Subject: [PATCH] dtoverlays: Correct CSI2 settings for ov9281
|
||
|
|
|
||
|
|
OV9281 appears to drop the clock to LP mode between frames, but
|
||
|
|
the overlay didn't define this at both ends of the CSI2 link.
|
||
|
|
The overlay also had an incorrect link frequency defined, not that
|
||
|
|
the driver ever checked for one.
|
||
|
|
|
||
|
|
Fix both issues.
