Date: Tue, 20 Oct 2020 17:45:21 +0200 Message-Id: <20201020154522.654-1-dafna.hirschfeld@collabora.com> X-Mailer: git-send-email 2.17.1 Precedence: bulk List-ID: X-Mailing-List: linux-media@vger.kernel.org MEDIA_BUS_FMT_METADATA_FIXED should be used when the same driver handles both sides of the link and the bus format is a fixed metadata format that is not configurable from userspace. The width and height will be set to 0 for this format. Signed-off-by: Dafna Hirschfeld Acked-by: Helen Koike --- changes since v1: 1. replace "This format may have 0 height and width." with "Width and height will be set to 0 for this format." and add it also to the commit log 2. s/meida:/media:/ in the patch subject line include/uapi/linux/media-bus-format.h | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/include/uapi/linux/media-bus-format.h b/include/uapi/linux/media-bus-format.h index 84fa53ffb13f..2ce3d891d344 100644 --- a/include/uapi/linux/media-bus-format.h +++ b/include/uapi/linux/media-bus-format.h @@ -156,4 +156,12 @@ /* HSV - next is 0x6002 */ #define MEDIA_BUS_FMT_AHSV8888_1X32 0x6001 +/* + * This format should be used when the same driver handles + * both sides of the link and the bus format is a fixed + * metadata format that is not configurable from userspace. + * Width and height will be set to 0 for this format. + */ +#define MEDIA_BUS_FMT_METADATA_FIXED 0x7001 + #endif /* __LINUX_MEDIA_BUS_FORMAT_H */
