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

Add lenovo,thinkpad-t14s-gen7 as a board compatible under qcom,mahua.
The T14s Gen 7 uses the Mahua SoC (a 12-core variant of Glymur with
cluster2 / cpu12-cpu17 fused off) rather than Glymur proper, matching
what the platform's ACPI MADT dump reports (12 enabled + 6 disabled
processors).

Introduce a device tree for the Mahua-based Lenovo ThinkPad T14s Gen 7,
a Snapdragon X2 Elite laptop. It follows the Qualcomm Glymur reference
design used by mahua-crd.
Currently working:
- Display (internal eDP panel)
- Audio playback and capture (2x WSA8845 speakers on swr0, DMICs via
the VA macro)
- DisplayPort audio on the two USB-C DP outputs (DP0/DP1)
- USB-C (host + charging on both ports)
- Wi-Fi (WCN7850 on PCIe4), Bluetooth (over uart14)
- NVMe on PCIe5
- HID-over-I2C touchpad, keyboard and TrackPoint on i2c0
- Lid switch
- Internal USB2 camera on usb_hs (via PTN3222 redriver)
- Goodix fingerprint reader on usb_2
- WWAN wiring is included but remains untested due to lack of access
to such a SKU.

Allow the use of QSEECOM on the Mahua-based Lenovo ThinkPad T14s Gen 7,
matching the pattern established for the Yoga Slim 7x Gen 11.

commit c99537659e637d229456f818bb7c8fc0b3d7fcf3
Author: Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com>
arm64: dts: qcom: Add Lenovo ThinkPad T14s Gen 7
Introduce a device tree for the Mahua-based Lenovo ThinkPad T14s Gen 7,
a Snapdragon X2 Elite laptop. It follows the Qualcomm Glymur reference
design used by mahua-crd.

[Severity: High]
Could this GPIO assignment conflict with ptn3222_1 above?
The ptn3222 driver requests the reset GPIO exclusively during probe via
devm_gpiod_get_optional(dev, "reset", GPIOD_OUT_HIGH). Because the GPIO
subsystem prevents sharing an exclusive GPIO by default, assigning the same
GPIO to both redrivers could cause one of them to deterministically fail to
probe with a -EBUSY error.

[Severity: Medium]
Will this cause visual artifacts during boot or resume?
It appears the backlight enable GPIO (tlmm 18) is passed here as the panel's
logic power enable. The panel-edp driver asserts enable-gpios in
panel_edp_prepare_once() before the eDP link is trained and valid video data
is streaming. Bypassing proper eDP DPCD and backlight sequencing could turn
the backlight on prematurely.

that is correct, I ended up sending some stale patches. will be fixed in v5.

this is same across other glymur dts.
