[PATCH] media: ipu-bridge: Add upside-down sensor quirk for Dell 16 Premium DA16250

[Lukas Larson]

On the Dell 16 Premium DA16250 laptop, the camera sensor (OVTI02C1) is
mounted upside-down, resulting in a flipped image in userspace
applications.

Add this model to the upside_down_sensor_dmi_ids list to provide the
necessary 180-degree rotation quirk so the image is oriented correctly.

Hi Lukas,

Thanks for the patch.

Could you try if these
<URL:https://git.linuxtv.org/sailus/media_tree.git/log/?h=pld> fix your
issue as well?

There are a bunch of Dell laptops with this sensor and only some of them
need this quirk...

There seems to be another problem here. :-(

You'll also need at least another patch, "media: v4l: fwnode: Support
ACPI's _PLD for v4l2_fwnode_device_parse", in order for this to work. I've
rebased the patches on plain v6.19 and pushed that to the pld branch. Would
you be able to test this again?

Hi Sakari,

On pld 6.19 the camera powered on, but the image was flipped upside down.
Tested adding https://github.com/intel/ipu6-camera-bins and
https://github.com/intel/ipu6-drivers, still upside down.

Some logs from pld:

Ack. Thanks for confirming this.

I think what has happened is that the sensor's orientation was originally
baked into the register lists and once that was fixed, we run into the
issue. But it still appears that some systems with this sensor have it
mounted upright, or at least SSDB has correct information about it.

I'll take this for v7.2.
