Subject: [PATCH v3 3/4] arm64: dts: apple: t8103: Add i2c nodes
Date: Mon, 22 Nov 2021 23:58:06 +0100 [thread overview]
Message-ID: <20211122225807.8105-4-j@jannau.net> (raw)
In-Reply-To: <20211122225807.8105-1-j@jannau.net>
Apple M1 has at least 5 i2c controllers. i2c0, i2c1 and i2c3 are used
on all M1 Mac devices. The 2020 Mac Mini uses i2c2 and the 13-inch
MacBook Pro uses i2c2 and i2c4.
