Subject: [PATCH v4 2/2] dt-bindings: aspeed-i2c: add properties for setting i2c clock duty cycle
Date:   Fri, 10 Jun 2022 13:47:22 +0800
Message-Id: <20220610054722.32229-3-potin.lai.pt@gmail.com>

References: <20220610054722.32229-1-potin.lai.pt@gmail.com>
Precedence: bulk

Introduce a new property for setting a minimum duty cycle for clock high.

* i2c-clk-high-min-percent: a minimum percentage of clock high
