From 75800d701782e89eecaf712fa141082b6e36f956 Mon Sep 17 00:00:00 2001 From: Tim Lewis Date: Sun, 26 Apr 2020 12:21:19 -0400 Subject: [PATCH] arm64: dts: meson: S922X: extend cpu opp-points Add extra cpu pop points to allow mild overclock on S922X. The opp points are found in Hardkernel N2 sources [1] and testing shows no obvious issues on other S922X devices. Thermal throttling should keep things in-check if needed.
