[Bug 2093269] Re: [X1E] Support HP EliteBook Ultra G1q 14

[No Such Thing As Cloud]

Ignoring the fact I cannot compile a working kernel, I have made
additional progress.

- Sound works!
- PD-Mapper Works!

I made a provisioning script to help get all the needed firmware in the right place from a clean install state:
https://codeberg.org/nosuchthingascloud/x1e80100-hp-elitebook-ultra-g1q/src/branch/main/setup_elite.sh

What still needs fixing:
- Custom Kernel builds
- Webcam support (seems to be the driver is failing, I went all out on the .dts and it should work)

Title:
  [X1E] Support HP EliteBook Ultra G1q 14

Status in ubuntu-concept:
  Confirmed
Status in linux package in Ubuntu:
  In Progress

Bug description:
  Add support for the Snapdragon X Elite powered HP EliteBook Ultra G1q
  14

  === Device Information ===
  Manufacturer: HP
  Product Name: HP EliteBook Ultra G1q 14 inch Notebook AI PC
  Version: ConfigID
  Wake-up Type: Power Switch
  SKU Number: A37B0ET#UUW
  Family: 103C_5336AN HP EliteBook Ultra

  === Notes ===

  No keyboard in GRUB on USB boot.
  Boot loop using default ISO.
  Added the following to grub using livefs-edit and I am able to boot and install. Using devicetree from OmniBook seems to work well enough to get started.

  regexp "HP EliteBook Ultra G1q 14.*" "$system_product_name"
  if [ $? == 0 ]; then
          cmdline="clk_ignore_unused pd_ignore_unused cma=128M "
          dtb="devicetree /casper/dtbs/x1e80100-hp-omnibook-x14.dtb"
  fi

  After running qcom-firmware-extract I have a working system with -it
  seems- pretty much the same issues as OmniBook.

  Keyboard is OK in installed GRUB.

  === What does not work ===
  Internal speakers
  Internal webcam
  Bluetooth detects and pairs but unable to connect (will troubleshot this some more with other devices).
  Function keys
  Brightness full on around 95% (in gnome), if I go above it it "starts over"

  Not sure about suspend yet, will leave it suspended and check battery
  drain tomorrow

  I am happy to provide more details.
