Add preliminary support for the Surface Pro 8 to the Surface Aggregator
registry. This includes battery/charger status and platform profile
support.
In contrast to earlier Surface Pro generations, the keyboard cover is
now also connected via the Surface Aggregator Module (whereas it was
previously connected via USB or HID-over-I2C). To properly support the
HID devices of that cover, however, more changes regarding hot-removal
of Surface Aggregator client devices as well as a new device hub driver
are required. We will address those things in a follow-up series, so do
not add any HID device IDs just yet.

Since it is just device-id additions I can still pick this up for
5.16 if you want / if this is useful.
Do you want me to pick this up for 5.16 ?

Hmm, usefulness is somewhat limited, because the device currently has
neither touchscreen nor keyboard cover support, so external peripherals
are required.
I think including it might still be a good idea though because it at
least makes that scenario somewhat viable by providing battery stats.
Thanks,
Max

Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
