Subject: [PATCH 3/3] arm64: dts: fsl: ls1046a: Add mul-value property of the i2c controller nodes
Date:   Tue, 30 Apr 2019 12:32:42 +0800
Message-Id: <20190430043242.29687-3-chuanhua.han@nxp.com>
In-Reply-To: <20190430043242.29687-1-chuanhua.han@nxp.com>
References: <20190430043242.29687-1-chuanhua.han@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

According to LS1046A Reference Manual, for the i2c controller, you have
up to three MUL options available for all divider values. Therefore, we
need to determine which MUL to use in the device tree for driver use.

The "mul-value" property provides which mul is used in our driver.
