[PATCH 4/6] arm64: dts: freescale: imx8m{m,p}-verdin: Add camera connector nexus
From: Ernest Van Hoecke
Date: Thu Sep 10 2026 - 11:47:47 EST
From: Ernest Van Hoecke <ernest.vanhoecke@xxxxxxxxxxx>
The Verdin Development Board, Dahlia and Mallow expose the same 24-pin CSI
camera connector, while Verdin iMX8M Mini and Verdin iMX8M Plus route its
sideband signals and media pipeline through different SoC resources.
Add a GPIO nexus to each carrier description and stable Verdin-level labels
for each module's CSI_1 I2C bus, receiver and capture engine. Keeping the
nexus in the carrier files avoids describing the physical connector on
carriers which do not provide it.
This gives accessory overlays a stable connector and media interface
without embedding either module's wiring in the accessory description.
