    Subject[PATCH 05/10] video: da8xx-fb: store current display information
    Date
    store current videomode and controller data so that reconfiguring can
    be done easily. Reconfiguring would be required in fb_set_par, which
    is going to be added soon.

    If these details are not stored, the work probe does to retrieve these
    information would have to repeated at the place of reconfiguring and
    modifying platform data would be necessary to handle controller data
    changes like bpp.
