      drm/tilcdc: add TI LCD Controller DRM driver (v4) · 16ea975e
      Rob Clark 提交于
      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
