Subject: [PATCH] [RESEND] arm64: dts: mt8173: Add dynamic power node.
Date: Fri, 22 Nov 2019 17:06:10 +0800 [thread overview]
Message-ID: <20191122090610.17015-1-michael.kao@mediatek.com> (raw)
From: "michael.kao" <michael.kao@mediatek.com>
This device node is for calculating dynamic power in mW.
Since mt8173 has two clusters, there are two dynamic power
coefficient as well.
