[PATCH 3/6] davinci: vpbe: add fbdev driver

Prabhakar Lad prabhakar.csengg at gmail.com
Wed Apr 24 08:00:05 EDT 2013


From: Lad, Prabhakar <prabhakar.csengg at gmail.com>

add the fbdev driver for DMX which uses an OSD layer
with RGB565/RGB888 support and an attribute window which can
also be doubled as another RGB565 window. The fbdev supports
fb0 and fb2 for  OSD0 and OSD1, and also supports video windows
with fb1 and fb3.
