The CAL driver is video node centric, it controls the whole device through the video device nodes. This limits the possible use cases as it can't support sources that are more complex than a single subdev. To support more complex hardware pipelines, implement support for the media controller centric API. The exposed API can be selected through a module parameter. Signed-off-by:

Until now, the VP8 V4L2 API was not exported as a public API, and only defined in a private media header (media/vp8-ctrls.h). The reason for this was a concern about the API not complete and ready to support VP8 decoding hardware accelerators. After reviewing the VP8 specification in detail, and now that the API is able to support Cedrus and Hantro G1, we can consider this ready. Signed-off-by:

On production devices the firmware could be located on different places, this path could be provided by special firmware-name DT property. Here we check for existence of such DT property and if it exist take the firmware path from there. Otherwise, if the property is missing we fallback to the predefined path from driver resource structure. Signed-off-by:

Commit aaaa93ed ("media] media: venus: venc: add video encoder files") is the last in a series of three commits to add core.c vdec.c and venc.c adding core, encoder and decoder. The encoder and decoder check for core drvdata as set and return -EPROBE_DEFER if it has not been set, however both the encoder and decoder rely on core.v4l2_dev as valid. core.v4l2_dev will not be valid until v4l2_device_register() has completed in core.c's probe(). Normally this is never seen however, Dmitry reported the following backtrace when compiling drivers and firmware directly into a kernel image. [ 5.259968] Hardware name: Qualcomm Technologies, Inc.
