From c5005ab7c28f7b028822c8db7eb09ae1ac790e43 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Mon, 27 Nov 2023 14:50:58 +0000 Subject: [PATCH 0749/1085] 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.
