      drm/tilcdc: add support for LCD panels (v5) · 0d4bbaf9
      Rob Clark 提交于
      Add an output panel driver for LCD panels.  Tested with LCD3 cape on
      beaglebone.
      
      v1: original
      v2: s/of_find_node_by_name()/of_get_child_by_name()/ from Pantelis
          Antoniou
      v3: add backlight support
      v4: rebase to latest of video timing helpers
      v5: remove some unneeded fields from panel-info struct, add DT bindings

      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

      ARM: OMAP2PLUS: DSS: Ensure DSS works correctly if display is enabled in bootloader · b923d40d
      Archit Taneja 提交于
      Resetting DISPC when a DISPC output is enabled causes the DSS to go into an
      inconsistent state. Thus if the bootloader has enabled a display, the hwmod code
      cannot reset the DISPC module just like that, but the outputs need to be
      disabled first.
      
      Add function dispc_disable_outputs() which disables all active overlay manager
      and ensure all frame transfers are completed.
      
      Modify omap_dss_reset() to call this function and clear DSS_CONTROL,
      DSS_SDI_CONTROL and DSS_PLL_CONTROL so that DSS is in a clean state when the
      DSS2 driver starts.
      
      This resolves the hang issue(caused by a L3 error during boot) seen on the
      beagle board C3, which has a factory bootloader that enables display. The issue
      is resolved with this patch.
      
      Thanks to Tomi and Sricharan for some additional testing.
