2016-04-25[media] DocBook media: drop 'experimental' annotationsHans Verkuil21-185/+1
Drop the 'experimental' annotations. The only remaining part of the API that is still marked 'experimental' are the debug ioctls/structs, and that is intentional. Only the v4l2-dbg application should use those. All others have been around for years, so it is time to drop the 'experimental' designation.

2016-04-25[media] videodev2.h: remove 'experimental' annotationsHans Verkuil1-28/+10
Most of what is marked as 'experimental' has been around for years. Time to drop that annotation. The only remaining 'experimental' bits of the API are the debug ioctls and structs: these should remain experimental since the only application that should use this is v4l2-dbg.

2016-04-25[media] tw686x-video: test for 60Hz instead of 50HzHans Verkuil1-4/+4
When determining if the standard is 50 or 60 Hz it is standard practice to test for 60 Hz instead of 50 Hz. This doesn't matter normally, except if the user specifies both 60 and 50 Hz standards.

2016-04-20[media] v4l2-device.h: add v4l2_device_mask_ variantsHans Verkuil2-2/+55
The v4l2_device_call_* defines filter subdevs based on the grp_id value. But some drivers use a bitmask, so instead of filtering by grp_id == value, you want to filter by grp_id & value. Make variants of these defines to do this. The 'has_op' define has been extended to have a grp_id argument as well, and a mask variant has been added. This extra argument required a change to go7007.

2016-04-20[media] media: Support Intersil/Techwell TW686x-based video capture cardsEzequiel Garcia10-0/+2039
This commit introduces the support for the Techwell TW686x video capture IC. This hardware supports a few DMA modes, including scatter-gather and frame (contiguous). This commit makes little use of the DMA engine and instead has a memcpy based implementation. DMA frame and scatter-gather modes support may be added in the future. Currently supported chips: - TW6864 (4 video channels), - TW6865 (4 video channels, not tested, second generation chip), - TW6868 (8 video channels but only 4 first channels using built-in video decoder are supported, not tested), - TW6869 (8 video channels, second generation chip).

2016-04-20[media] media-device: get rid of the spinlockMauro Carvalho Chehab3-39/+22
Right now, the lock schema for media_device struct is messy, since sometimes, it is protected via a spin lock, while, for media graph traversal, it is protected by a mutex. Solve this conflict by always using a mutex. As a side effect, this prevents a bug when the media notifiers is called at atomic context, while running the notifier callback: BUG: sleeping function called from invalid context at mm/slub.c:1289 in_atomic(): 1, irqs_disabled(): 0, pid: 3479, name: modprobe 4 locks held by modprobe/3479: #0: (&dev->mutex){......}, at: [<ffffffff81ce8933>] __driver_attach+0xa3/0x160 #1: (&dev->mutex){......}, at: [<ffffffff81ce8941>] __driver_attach+0xb1/0x160 #2: (register_mutex#5){+.+.+.}, at: [<ffffffffa10596c7>] usb_audio_probe+0x257/0x1c90 [snd_usb_audio] #3: (&(&mdev->lock)->rlock){+.+.+.}, at: [<ffffffffa0e6051b>] media_device_register_entity+0x1cb/0x700 [media] CPU: 2 PID: 3479 Comm: modprobe Not tainted 4.5.0-rc3+ #49 Hardware name: /NUC5i7RYB, BIOS RYBDWi35.86A.0350.2015.0812.1722 08/12/2015 0000000000000000 ffff8803b3f6f288 ffffffff81933901 ffff8803c4bae000 ffff8803c4bae5c8 ffff8803b3f6f2b0 ffffffff811c6af5 ffff8803c4bae000 ffffffff8285d7f6 0000000000000509 ffff8803b3f6f2f0 ffffffff811c6ce5 Call Trace: [<ffffffff81933901>] dump_stack+0x85/0xc4 [<ffffffff811c6af5>] ___might_sleep+0x245/0x3a0 [<ffffffff811c6ce5>] __might_sleep+0x95/0x1a0 [<ffffffff8155aade>] kmem_cache_alloc_trace+0x20e/0x300 [<ffffffffa0e66e3d>] ? media_add_link+0x4d/0x140 [media] [<ffffffffa0e66e3d>] media_add_link+0x4d/0x140 [media] [<ffffffffa0e69931>] media_create_pad_link+0xa1/0x600 [media] [<ffffffffa0fe11b3>] au0828_media_graph_notify+0x173/0x360 [au0828] [<ffffffffa0e68a6a>] ? media_gobj_create+0x1ba/0x480 [media] [<ffffffffa0e606fb>] media_device_register_entity+0x3ab/0x700 [media] Reviewed-by: Javier Martinez Canillas <[email protected]> Acked-by: Sakari Ailus <[email protected]> Acked-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2016-04-13[media] v4l: vsp1: Add support for the RPF alpha multiplier on Gen3Laurent Pinchart4-3/+73
The Gen3 RPF includes an alpha multiplier that can both multiply the alpha channel by a fixed global alpha value, and multiply the pixel components to convert the input to premultiplied alpha. As alpha premultiplication is available in the BRU for both Gen2 and Gen3 we handle it there and use the Gen3 alpha multiplier for global alpha multiplication only. This prevents conversion to premultiplied alpha if no BRU is present in the pipeline, that use case will be implemented later if needed.
