Subject: [PATCH v2 2/4] cpufreq: dt-bindings: add bindings for mtk-cpufreq driver
Date: Wed, 4 Mar 2015 16:49:14 +0800 [thread overview]
Message-ID: <1425458956-20665-3-git-send-email-pi-cheng.chen@linaro.org> (raw)
In-Reply-To: <1425458956-20665-1-git-send-email-pi-cheng.chen@linaro.org>
Add dt-binding for mtk-cpufreq driver so that the driver could get SoC specific
information (intermediate_clk for now) from device tree.

+Mediatek cpufreq driver
+-------------------
+
+Mediatek SoC cpufreq driver for CPU frequency scaling.
+
+Required properties:
+- compatible: "mediatek,mtk-cpufreq"
+- intermediate_clk: The intermediate clock source which CPUs will switch to
+during CPU frequency transition.
+
+Examples:
+--------
+ mtk-cpufreq {
+ compatible = "mediatek,mtk-cpufreq";
+ intermediate_clk = <&apmixedsys APMIXED_MAINPLL>;
+ };
