Subject: [PATCH v3] arm64: dts: meson: S922X: extend cpu opp-points
Date: Wed, 22 Apr 2020 19:39:28 -0400	[thread overview]
Message-ID: <20200422233928.GA2816@imac> (raw)

HardKernel supports overclock through the addition to extra opp points
in their official kernel sources for odroid-n2 [1]. Christian tested
on other S922X devices with "no obvious issues". Neil thinks dvfs and
thermal managementis can keep other S922X devices safe.
