* Recycling of megous v5.16.4 patches The patches were sorted as far as possible. Some patches are renamed according to their place of application. The length of the patch name has been changed to improve readability using the `git format-patch --filename-max-length=75` method. The folder containing the patches will have the name `patches.name` and the corresponding file `series.name` for the convenience of processing and moving them upstream. But the control file remains `series.conf`.

Subject: [PATCH 043/101] Doc:u-api:media:v4l: Add scaling matrix control
|
|
|
|
HEVC scaling lists are used for the scaling process for transform
|
|
coefficients.
|
|
V4L2_HEVC_SPS_FLAG_SCALING_LIST_ENABLED has to set when they are
|
|
encoded in the bitstream.
