[PATCH 0/4] arm64: dts: qcom: Add Lenovo ThinkPad T14s Gen 7

[Srinivas Kandagatla]

Add device tree support for the Lenovo ThinkPad T14s Gen 7 [1], a Mahua
(Snapdragon X2 Elite) laptop, together with the drm/panel-edp entry
for its internal panel and a QSEECOM allowlist entry.

Tested on the platform:
  - Display (internal eDP and external DP on both USB-C ports)
  - USB-C data + charging on both ports
  - Wi-Fi (WCN7850) and Bluetooth
  - NVMe on PCIe5
  - HID-I2C touchpad, keyboard, TrackPoint, lid switch
  - Audio playback (2x WSA8845 speakers) and capture (DMICs)
  - ADSP / CDSP / SoCCP

Not tested / out of scope:
  - WWAN (wiring included but no SKU with the modem to test)
  - GPU / GMU (kept out of scope for this bring-up)

my working tree is: https://github.com/Srinivas-Kandagatla/linux/tree/upstream/t14s-Gen7
alsa ucm is in : https://github.com/Srinivas-Kandagatla/alsa-ucm-conf/tree/t14s-gen7

I plan to enable DP audio and other things in parallel.

Depends on Bjorn's:
  - phy: qcom: edp: split power-on sequencing by PHY version
  - phy: qcom: edp: update v8 power-on programming sequence
