The V4L2_PIX_FMT_BGRA444 format has a comment that explains why its 4CC value is GA12. This explains the development history and isn't of much interest to readers, it should have been part of a commit message instead. Drop the comment, anyone interested in history can turn to git. Signed-off-by:

There is no intialization for the 'reg' variable, so printing it produces undefined behavior as well as a compile-time warning: drivers/media/i2c/ccs/ccs-core.c:314:49: error: variable 'reg' is uninitialized when used here [-Werror,-Wuninitialized] "0x%8.8x %s pixels: %d %s (pixelcode %u)\n", reg, Remove the variable and stop printing it.

Clang points out that the error handling in ov02a10_s_stream() is broken, and just returns a random error code: drivers/media/i2c/ov02a10.c:537:6: warning: variable 'ret' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] if (ov02a10->streaming == on) ^~~~~~~~~~~~~~~~~~~~~~~~ drivers/media/i2c/ov02a10.c:568:9: note: uninitialized use occurs here return ret; ^~~ drivers/media/i2c/ov02a10.c:537:2: note: remove the 'if' if its condition is always false if (ov02a10->streaming == on) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If streaming is already on, leave it that way and return success.

This reverts commit f61eb7bc. While aligning with the OF graph schema will be done for the media DT bindings, this patch got merged a little too hastily. Revert it for now. Suggested-by:

With Sphinx 2.x: those two warnings are produced: /devel/v4l/docs/sphinx2/Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-meta-fmt-rk-isp1-params (if the link has no caption the label must precede a section header) /devel/v4l/docs/sphinx2/Documentation/output/videodev2.h.rst:6: WARNING: undefined label: v4l2-meta-fmt-rk-isp1-stat-3a (if the link has no caption the label must precede a section header) The reason is that there's no blank line between the two identifiers.

Move the documentation for the stateless FWHT codec to ext-ctrls-codec-stateless.rst since that is the proper place for the stable stateless API documentation. Signed-off-by:
-
Hans Verkuil authored
The FWHT 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 (fwht-ctrls.h). Now, the FWHT stateless controls is ready to be part of the stable uAPI. While not too late: - Rename V4L2_CID_MPEG_VIDEO_FWHT_PARAMS to V4L2_CID_STATELESS_FWHT_PARAMS. - Move the contents of fwht-ctrls.h to v4l2-controls.h. - Move the public parts of drivers/media/test-drivers/vicodec/codec-fwht.h to v4l2-controls.h. - Add V4L2_CTRL_TYPE_FWHT_PARAMS control initialization and validation. - Add p_fwht_params to struct v4l2_ext_control.

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:

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:

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: -

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:

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:
