[PATCH 5.13 176/266] MIPS: CI20: Reduce clocksource to 750 kHz.
From: Greg Kroah-Hartman
Date: Thu Jul 15 2021 - 15:38:39 EST
From: 周琰杰 (Zhou Yanjie) <zhouyanjie@xxxxxxxxxxxxxx>
[ Upstream commit 23c64447b3538a6f34cb38aae3bc19dc1ec53436 ]
The original clock (3 MHz) is too fast for the clocksource,
there will be a chance that the system may get stuck.
