Subject: arm64: dts: allwinner: a64: Enable A64 timer workaround
|
|
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit?id=55ec26d6a4241363fa94f15377ebd8f1116fbfd7
|
|
|
|
As instability in the architectural timer has been observed on multiple
|
|
devices using this SoC, inluding the Pine64 and the Orange Pi Win,
|
|
enable the workaround in the SoC's device tree.
