Subject: [PATCH 0/3] Add x1e Dell Inpsiron 14p

Add in a dtsi for the Dell Inspiron 14p.

I'm currently using this as a daily driver including sending this series
from. Its reasonably stable on 6.15-rcX.

The first two patches can be applied without dependency, the final patch
relies on patches staged for -next in the media tree to be applied,
presently.

Working for me included in this series:

- USB
  Both Type-C USB ports
  Type-A port
  Fingerprint reader
- WiFi
- Bluetooth
- RGB Camera
- Toucpad, keyboard
- Display

Working for me but not included:
- Audio jack
- Iris

Not working:
- Speaker output
  Still WiP haven't touched this in a while

- Battery
  Dell has its own Embedded Controller likely from the x86 platform reused
  on Qcom which we need to reverse engineer or get some information on to
  make faster progress on.

- cDSP
  Haven't tried to bring this up.

- EVA
  No driver haven't tried it.

- Bugs
  Occasionally when resuming I get a fencing error with hyperlock and
  freedreno, TBH it looks like something in the GPU or SMMU according to
  Rob Clark: https://pastebin.com/AWjCyaap

  Ath12k has been splatting for me up to 6.14 when removing a SSID.
  I switched on ath12k debug when going to 6.15 and predictably couldn't
  reproduce the bug, either because the timings have changed as a result
  of Heisenbugging or because a fix has been slipped into ath12k.

  Other than those two I'm pretty happy with this system.

  The DTS is based on Aleksandrs Vinarskis XPS, Lenovo T14s and Qcom CRD.
