Subject: ARM: dts: vf610-zii-cfu1: Slow I2C0 down to 100 kHz
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=801592402c392acb0f2ead971d1e8f0e0565b60e;p=linux.git

ARM: dts: vf610-zii-cfu1: Slow I2C0 down to 100 kHz

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