[SRU][O/P][PATCH 00/27] Add Intel Touch Host Controller drivers

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/2096624

[Impact]
The new touchscreen on Intel LNL is lack of driver support.

00:10.0 Digitizer Pen [0901]: Intel Corporation Device [8086:a848] (rev 10)

[Fix]
Enable Intel THC driver to support it.

[Test]
Tested on hardware, multi-touch works fine on Wacom and Goodix touchscreens.

[Where problems could occur]
It introduces a brand new driver, may break hid functions.

Because this is a new feature driver, SRU for oracular/plucky/oem-6.11.
