[PATCH 3/3] arm64: dts: qcom: glymur-zenbook-a16: Add Embedded Controller

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

The Glymur-based Zenbook A16 features an Embedded Controller running
custom ASUS firmware (which is loosely based on the reference Qualcomm
Hamoa EC one with a lot of modifications). It provides keyboard
backlight control, additional temperature sensor readouts, fan speed
monitoring and a number of miscellaneous functions.

Describe it.
