-Subject: [PATCH 27/69] DSS2: VRFB rotation and mirroring implemented.
-
-DSS2 modified to accept the rotation_type input
-to get the dma or VRFB rotation.
-
-DSS2: VRFB: Changed to pass DSS mode to vrfb_setup instead of Bpp.
-
-VRFB size registers requires the width to be halved when the
-mode is YUV or UYVY. So modifed to pass the mode to omap_vrfb_setup
-function.
-
-Code added by Tim Yamin for few bug fixes
