Hi Folks,

This is a new revision of

https://lore.kernel.org/linux-acpi/2187487.irdbgypaU6@kreacher/

addressing comments from Sakari and adding one more patch (also from
Sakari).

The main points from the original cover letter are still valid:

> The general idea is the same - CSI-2 resource descriptors, introduced in
> ACPI 6.4 and defined by
>
> https://uefi.org/specs/ACPI/6.5/06_Device_Configuration.html#camera-serial-i
> nterface-csi-2-connection-resource-descriptor
>
> are found and used for creating a set of software nodes that represent the
> CSI-2 connection graph.
>
> These software nodes need to be available before any scan handlers or ACPI
> drivers are bound to any struct acpi_device objects, so all of that is done
> at the early stage of ACPI device enumeration, but unnecessary ACPI
> namespace walks are avoided.
>
> The CSI-2 software nodes are populated with data extracted from the CSI-2
> resource descriptors themselves and from device properties defined by the
> MIPI DisCo for Imaging specification (see
> https://www.mipi.org/specifications/mipi-disco-imaging).
>
> Patches [4,6/6] come from the original series directly, but the other
> patches have been changes substantially, so I've decided to re-start patch
> series versioning from scratch.

The series is based on the current mainline.

Thanks!
