Now that we've destaged the H264 stateless codec controls, and with all the pieces in place, update the documentation and move it to its own section. Signed-off-by:

The H.264 stateless 'uAPI' was staging and marked explicitly in the V4L2 specification that it will change and is unstable. Note that these control IDs were never exported as a public API, they were only defined in kernel-local headers (h264-ctrls.h). Now, the H264 stateless controls is ready to be part of the stable uAPI. While not too late, let's rename them and re-number their control IDs, moving them to the newly created stateless control class, and updating all the drivers accordingly. Signed-off-by:

For now, only print the type of the control. In the future, we might want to be able to print the values of all the stateless codec controls currently set in the control handler, which should be useful for debugging reasons. Signed-off-by:

Move the H264 stateless control types out of staging, and re-number them to avoid any confusion. Signed-off-by:

When V4L2_CTRL_TYPE_H264_PRED_WEIGHTS was added, adding a replace symbol directive in videodev2.h.rst.exceptions was missed. Now that the control type is destaged, it's important to fix this. Signed-off-by:

Since we are ready to stabilize the H264 stateless API, start by first moving the parsed H264 pixel format. Signed-off-by:

Check that all the fields that correspond or are related to a H264 specification syntax element have legal values. Signed-off-by:

Avoid including h264-ctrls.h, vp8-ctrls.h, etc, and instead just include v4l2-ctrls.h which does the right thing. This is in preparation for moving the stateless controls out of staging, which will mean removing some of these headers. Signed-off-by:

For historical reasons, stateful codec controls are named as {}_MPEG_{}. While we can't at this point sanely change all control IDs (such as V4L2_CID_MPEG_VIDEO_VP8_FRAME_HEADER), we can least change the more meaningful macros such as classes macros. Signed-off-by: -

Cedrus supports H.264 profiles from Baseline to High, except for the Extended profile Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE so that userspace can query the driver for the supported profiles and levels. Signed-off-by:

The Rockchip Video Decoder used in RK3399 supports H.264 profiles from Baseline to High 4:2:2 up to Level 5.1, except for the Extended profile. Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE and the V4L2_CID_MPEG_VIDEO_H264_LEVEL control, so that userspace can query the driver for the list of supported profiles and level. For now, we don't expose 4:2:2 since the driver doesn't implement the required support. [Ezequiel: Don't expose 4:2:2 profile for now] Signed-off-by:

Add a debug message for control validation (validate_new) failures. This is useful to debug issues with ioctls such as VIDIOC_TRY_EXT_CTRLS and VIDIOC_S_EXT_CTRLS. Signed-off-by:

V4L2_CTRL_CLASS_DETECT was never documented here, add it. Signed-off-by:

The VP8_FRAME_HEADER control type is validated, so it needs a corresponding initialization to produce default legal values. For now, only add the minimum required initialization to satisfy current validation. Signed-off-by:

Use regulators vio and vcore besides vana. The regulators were always there but on many boards they've been hard wired. Control them explicitly now. Signed-off-by:

Vcore and vio supplies are also part of the spec and used by many sensors. Do not specify the voltages as they are generally sensor dependent. Signed-off-by:

It was mentioned vana voltage is typically 2,8 volts. This is truly sensor dependent, and nowadays 2,8 volts is a lot. Signed-off-by:

Over the years (and renaming) some lines that may well be wrapped ended up being over 80 characters, likewise there are shorter lines that can be merged. Do that. Signed-off-by:

If pm_runtime_get_sync() fails, there's no need to set the device active again. Also, in the same case to return the usage_count to zero, pm_runtime_put_noidle() is enough. Signed-off-by:

MIPI CCS replaces SMIA and SMIA++ as the current standard. CCS brings new features while existing functionality will be supported. Rename the smiapp-pll as ccs-pll accordingly. Also add Intel copyright to the files. Signed-off-by:

Some limit values are available in q16.q16 format, referred to as 32-bit unsigned ireal in CCS. Read these correctly. Signed-off-by:

Instead of converting the limit values at register read time, do that at access time instead. Signed-off-by:

The limit values will be raw soon, and the conversion takes place later on. Prepare for that. Signed-off-by:

Rework quirk and 8-bit only access functions with a single function that takes arguments. This is later extensible to support yet more flags. Signed-off-by:

If an internal driver error was encountered, BUG was issued. Instead, do less harsh WARN_ON_ONCE and try to manage with the consequences. Signed-off-by:

The register arrays have a certain size but not all the entries will be relevant. In practice reading can be stopped after encountering a zero value in the array. Do that to avoid extra reads. Signed-off-by:

The module revision number major and minor are both 8 bits while the sensor revision number is 16 bits. Combine the module revision into one number. This also adds printing the lowest 8 bits of the module version through the sysfs attribute. Signed-off-by:

Add a parser library for parsing the CCS static data format. The library may be also compiled in user space as the format has uses also in the user space. Therefore it is dual licensed under the 3-clause BSD license as well. Signed-off-by:

Let v4l2_fwnode_endpoint_alloc_parse to figure out the type of the data bus. As the old bindings did not require the "bus-type" property, we need to rely on guessing between CSI-2 D-PHY and CCP2. Setting the type to CSI-2 D-PHY will parse just that and succeed even if no data-lanes are set. Also add a comment on the matter to the driver to avoid breaking this in the future. Signed-off-by:
