A lot of sensor drivers are labelled as "sensor-level" drivers. That's odd and somewhat confusing as the term isn't used elsewhere: these are just sensor drivers. Call them such. Signed-off-by:

The just parsed endpoint fwnode has to be put after use. Currently this is done only in error handling path. Fix that by putting node unconditionally after use. Fixes: 01b84448 ("media: v4l2: i2c: ov7670: Implement OF mbus configuration") Signed-off-by:

The external clock frequency was set to 23.88MHz by mistake because of a platform which cannot get closer to 24MHz. The supported by the driver external clock is 24MHz so set it correctly and also fix the values of the pixel clock and link clock. However allow 1% tolerance to the external clock as this difference is small enough to be insignificant. Signed-off-by:

For some types of tuners (Philips FMD1216ME(X) MK3 currently) we know that letting TDA9887 output port 1 remain high (inactive) will switch FM radio to mono mode. Let's make use of this functionality - nothing changes for the default stereo radio mode. Tested on a Medion 95700 board which has a FMD1216ME tuner. Signed-off-by:

Add a new control V4L2_CID_MPEG_VIDEO_VP9_PROFILE for VP9 profiles. This control allows selecting the desired profile for VP9 encoder and querying for supported profiles by VP9 encoder/decoder. Though this control is similar to V4L2_CID_MPEG_VIDEO_VP8_PROFILE, we need to separate this control from it because supported profiles usually differ between VP8 and VP9. Signed-off-by:

Keiichi Watanabe authored
Add a menu control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile and make V4L2_CID_MPEG_VIDEO_VPX_PROFILE an alias of it. This new control is used to select the desired profile for VP8 encoder and query for supported profiles by VP8 encoder/decoder. Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name contains 'VPX', it works only for VP8 because supported profiles usually differ between VP8 and VP9. In addition, this control cannot be used for querying since it is not a menu control but an integer control, which cannot return an arbitrary set of supported profiles. The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with controls for other codec profiles. (e.g. H264) In addition, this patch also fixes the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in drivers of Qualcomm's venus and Samsung's s5p-mfc. Signed-off-by:

The IPU can only capture RGB565 with two 8-bit cycles in bayer/generic mode on the parallel bus, compared to a specific mode on MIPI CSI-2. To handle this, we extend imx_media_pixfmt with a cycles per pixel field, which is used for generic formats on the parallel bus. Based on the selected format and bus, we then update the width to account for the multiple cycles per pixel. Signed-off-by:

Jan Luebbe authored
By checking and handling the internal IPU formats (ARGB or AYUV) first, we don't need to check whether it's a bayer format, as we can default to passing the input format on in all other cases. This simplifies handling the different configurations for RGB565 between parallel and MIPI CSI-2, as we don't need to check the details of the format anymore. Signed-off-by:

When running with media-controller link the parallel input media entities with the VIN entities at 'complete' callback time. To create media links the v4l2_device should be registered first. Check if the device is already registered, to avoid double registrations. Signed-off-by:

The rcar-vin driver so far had a mutually exclusive code path for handling parallel and CSI-2 video input subdevices, with only the CSI-2 use case supporting media-controller. As we add support for parallel inputs to Gen3 media-controller compliant code path now parse both port@0 and port@1, handling the media-controller use case in the parallel bound/unbind notifier operations.

Jacopo Mondi authored
Media bus configuration flags and media bus type were so far a property of each VIN instance, as the subdevice they were connected to was immutable during the whole system life time. With the forth-coming introduction of parallel input devices support, a VIN instance can have the subdevice it is connected to switched at runtime, from a CSI-2 subdevice to a parallel one and viceversa, through the modification of links between media entities in the media controller graph. To avoid discarding the per-subdevice configuration flags retrieved by v4l2_fwnode parsing facilities, cache them in the 'rvin_graph_entity' member of each VIN instance, opportunely renamed to 'rvin_parallel_entity'. Also modify the register configuration function to take mbus flags into account when running on a bus type that supports them. The media bus type currently in use will be updated in a follow-up patch to the link state change notification function. Signed-off-by:

During the notifier initialization, memory for the list of associated async subdevices is reserved during the fwnode endpoint parsing from the v4l2-async framework. If the notifier registration fails, that memory should be released and the notifier 'cleaned up'. Catch the notifier registration error and perform the cleanup both for the group and the parallel notifiers. Signed-off-by:

As CSI-2 subdevices are shared between several VIN instances, a shared notifier to collect the CSI-2 async subdevices is required. So far, the rcar-vin driver used the notifier of the last VIN instance to probe but with the forth-coming introduction of parallel input subdevices support in mc-compliant code path, each VIN may register its own notifier if any parallel subdevice is connected there. To avoid registering a notifier twice (once for parallel subdev and one for the CSI-2 subdevs) create a group notifier, shared by all the VIN instances. Signed-off-by:

A memory-to-memory pipeline device consists in three entities: two DMA engine and one video processing entities. The DMA engine entities are linked to a V4L interface. This commit add a new v4l2_m2m_{un}register_media_controller API to register this topology. For instance, a typical mem2mem device topology would look like this: Device topology - entity 1: source (1 pad, 1 link) type Node subtype V4L flags 0 pad0: Source -> "proc":1 [ENABLED,IMMUTABLE] - entity 3: proc (2 pads, 2 links) type Node subtype Unknown flags 0 pad0: Source -> "sink":0 [ENABLED,IMMUTABLE] pad1: Sink <- "source":0 [ENABLED,IMMUTABLE] - entity 6: sink (1 pad, 1 link) type Node subtype V4L flags 0 pad0: Sink <- "proc":0 [ENABLED,IMMUTABLE] [hans.verkuil@cisco.com: mark interface links as IMMUTABLE] Suggested-by: -
Hans Verkuil authored
Currently links between entities and an interface are just marked as ENABLED. But (at least today) these links cannot be disabled by userspace or the driver, so they should also be marked as IMMUTABLE. It might become possible that drivers can disable such links (if for some reason the device node cannot be used), so we might need to add a new link flag at some point to mark interface links that can be changed by the driver but not by userspace.
