[PATCH v2 0/4] Add NVL CVS/IPU8 camera support

[Arun T]

This series adds NVL CVS support to the ACPI dependency handling,
the IPU bridge, and the CVS driver. It also adds the IPU8 PCI device
ID needed for the CVS driver to bind on NVL camera hardware.

Changes in v2:
- Add a cover letter for the multi-patch series.
- Add Reviewed-by from Sakari Ailus to patch 1.

[PATCH v2 1/4] ACPI: scan: Honor ACPI _DEP dependency for NVL CVS

[Arun T]

Add INTC10FA to the ACPI dependency honor list so the CVS driver is
loaded before dependent camera devices are probed on NVL platforms.

This matches the camera dependency handling already used for IVSC-based
platforms and ensures the camera streaming path is initialized before
sensor access or pipeline setup depends on it.

unless you want me to apply this patch, in which case please let me
know.  Otherwise, I'll assume it to go in via the media tree.

Thanks!

[PATCH v2 2/4] media: pci: ipu-bridge: Add NVL CVS ACPI ID

[Arun T]

Add INTC10FA to the IPU bridge ACPI match table so the bridge can
recognize NVL CVS devices.

This enables the camera bridge path to bind on NVL platforms where the
CVS device is exposed through the INTC10FA ACPI ID.

There's no need to send further versions of these patches; patches 2--4 are
already in my tree.
