Subject: [PATCH V3 01/15] dt-bindings: cpufreq: mediatek: Add MediaTek CCI property
Date: Fri, 15 Apr 2022 13:59:02 +0800	[thread overview]
Message-ID: <20220415055916.28350-2-rex-bc.chen@mediatek.com> (raw)
In-Reply-To: <20220415055916.28350-1-rex-bc.chen@mediatek.com>

From: Jia-Wei Chang <jia-wei.chang@mediatek.com>

MediaTek Cache Coherent Interconnect (CCI) uses software devfreq module
to scale the clock frequency and adjust the voltage.
The phandle could be linked between CPU and MediaTek CCI for some
MediaTek SoCs, like MT8183 and MT8186.
Therefore, we add this property in cpufreq-mediatek.txt.
