[PATCH 5/6] arm64: dts: freescale: imx8m{m,p}-verdin: Add shared OV5640 overlays
From: Ernest Van Hoecke
Date: Thu Sep 10 2026 - 11:59:42 EST
From: Ernest Van Hoecke <ernest.vanhoecke@xxxxxxxxxxx>
The current and legacy Toradex OV5640 camera modules use the same connector
on Verdin iMX8M Mini and Verdin iMX8M Plus. Keeping SoC and carrier GPIO
references in the overlays would require a separate camera description for
every combination.
Use the connector nexus and stable CSI_1 media labels to describe the
camera once. Keep separate variants only for the current 27 MHz and legacy
24 MHz camera oscillators.
Build both DTBOs for installation and compose each with the two Verdin
Development Board DTBs to validate the module integrations.
