From 9c68ba121ba173dd5711b4537bfcdf82ec731725 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Wed, 3 Apr 2024 16:08:07 +0100 Subject: [PATCH 1040/1085] dt: Add camX_sync option to configure a GPIO following cam FS/FE Unicam now takes an optional GPIO to expose frame start/end timing, so add an override to configure that.
