Subject: [PATCH v2 5/9] arm64: dts: apple: s800-0-3: Add I2C nodes
Date: Tue, 10 Jun 2025 21:45:24 +0800	[thread overview]
Message-ID: <20250610-i2c-no-t2-v2-5-a5a71080fba9@gmail.com> (raw)
In-Reply-To: <20250610-i2c-no-t2-v2-0-a5a71080fba9@gmail.com>

Add I2C nodes for Apple A9 SoC.

There is actually an i2c3 on this SoC but the SCL and SDA lines
appears to be not connected and no peripherals are expected to be
connected to it, so there is no node for it.
