Subject: [PATCH v7 0/3] arm64: dts: qcom: x1-hp-x14: Add support for
 X1P42100 HP Omnibook X14

This patch series adds support for the HP Omnibook X Laptop 14-fe1xxx. [1]

Since this is actually the same model as the 14-fe0xxx, but with an
X1P-42-100 SoC (Purwa), it needs a slightly different device tree.
To have as minimal duplicate definition as possible, the hp X14 gets 
commonalized into a dtsi (and it stays compatible to the derived 
device trees, like the Ultrabook G1q). 

The supported features are the same as for the original Omnibook X14:

- Keyboard (no function keys though)
- Display
- PWM brightness control
- Touchpad
- Touchscreen
- PCIe ports (pcie4, pcie6a)
- USB type-c, type-a
- WCN6855 Wifi-6E
- WCN6855 Bluetooth
- ADSP and CDSP
- X1 GPU
- GPIO Keys (Lid switch)
- Audio definition (works via USB and with internal speakers)
