This bug is awaiting verification that the linux-xilinx- zynqmp/5.15.0-1034.38 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-done-jammy-linux-xilinx-zynqmp'. If the problem still exists, change the tag 'verification-needed-jammy-linux-xilinx-zynqmp' to 'verification-failed-jammy-linux-xilinx-zynqmp'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[ 72.628992] imx547 7-001a: imx547 : imx547 probe success ! On second load: ubuntu@kria:~$ sudo dmesg | grep imx547 [ 312.319586] imx547 7-001a: GT TRX Reset GPIO not setup in DT [ 312.325487] imx547: probe of 7-001a failed with error -16 * New implementation of using device managed ie devm_* functions ensures that resource is automatically removed when driver is unloaded. [ Test Plan ] * Xilinx will verify the functionality when testing kernel is provided. [ Where problems could occur ] * Since freeing of the GPIO resource is not explicitly handled in current implementation the driver fails to probe the sensor and fails to add it to media subsystem.
