Summary

  • Adds tegra234-p3767-camera-p3768-ar0234-dual.dts overlay for JAJ and PAB_V3
  • Uses onsemi,ar0234 driver (nv_ar0234.ko) with p3768 GPIO I2C mux pattern
  • Shows as "Camera AR0234 Dual" in jetson-io under "Jetson 24pin CSI Connector"
  • Modeled after the IMX477 dual overlay, with AR0234 sensor properties from the existing hawk dtsi

Test plan

  • Build JAJ target and verify tegra234-p3767-camera-p3768-ar0234-dual.dtbo is in output
  • Flash JAJ, confirm "Camera AR0234 Dual" appears in config-by-hardware.py -l
  • Apply overlay, connect AR0234 sensor, verify streaming with v4l2-ctl

Uses the onsemi,ar0234 driver with the p3768 GPIO I2C mux pattern.
Enables "Camera AR0234 Dual" in jetson-io for JAJ and PAB_V3 builds.

This doesn't work. The AR0234 drivers included in the stock BSP are dedicated to the Hawk module (driver expects MAX96712 GMSL deserializer)
