The DRM support code manages a pipeline of VSP entities, each backed by a media entity. When starting or stopping the pipeline, it starts and stops the media pipeline through the media API in order to store the pipeline pointer in every entity. The driver doesn't use the pipe pointer in media entities, neither does it rely on the other effects of the media_pipeline_start() and media_pipeline_stop() functions. Furthermore, as the media links for the DRM pipeline are never set up correctly, and as the pipeline can be modified dynamically when enabling or disabling planes, the current implementation is not correct. Remove the incorrect and unneeded code. While at it remove the outdated comment that states that entities are not started when the LIF is setup, as they now are. Signed-off-by:

Depending on the chosen standard, configure the decoder to use the appropriate color encoding standard (PAL-like, NTSC-like or SECAM). Until now, the decoder was not configured for a specific color standard, making it autodetect the color encoding. While this may sound fine, it potentially causes the wrong image tuning parameters to be applied (e.g. tuning parameters for NTSC are applied to a PAL source), and may confuse users about what the actual standard is in use. This commit explicitly configures the color standard the decoder will use, making it visually obvious if a wrong standard was chosen. Signed-off-by:

The user-supplied norm value gets overwritten by the generic .norm member from the norm_params. That way, we lose the specific norm the user may want to set. For instance, if the user specifies V4L2_STD_PAL_60, the value actually used will be V4L2_STD_525_60, which in the end will be as if the user had specified V4L2_STD_NTSC, since this is always the first bitfield we match the norm value against before configuring the hardware. The norm_params array is only there to match a norm with an output resolution. The norm value itself should not be changed. Signed-off-by:

Make use of the V4L2_STD_525_60 and V4L2_STD_625_50 defines to determine the vertical resolution to use when capturing. V4L2_STD_525_60 (resp. V4L2_STD_625_50) is the set of standards using 525 (resp. 625) lines per frame, independently of the color encoding. Signed-off-by:

Add support for the SECAM norm, using the "AVSECAM" decoder configuration sequence found in Windows driver's .INF file. For reference, the "AVSECAM" sequence in the .INF file is: 0x04,0x73,0xDC,0x72,0xA2,0x90,0x35,0x01,0x30,0x04,0x08,0x2D,0x28,0x08, 0x02,0x69,0x16,0x35,0x21,0x16,0x36 Signed-off-by:

Re-format the register {address, value} pairs so they follow the same order as the decoder configuration sequences in the Windows driver's .INF file. For instance, for PAL, the "AVPAL" sequence in the .INF file is: 0x04,0x68,0xD3,0x72,0xA2,0xB0,0x15,0x01,0x2C,0x10,0x20,0x2e,0x08,0x02, 0x02,0x59,0x16,0x35,0x17,0x16,0x36 Signed-off-by: -

Dmitry Osipenko authored
I've noticed that decoding fails sometime if size of bitstream buffer isn't aligned to 16K, probably because HW fetches data from memory in a 16K granularity and if the last chunk of data isn't aligned, HW reads garbage data beyond the dmabuf and tries to parse it. Signed-off-by:

Drivers that depend on ISAPNP currently can't be built with COMPILE_TEST. However, looking at isapnp.h, there are already stubs there to allow drivers to include it even when isa PNP is not supported. So, remove such dependencies when COMPILE_TEST. Acked-by:

All sound drivers that don't depend on PNP can be safelly build with COMPILE_TEST, as ISA provides function stubs to be used for such purposes. As a side effect, with this change, the radio-miropcm20 can now be built outside i386 with COMPILE_TEST. It should be noticed that ISAPNP currently depends on ISA. So, on drivers that depend on it, we need to add an explicit dependency on ISA, at least until another patch removes it. Acked-by:

Add the ability to process media device link change requests. Link enabling is a bit complicated on Gen3, whether or not it's possible to enable a link depends on what other links already are enabled. On Gen3 the 8 VINs are split into two subgroup's (VIN0-3 and VIN4-7) and from a routing perspective these two groups are independent of each other. Each subgroup's routing is controlled by the subgroup VIN master instance (VIN0 and VIN4). There are a limited number of possible route setups available for each subgroup and the configuration of each setup is dictated by the hardware. On H3 for example there are 6 possible route setups for each subgroup to choose from. This leads to the media device link notification code being rather large since it will find the best routing configuration to try and accommodate as many links as possible. When it's not possible to enable a new link due to hardware constrains the link_notifier callback will return -EMLINK. Signed-off-by:

The parsing and registering CSI-2 subdevices with the v4l2 async framework is a collaborative effort shared between the VIN instances which are part of the group. When the last VIN in the group is probed it asks all other VINs to parse its share of OF and record the async subdevices it finds in the notifier belonging to the last probed VIN. Once all CSI-2 subdevices in this notifier are bound proceed to register all VIN video devices of the group and crate media device links between all CSI-2 and VIN entities according to the SoC specific routing configuration.

In media controller mode all VIN instances needs to be part of the same media graph. There is also a need for each VIN instance to know about and in some cases be able to communicate with other VIN instances. Add an allocator framework where the first VIN instance to be probed creates a shared data structure and registers a media device. Consecutive VINs insert themself into the global group.

The V4L2 specification clearly documents the colorspace fields as being set by drivers for capture devices. Using the values supplied by userspace thus wouldn't comply with the API.

When the driver runs in media controller mode it should not directly control the subdevice instead userspace will be responsible for configuring the pipeline. To be able to run in this mode a different set of v4l2 operations needs to be used. Add a new set of v4l2 operations to support operation without directly interacting with the source subdevice.

On Gen3 a media controller API needs to be used to allow userspace to configure the subdevices in the pipeline instead of directly controlling a single source subdevice, which is and will continue to be the mode of operation on Gen2. Prepare for these two modes of operation by adding a flag to struct rvin_info which will control which mode to use. Signed-off-by:
