[PATCH v3 0/3] arm64: dts: qcom: Lenovo ThinkPad T14s Gen 7 (Mahua) support

[Srinivas Kandagatla]

Add support for the Lenovo ThinkPad T14s Gen 7 (Mahua), a Snapdragon X2
Elite laptop.  Patch 1 adds the board compatible under qcom,mahua and
follows the Gen 6 T14s pattern with distinct -lcd / -oled variants.
Patch 2 is the T14s Gen 7 (LCD) device tree itself; it follows the
Qualcomm Glymur reference design used by mahua-crd.  Patch 3 adds the
board to the QSEECOM allowlist, matching the pattern used for the Yoga
Slim 7x Gen 11, HP EliteBook X G2q 14 AI and Zenbook A14.

Currently working on the board: internal eDP display, WSA8845 speaker
playback and DMIC capture, DisplayPort audio on the two USB-C DP
outputs (DP0/DP1), USB-C (host + charging on both ports), WCN7850
Wi-Fi and Bluetooth, NVMe, HID-over-I2C touchpad / keyboard /
TrackPoint, lid switch, internal USB2 camera on usb_hs (via PTN3222
redriver) and Goodix fingerprint reader on usb_2.  WWAN wiring is
included but untested (no such SKU on hand).

Changes since v2 [1]:
 - Drop the panel-edp patch; the CSOT MNE007QB1-1 entry has landed
 - Enable internal USB2 camera on usb_hs (via PTN3222 redriver)
 - Enable Goodix fingerprint reader on usb_2
 - Picked up Reviewed-by: Konrad Dybcio on the DTS
 - Re-add the QSEECOM allowlist patch that was sent as 4/4 in v1 [2]
   and inadvertently dropped from v2
