Hi Zhou, Le sam., juin 26 2021 at 14:18:40 +0800, 周琰杰 (Zhou Yanjie) [off-list ref] a écrit :
The original clock (3 MHz) is too fast for the clocksource, there will be a chance that the system may get stuck. Reported-by: Nikolaus Schaller <redacted> Tested-by: Nikolaus Schaller <redacted> # on CI20 Signed-off-by: 周琰杰 (Zhou Yanjie) <redacted>
Acked-by: Paul Cercueil <paul@crapouillou.net> Cheers, -Paul
