Subject: [PATCH 337/478] FROMGIT: 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.
