[PATCH 2/2] ARM: dts: qcom: Add support for ASUS ZenWatch 2

Luca Weiss luca at z3ntu.xyz
Sat Feb 26 02:19:39 PST 2022


Add support for this smartwatch, based on Snapdragon 400 SoC.

Currently supported functionality:
* Internal storage
* USB
* Charger
* Power button
* Vibration motor
* Bluetooth
* Wifi

Please note that this patch soft-depends on "Bluetooth: hci_bcm: add
BCM43430A0 & BCM43430A1" which I sent out yesterday.
