Subject: [PATCH v2 2/6] media: media.h: Add new media link type
Date: Sun, 30 Jan 2022 23:58:17 +0000 [thread overview]
Message-ID: <20220130235821.48076-3-djrscally@gmail.com> (raw)
In-Reply-To: <20220130235821.48076-1-djrscally@gmail.com>
To describe in the kernel the connection between devices and their
supporting peripherals (for example, a camera sensor and the vcm
driving the focusing lens for it), add a new type of media link
to introduce the concept of these ancillary links.
Signed-off-by: Daniel Scally <djrscally@gmail.com>

Changes since v1:
- None
changes since the rfc:
- Split out into its own patch (mostly so it can be followed by patch
#3, which corrects some media-core code that is otherwise broken by the
new links)
