* [media] v4l: v4l2_subdev userspace frame interval APILaurent Pinchart2011-03-221-0/+6
| | | | | | | | | | | | | | | The three new ioctl VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, VIDIOC_SUBDEV_G_FRAME_INTERVAL and VIDIOC_SUBDEV_S_FRAME_INTERVAL can be used to enumerate and configure a subdev's frame rate from userspace. Two new video::g/s_frame_interval subdev operations are introduced to support those ioctls. The existing video::g/s_parm operations are deprecated and shouldn't be used anymore.

* [media] v4l: v4l2_subdev userspace format APILaurent Pinchart2011-03-221-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

* [media] media: Links setupLaurent Pinchart2011-03-221-0/+2
| | | | | | | | | | | | | | | | | | | | Create the following ioctl and implement it at the media device level to setup links. - MEDIA_IOC_SETUP_LINK: Modify the properties of a given link The only property that can currently be modified is the ENABLED link flag to enable/disable a link. Links marked with the IMMUTABLE link flag can not be enabled or disabled. Enabling or disabling a link has effects on entities' use count. Those changes are automatically propagated through the graph.

* [media] media: Entities, pads and links enumerationLaurent Pinchart2011-03-221-0/+8
| | | | | | | | | | | | | | | | | | | | | Create the following two ioctls and implement them at the media device level to enumerate entities, pads and links. - MEDIA_IOC_ENUM_ENTITIES: Enumerate entities and their properties - MEDIA_IOC_ENUM_LINKS: Enumerate all pads and links for a given entity Entity IDs can be non-contiguous. Userspace applications should enumerate entities using the MEDIA_ENT_ID_FLAG_NEXT flag. When the flag is set in the entity ID, the MEDIA_IOC_ENUM_ENTITIES will return the next entity with an ID bigger than the requested one. Only forward links that originate at one of the entity's source pads are returned during the enumeration process.

* V4L/DVB (13163): Docbook/dvb: Rename isdbt.xml to dvbproperty.xmlMauro Carvalho Chehab2009-12-051-1/+1
| | | | | | | | | | | We'll need to add the documentation for FE_[GET|SET]_PROPERTY that is not specific to isdb-t. Instead of doing it at frontend.xml, it is better to have a separate session for it. Also, isdbt.xml assumes that those ioctls were already introduced, and documents several exisiting properties. So, better to just rename it and add the documentation for it, together with each existing property there. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
