I would say that "The buffer contains a single instance of the C structure :c:type:`rkisp1_isp_params_cfg`, defined in the ``linux/rkisp1-config.h`` header file." And add a sentence to explain what the alignment requirements are. > + > +The parameters consist of multiple modules. > +The module won't be updated if the corresponding bit was not set in module_*_update. Doesn't this belong to rkisp1-config.h ? I would group all the information related to fields of the structure in the header file, and only have here the information related to the buffer layout (this mainly referencing the structure and talking about alignment/padding). > + > +.. kernel-doc:: include/uapi/linux/rkisp1-config.h > + :functions: rkisp1_isp_params_cfg > diff --git a/Documentation/media/uapi/v4l/pixfmt-meta-rkisp1-stat.rst b/Documentation/media/uapi/v4l/pixfmt-meta-rkisp1-stat.rst > new file mode 100644 > index 000000000000..4ad303f96421 > --- /dev/null > +++ b/Documentation/media/uapi/v4l/pixfmt-meta-rkisp1-stat.rst > @@ -0,0 +1,22 @@ > +..
