Those documentation are part of the kAPI one. Move to the right place. Signed-off-by: Mauro Carvalho Chehab

[media] samples: v4l: from Documentation to samples directory

2016-05-09T21:34:37+00:00

With the new autoksyms support, we can run into a situation where the v4l pci skeleton module is the only one using some exported symbols that get dropped because they are never referenced by the kernel otherwise, causing a build problem: ERROR: "vb2_dma_contig_memops" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined! ERROR: "vb2_dma_contig_init_ctx_attrs" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined! ERROR: "v4l2_match_dv_timings" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined! ERROR: "v4l2_find_dv_timings_cap" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined! ERROR: "v4l2_valid_dv_timings" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined! ERROR: "v4l2_enum_dv_timings_cap" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined! ERROR: "vb2_dma_contig_cleanup_ctx" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined! Specifically, we do look in the samples directory for users of symbols, but not the Documentation directory. This solves the build problem by moving the connector sample into the same directory as the other samples.

[media] media framework: rename pads init function to media_entity_pads_init()

2016-01-11T14:19:03+00:00

With the MC next gen rework, what's left for media_entity_init() is to just initialize the PADs. However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it. Signed-off-by: Mauro Carvalho Chehab

[media] media-entity.h: rename entity.type to entity.function

2016-01-11T14:19:00+00:00

Entities should have one or more functions. Calling it as a type proofed to not be correct, as an entity could eventually have more than one type. So, rename the field as function. Please notice that this patch doesn't extend support for multiple function entities. Such change will happen when we have real case drivers using it. No functional changes.

[media] media: get rid of unused "extra_links" param on media_entity_init()

2016-01-11T14:18:39+00:00

Currently, media_entity_init() creates an array with the links, allocated at init time. It provides a parameter (extra_links) that would allocate more links than the current needs, but this is not used by any driver. As we want to be able to do dynamic link allocation/removal, we'll need to change the implementation of the links. So, before doing that, let's first remove that extra unused parameter, in order to cleanup the interface first.

[media] v4l2-subdev: allow subdev to send an event to the v4l2_device notify function

2015-05-20T16:40:02+00:00

All drivers use custom notifications, in particular when source changes. The bridge only has to map the subdev that sends it to whatever video node it is connected to. Signed-off-by: Jean-Michel Hautbois Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-pci-skeleton: add a V4L2 PCI skeleton driver
