Subject: [PATCH 0798/1085] overlays: Add "always-on" parameter to imx477 and
|
||
|
|
imx296
|
||
|
|
|
||
|
|
Leave the camera's power supplies up, to prevent the camera
|
||
|
|
clamping its 1.8V digital I/Os to ground. This may be useful
|
||
|
|
when synchronizing multiple camera systems using XVS or XTRIG.
|
||
