From 052a9ff245fe1192cf007c9246a215c897535e78 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Wed, 23 Oct 2024 09:01:18 +0200 Subject: include: linux: Update headers for line-based embedded data support Update the kernel headers with the definition of two device-specific line-based metadata formats, and with the definition of the MEDIA_PAD_FL_INTERNAL and V4L2_SUBDEV_ROUTE_FL_IMMUTABLE flags. The new definitions will allow to support handling line-based metadata streams exposed by the sensor driver through an internal sink pad. While the changes have not yet been collected in the official linux-media tree, they're available in the 'metadata' branch of https://git.linuxtv.org/sailus/media_tree.git, at revision: f9bbbd9a696d ("media: Documentation: Add binning and sub-sampling controls") Signed-off-by: Jacopo Mondi Acked-by: Kieran Bingham --- include/linux/README | 2 +- include/linux/media-bus-format.h | 4 ++++ include/linux/media.h | 1 + include/linux/v4l2-subdev.h | 5 +++++ 4 files changed, 11 insertions(+), 1 deletion(-) diff --git a/include/linux/README b/include/linux/README index ef178681..f9f68641 100644 --- a/include/linux/README +++ b/include/linux/README @@ -1,4 +1,4 @@ # SPDX-License-Identifier: CC0-1.0 -Files in this directory are imported from next-media-rkisp1-20240814-14-ga043ea54bbb9 of the Linux kernel.
