Subject: [PATCH] dtoverlays: Add option for cam0 to camera-mux-Nport overlays
|
||
|
|
|
||
|
|
Seeing as the mux can be connected to either CAM/DISP1 or
|
||
|
|
CAM/DISP0 on a Pi5, add a cam0 override to allow configuration
|
||
|
|
of which is used. Default (as with all camera overlays) is CAM/DISP1.
|
||
|
|
|
||
|
|
The overlay does NOT update the camera regulator used by all the
|
||
|
|
sensors as doing so would be a nightmare. The Arducam mulitplexer
|
||
|
|
boards these overlays are initially supporting seem to tie the
|
||
|
|
regulator GPIO for all the sensors high anyway.
|
||
|
|
If it was viewed as necessary, then creating an additional
|
||
|
|
regulator that listed cam[01]_reg as the parent should work.
|
||
|
