Subject: [PATCH 0/2] Add device tree for MT8188-based Chromebook "Ciri"

Hi maintainers,

This series introduces the device trees for Ciri, a MT8188-based
Chromebook, commercially known as the Lenovo Chromebook Duet (11", 9).

Ciri is a detachable device based on the ChromeOS Geralt reference
design, where Geralt is the codename for the MT8188 platform. Ciri has 8
SKUs to accommodate the combinations of second-source components,
including audio codecs, speaker amplifiers, and MIPI-DSI panels.

The Geralt design is not used in any actual products, so its device tree
is not included.

The device trees are taken from the ChromeOS downstream v6.1 kernel,
ported to the mainline kernel and with cleanups. This series aims to
provide a basic device tree with the enabled components and features.
Additional support will be added in the future after validation with
the mainline kernel.

This series has been tested on top of the next-20241018 branch.

Patch 1 adds entries for Ciri in the MediaTek DT binding.
Patch 2 adds the dtsi files for Geralt and Ciri, followed by 8 dts files
for all the available Ciri SKUs at this moment.

Note that there are some known dtbs_check warnings, depending on binding
fix or driver support:
- sound: Unevaluated 'xxx-dai-link' properties: sent patch[1]
- amplifier '#sound-dai-cells' and other errors: sent patch[1]
- dp-tx '#sound-dai-cells' error: sent patch[2]
- failed to match 'himax,hx83102j': depend on HX83102J support[3]
