+Subject: [PATCH] media: pixfmt: Document the HEVC slice pixel format
+
+Commit de06f289283298e2938445019999cec46435375c upstream.
+
+Document the current state of the HEVC slice pixel format.
+The format will need to evolve in the future, which is why it is
+not part of the public API.

++	This pixelformat has two modifiers that must be set at least once

++        and ``V4L2_CID_MPEG_VIDEO_HEVC_START_CODE`` controls.
