Subject: [RFC PATCH 00/12] media: ov5645: Add support for streams
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
Hi All,
This patch series aims to add the below features,
- Support subdev active state
- Support for streams
- Support for virtual channel
- Code cleanup
Sending this is as an RFC, I've done limited testing and Im seeing issue
when route is updated and wanted some feedback on the implementation.
When route is updated for the sensor with below command, and when start
streaming I get "Dangling sink streams: mask 0x1" error. Should the
corresponding bridge also need to support routes to fix this? or is it
something missing Ive missed in the current implementation.
$ media-ctl -R "'ov5645 0-003c' [1/0->0/1[1]]"
Output after route update:
- entity 4: ov5645 0-003c (2 pads, 1 link, 1 route)
type V4L2 subdev subtype Sensor flags 0
device node name /dev/v4l-subdev1
routes:
1/0 -> 0/1 [ACTIVE]
pad0: SOURCE

crop:(0,0)/1920x1080]
