Subject: [PATCH v2 0/3] arm64: dts: qcom: x1-asus-zenbook-a14: LCD, WiFi
 for X1E support

Round of improvements for Asus Zenbook A14, two changes:
1. Support LCD option on X1 (UX3407QA) variant. Until now, 'edp-panel'
   was used for both X1/X1E models, for both OLED panels. The lower end
   model also comes with IPS, which unfortunately needs PWM brightness
   controls. Follow example of Lenovo t14s - create a dedicated DT with
   dedicated 'compatible'. To maintain backward compatibility, do not
   rename current devicetree nor the 'model'.

   As this results in 3 DTs for 3 variants of the laptop, change
   OLED variants from 'edp-panel' to respective drivers (it appears both
   panels happily work both in old and new setup). Compatible for the
   panels were added to linux-next some weeks ago.

2. Add WiFi nodes for X1E (UX3407RA) variant. Almost identical to
   UX3407QA but uses ath12k instead of ath11k. Was not addded during
   initial bring-up due to lack of hardware to verify WiFi's operation.
