   4 Subject: [PATCH] drm/panel-simple: Allow the bus format to be read
   5  from DT for panel-dpi
   6
   7 The "panel-dpi" compatible string configures panel from device tree,
   8 but it doesn't provide any way of configuring the bus format (colour
   9 representation), nor does it populate it.
  10
  11 Add a DT parameter "bus-format" that allows the MEDIA_BUS_FMT_xxx value
  12 to be specified from device tree.
