Not working on Dell Pro Plus 14, PB14250

Hi,

I have a Dell Pro Plus 14 laptop (model PB14250), with built-in "5MP HDR + IR Camera" (Dell part 319-BBJW).
This is a Lunar Lake system with an Ultra 7 268V.
The camera works out of the box in Windows 11, but is not detected in Fedora 42.
I have tried the following steps to get it to work:

1) Install the code from the 4 IPU7 repositories here.
After loading the ipu7 kernel module, I get "no subdev found in graph", as per #17 .

2) The Windows driver for the camera seems to be 70.26100.2.18597.
Downloading the relevant file from [here](https://www.catalog.update.microsoft.com/Search.aspx?q=Intel%28R%29+AVStream+Camera) shows it contains hm1092 and ov05c10.

3) The ov05c10 is not listed in ipu-bridge.c. Following the suggestion from [here](https://github.com/intel/ipu7-drivers/issues/17#issuecomment-2544408786), I patched ipu-bridge.c to add it, as per this [Ubuntu](https://kernel.ubuntu.com/forgejo/kernel/noble-linux-oem/pulls/53) patch.

I now get

> intel-ipu7: Found supported sensor OVTI05C1:00
> intel-ipu7: Connected 1 cameras

but the camera still does not work. The relevant errors seem to be:

> int3472-discrete INT3472:00: cannot find GPIO chip INTC10B5:00, deferring
> int3472-discrete INT3472:00: GPIO type 0x02 unknown; the sensor may not work

The second one resembles this IPU6 [issue](https://github.com/intel/ipu6-drivers/issues/281), but has a different address.

I attach some files with possibly relevant info.

Thanks in advance for any help with this.
