Subject: [PATCH 2/2] dt-bindings: i2c: aspeed: add base-clock-divisor property
Date: Wed, 19 Jun 2019 13:50:18 -0700	[thread overview]
Message-ID: <20190619205018.4177192-1-taoren@fb.com> (raw)

"base-clock-divisor" allows people to customize ASPEED I2C Controller's
Base Clock, which in turn adjusts all other I2C AC timing settings.
