[RFC PATCH 3/3] media: imx219: Add support for multiplexed streams
Jean-Michel Hautbois
jeanmichel.hautbois at ideasonboard.com
Wed Jan 12 09:27:20 PST 2022
As of now, imx219 was not supporting anything more than one stream. Add
support for embedded data, based on linux-rpi kernel, and make it work
with multiplexed streams. We have only one source pad with two streams:
stream 0 is the image, and stream 1 is the embedded data.
