Subject: [PATCH 399/828] media: i2c: ov5647: Correct minimum VBLANK value
|
2021-11-24 17:32:01 +00:00
|
|
|
|
|
|
|
|
Trial and error reveals that the minimum vblank value appears to be 24
|
|
|
|
|
(the OV5647 data sheet does not give any clues). This fixes streaming
|
|
|
|
|
lock-ups in full resolution mode.
|
|
|
|
|
|
|
|
|
|
Fixes: 9b5a5ebedc303 ("media: i2c: ov5647: Add support for V4L2_CID_VBLANK")
