Add initial device tree for Acer Swift SFA14-11 laptop based on Qualcomm X1E78100 SoC.
Generated based on x1e78100-lenovo-thinkpad-t14s.dts.
Adjusted node ordering according to review feedback.
Passed format checks and successfully built without errors.

These look directly copypasted from the Lenovo DT, so I have concerns

This laptop seems to have 2 USB-A ports and no fingerprint/SDCard reader,
are you sure all of these are present onboard?

I don't see a HDMI port on this laptop
Moreover, I'm highly concerned about the regulator settings, which
differ between boards and may lead to permanent hardware damage if
misconfigured. If you took the values from the T14s DT as-is, you
may be doing yourself a bad favor..

R：
I have reviewed the DTS files for two other Acer models in the same series submitted by other contributors, and they all directly utilize certain drivers for the T14s.
Due to the lack of official support from Acer, removing the "lenovo,thinkpad-t14s" node will likely cause some hardware components to malfunction.

R：
It has at least been tested on the physical device. Due to my lack of professional expertise, making excessive modifications rashly would be more likely to cause hardware damage. To be clear, when booting the sfa14-11 with the T14s DTB under Linux, the power consumption and heat generation are both more severe compared to WOA. However, based on what I’ve learned from the Ubuntu community, this is likely an issue with the Qualcomm power management driver itself.

R: Thank you for your careful review. I believe that currently, with the exception of a few specific laptop models (e.g., the ThinkPad T14s), all other laptops utilizing the X1 Elite/Plus SoC experience more or less issues when running Linux on ARM—and the SFA14-11 is no exception. That said, I hope to raise its visibility and improve it through my efforts.

This is plainly untrue. The T14s is not special in any regard, and there
doesn't exist any sort of ""T14s drivers"" for the X1 SoC.
If you came up with this reasoning, grep for the T14s compatible string
in the kernel and convince yourself that's not the case.
If an LLM suggested this, it's hallucinating, very badly.

Then unless there's something else dangling off the USB bus, not all of
these redrivers are physically present.

I understand your position, however due to you admitting you're just
copypasting things and hoping they work, we can not accept this submission

I don't think that's the case, see this image from Acer. Unless the
SKU that they sell in Europe is different, with the same model number..

Your reply doesn't at all address my serious concern stated above.
Konrad
Here is the complete content of the email: My current capability only allows me to achieve this much. I have to temporarily give up on pushing for support for this model and hope that other professionals can continue this work. Additionally, the image in your reply is of the sf14-11, whereas the model I requested support for is the sfa14-11.https://gwcache.acer.com.cn/uploads/server/6e8f06d1d8884dd5136d82b91fdf284d.jpg The differences between these two models are significant: the display, CPU, USB, and other peripherals are all different. Currently, it appears that the sfa14-11 is only sold in mainland China.

No, it does not "Passed format checks" because it has inconsistent white
