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. Archit Taneja (3): V4L/DVB: OMAP_VOUT: Move some functions and preprocessor defines from omap_vout V4L/DVB: OMAP_VOUT: Create a seperate vrfb functions library V4L/DVB: OMAP_VOUT: Use rotation_type to choose between vrfb rotation and no rotation drivers/media/video/omap/Kconfig | 2 +- drivers/media/video/omap/Makefile | 1 + drivers/media/video/omap/omap_vout.c | 560 +++++------------------------ drivers/media/video/omap/omap_vout_vrfb.c | 411 +++++++++++++++++++++ drivers/media/video/omap/omap_vout_vrfb.h | 42 +++ drivers/media/video/omap/omap_voutdef.h | 77 ++++ drivers/media/video/omap/omap_voutlib.c | 44 +++ drivers/media/video/omap/omap_voutlib.h | 2 + 8 files changed, 659 insertions(+), 480 deletions(-) create mode 100644 drivers/media/video/omap/omap_vout_vrfb.c create mode 100644 drivers/media/video/omap/omap_vout_vrfb.h -- Version 3: - Introduce a new enum at V4L2 driver level which cleanly differentiates between vrfb rotation and no rotation, incorporate comments given for v2 Version 2: - Don't try to enable SDRAM rotation , return an error if non zero rotation is attempted when rotation_type is set to SDMA rotation.
