Subject: [PATCH v11 2/6] arm64: dts: mt8183: add capacity-dmips-mhz
Date: Mon, 27 May 2019 17:04:43 +0800	[thread overview]
Message-ID: <1558947887-31084-3-git-send-email-erin.lo@mediatek.com> (raw)
In-Reply-To: <1558947887-31084-1-git-send-email-erin.lo-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

From: "Hsin-Yi, Wang" <hsinyi-F7+t8E8rja9g9hUCZPvPmw@public.gmane.org>

Pinned the frequency to the max and run dhrystone to get the value.
little cpu: 11071 (max freq: 1989000)
big cpu: 15293 (max freq: 1989000)

11071 : 15293 ~= 741 : 1024
