Subject: [PATCH 10/11] arm64: dts: qcom: acer-aspire1: Add embedded controller
|
|
|
|
The laptop contains an embedded controller that provides a set of
|
|
features:
|
|
|
|
- Battery and charger monitoring
|
|
- USB Type-C DP alt mode HPD monitoring
|
|
- Lid status detection
|
|
- Small amount of keyboard configuration*
|
|
|
|
[*] The keyboard is handled by the same EC but it has a dedicated i2c
|
|
bus and is already enabled. This port only provides fn key behavior
|
|
configuration.
|
|
|
|
Add the EC to the device tree and describe the relationship between the
|
|
EC-managed type-c port and the SoC DisplayPort.
