This lets omap_vout driver build and run without VRFB. It works along the lines of the following patch series: OMAP: DSS2: OMAPFB: Allow FB_OMAP2 to build without VRFB https://patchwork.kernel.org/patch/105371/ Since VRFB is tightly coupled with the omap_vout driver, a handful of vrfb specific functions have been defined and placed in omap_vout_vrfb.c A new enum called vout_rotation_type is introduced to differentiate between no rotation and vrfb rotation. A member rotation_type is introduced in omapvideo_info, this allows to call vrfb specific functions only if the rotation type is VOUT_ROT_VRFB When the rotation_type is set to VOUT_ROT_NONE, the S_CTRL ioctl prevents the user setting a non zero rotation or non zero mirror value.
