Subject: [PATCH v2] ARM: dts: vf610-zii-cfu1: Slow I2C0 down to 100 kHz
Date: Tue, 20 Aug 2019 18:39:36 -0700
Message-ID: <20190821013936.12223-1-andrew.smirnov@gmail.com> (raw)

Fiber-optic modules attached to the bus are only rated to work at
100 kHz, so decrease the bus frequency to accommodate that.
