2011-09-21[media] OMAP_VOUT: Fix build break caused by update_mode removal in DSS2archit taneja
The DSS2 driver does not support the configuration of the update_mode of a panel anymore. Remove the setting of update_mode done in omap_vout_probe(). Ignore configuration of TE since omap_vout driver doesn't support manual update displays anyway.

2011-07-27[media] V4L2: OMAP: VOUT: dma map and unmap v4l2 buffers in qbuf and dqbufAmber Jain
Add support to map the buffer using dma_map_single during qbuf which inturn calls cache flush and unmap the same during dqbuf. This is done to prevent the artifacts seen because of cache-coherency issues on OMAP4 Signed-off-by: Amber Jain <amber@ti.com> Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-07-27[media] OMAP_VOUT: Create separate file for VRFB related API'sarchit taneja
Introduce omap_vout_vrfb.c and omap_vout_vrfb.h, for all VRFB related API's, making OMAP_VOUT driver independent from VRFB. This is required for OMAP4 DSS, since OMAP4 doesn't have VRFB block. Added new enum vout_rotation_type and "rotation_type" member to omapvideo_info, this is initialized based on the arch type in omap_vout_probe. The rotation_type var is now used to choose between vrfb and non-vrfb calls.

Move the independent functions omap_vout_alloc_buffer() and omap_vout_free_buffer() to omap_voutlib.c.

2011-07-27[media] V4L2: omap_vout: Remove GFP_DMA allocation as ZONE_DMA is not ↵Amber Jain
configured on OMAP Remove GFP_DMA from the __get_free_pages() call from omap_vout as ZONE_DMA is not configured on OMAP. Earlier the page allocator used to return a page from ZONE_NORMAL even when GFP_DMA is passed and CONFIG_ZONE_DMA is disabled. As a result of commit a197b59ae6e8bee56fcef37ea2482dc08414e2ac, page allocator returns null in such a scenario with a warning emitted to kernel log.

2011-07-27[media] drivers/media: static should be at beginning of declarationJesper Juhl
Make sure that the 'static' keywork is at the beginning of declaration for drivers/media/video/omap/omap_vout.c This gets rid of warnings like when building with -Wold-style-declaration (and/or -Wextra which also enables it).

2011-07-01[media] omap_vout: Added check in reqbuf & mmap for buf_size allocationVaibhav Hiremath
The usecase where, user allocates small size of buffer through bootargs (video1_bufsize/video2_bufsize) and later from application tries to set the format which requires larger buffer size, driver doesn't check for insufficient buffer size and allows application to map extra buffer. This leads to kernel crash, when user application tries to access memory beyond the allocation size. Added check in both mmap and reqbuf call back function, and return error if the size of the buffer allocated by user through bootargs is less than the S_FMT size.

2011-07-01[media] OMAP_VOUT: Change hardcoded device node number to -1Vaibhav Hiremath
With addition of media-controller framework, now we have various device nodes (/dev/videoX) getting created, so hardcoding minor number in video_register_device() is not recommended. So let V4L2 framework choose free minor number for the device. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-01[media] OMAP_VOUTLIB: Fix wrong resizer calculationVladimir Pantelic
