Subject: [PATCH v10 6/8] dt-bindings: i2c: rk3x: add support for rk3399
Date: Mon, 16 May 2016 22:04:12 +0800 [thread overview]

In-Reply-To: <1463407063-41218-1-git-send-email-david.wu@rock-chips.com>
The bus clock and function clock are separated at rk3399,
and others use one clock as the bus clock and function clock.
