Subject: [PATCH v4 2/2] media: uvcvideo: Add D436 and D555 cameras metadata
 support

From: ymodlin <yogev.modlin@...lsenseai.com>

Add support for Intel RealSense D436 and D555 depth cameras metadata.
These cameras use the D4XX metadata format for transmitting depth and
sensor information.

The D555 camera uses UVC protocol version 1.5, while the D436 uses
an undefined protocol version. Both cameras require the D4XX metadata
format flag to properly handle their metadata streams.
