Subject: [PATCH v2 2/2] arm64: dts: mnt-reform2: correct i2c3 pad-ctrl
Date: Sat, 18 Dec 2021 19:20:21 +0100 [thread overview]
Message-ID: <20211218182021.235561-2-dev@lynxeye.de> (raw)
In-Reply-To: <20211218182021.235561-1-dev@lynxeye.de>
The slew rate and drive-strength of the i2c3 pads were much too
high. Bring them down to avoid signal quality issues.
