Subject: [PATCH 3/3] arm64: dts: nitrogen8-som: correct i2c1 pad-ctrl
Date: Sun, 12 Dec 2021 14:49:12 +0100 [thread overview]
Message-ID: <20211212134912.1988208-3-dev@lynxeye.de> (raw)
In-Reply-To: <20211212134912.1988208-1-dev@lynxeye.de>
The slew rate and drive-strength of the i2c1 pads were much too
high. Bring them down to avoid signal quality issues.
Signed-off-by: Lucas Stach <dev@lynxeye.de>
