From d9bad36a8f7530ec17ffe93521a8a71bc1e54a20 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Thu, 15 Dec 2022 16:15:27 +0000 Subject: [PATCH] dt: Add camX_reg and camX_reg_gpio overrides to CM4S CM4S follows the pattern of CM1&3 for routing camera GPIO control, but didn't have the overrides defined to allow enabling and configuring the camera regulator GPIOs. Add them.
