    drm/tilcdc: add TI LCD Controller DRM driver (v4) · 16ea975e
    Rob Clark authored
    A simple DRM/KMS driver for the TI LCD Controller found in various
    smaller TI parts (AM33xx, OMAPL138, etc).  This driver uses the
    CMA helpers.  Currently only the TFP410 DVI encoder is supported
    (tested with beaglebone + DVI cape).  There are also various LCD
    displays, for which support can be added (as I get hw to test on),
    and an external i2c HDMI encoder found on some boards.
    
    The display controller supports a single CRTC.  And the encoder+
    connector are split out into sub-devices.  Depending on which LCD
    or external encoder is actually present, the appropriate output
    module(s) will be loaded.
    
    v1: original
    v2: fix fb refcnting and few other cleanups
    v3: get +/- vsync/hsync from timings rather than panel-info, add
        option DT max-bandwidth field so driver doesn't attempt to
        pick a display mode with too high memory bandwidth, and other
        small cleanups
    v4: remove some unneeded stuff from panel-info struct, properly
        set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs
