Subject: [v2] arm64: dts: meson: odroid-n2: extend cpu opp-points
Date: Sat, 18 Apr 2020 17:42:23 -0400	[thread overview]
Message-ID: <20200418214223.GA4484@imac> (raw)

Odroid N2 has a large heatsink and HardKernel supports overclock
through the addition to extra opp points in their official kernel
sources [1]. Add these to the N2 dts only, as other S922X devices
may not have suitable heatsinks.
