Subject: [PATCH 2/2] arm64: dts: allwinner: a100: Update I2C controller fallback
Date: Sat, 2 Jul 2022 00:25:43 -0500 [thread overview]
Message-ID: <20220702052544.31443-2-samuel@sholland.org> (raw)
In-Reply-To: <20220702052544.31443-1-samuel@sholland.org>
The I2C controllers in the A100 SoC are newer-generation hardware
which includes an offload engine. Signify that by including the
allwinner,sun8i-v536-i2c fallback compatible, as V536 is the first
SoC with this generation of I2C controller.
