** Description changed:
+ [SRU Justification]
+
+ [ Impact ]
+
+ Sony imx471 is not explicitly powered on before trying to identify the
module, leaving following error messages in kernel dmesg buffer:
+ ```
+ kernel: imx471 i2c-SONY471A:00: failed to find sensor: -5
+ kernel: imx471 i2c-SONY471A:00: probe with driver imx471 failed with error -5
+ ```
+
+ Proposed fix in
+
https://github.com/intel/ipu6-drivers/commit/faef397c5bfedcd3182cce27eab1539f5eaca9eb.
+
+ [ Test Plan ]
+
+ 1. Install the dkms from -proposed pocket. The corresponding binary kernel
module should be built automatically; if not, run:
+ ```
+ $ sudo dkms install --force ipu6-drivers/0~git202506270118.9bff7368 -k
$(uname -r)
+ ```
+
+ 2. Reboot to the same kernel to reload the drivers.
+
+ 3. Make sure the device is probed and up running:
+ ```
+ $ media-ctl -p
+ Media controller API version 6.14.8
+
+ Media device information
+ ------------------------
+ driver intel-ipu7
+ model ipu7
+ serial
+ bus info PCI:intel-ipu7
+ hw revision 0x17aa233b
+ driver version 6.14.8
+ ...
+ ```
+
+ 4. Use https://webcamtests.com to verify the camera is really capable of
+ streaming.
+
+ [ Where problems could occur ]
+
+ This fills the probe procedure as other similar camera sensors do. No
+ known problem so far.
+
+ [ Other Info ]
+
+ This is a follow-up for bug 2107320 that supports IMX471 in linux-
+ oem-6.11 and on. Nominate for Plucky, Questing for ipu6-drivers, which
+ will be compiled within linux-oem-6.11 and on.
+
