[PATCH 2/2] arm64: dts: freescale: imx8mp-toradex-smarc: Add OV5640 overlays

From: Ernest Van Hoecke

Date: Fri Oct 02 2026 - 09:33:43 EST

From: Ernest Van Hoecke <ernest.vanhoecke@xxxxxxxxxxx>

Add device tree overlays for the current 27 MHz and legacy 24 MHz
Toradex OV5640 camera modules connected to CSI0 and CSI1 on the SMARC
Development Board.

CAM_n_CON_PWRCTRL (pin 24) is an active-high power-up input of the
camera module, so it is described as an active-low powerdown GPIO.

The overlays are also combined with the SMARC Development Board device
tree to provide ready-to-use DTBs.
