a54aedacd2a6ca521ff8 upstream.

    This patch adds support for the Armadeus ST0700 Adapt. It comes with a
    Santek ST0700I5Y-RBSLW 7.0" WVGA (800x480) TFT and an adapter board so
    that it can be connected on the TFT header of Armadeus Dev boards.
