Subject: [PATCH 3/3] arm64: dts: qcom: acer-aspire1: Add embedded controller
Date: Thu, 07 Dec 2023 16:20:16 +0500 [thread overview]
Message-ID: <20231207-aspire1-ec-v1-3-ba9e1c227007@trvn.ru> (raw)
In-Reply-To: <20231207-aspire1-ec-v1-0-ba9e1c227007@trvn.ru>
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.
