    Thanks!

    Note, there is no support for the devices with parallel interface in the DRM.
    So, basically we can't kill even a single one from fbtft if there is a user
    for it.

    Not sure.

    Yes and for the fact there are two drivers for the same chip in the DRM.
    Overall there are three different drivers for Ilitek 9341.
