[PATCH v11 2/6] arm64: dts: mt8183: add capacity-dmips-mhz

From: Erin Lo
Date: Mon May 27 2019 - 05:09:00 EST


From: "Hsin-Yi, Wang" <hsinyi@xxxxxxxxxxxx>

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
