Subject: [RFC PATCH-for-6.1 v2 6/6] hw/mips/loongson3_virt: Raise CPU clock to 2 GHz
Date: Fri,  9 Apr 2021 11:36:23 +0200	[thread overview]
Message-ID: <20210409093623.2402750-7-f4bug@amsat.org> (raw)
In-Reply-To: <20210409093623.2402750-1-f4bug@amsat.org>

Commit cd3a53b727d ("clock: Add clock_ns_to_ticks() function")
removed the limitation of using clock with a frequency of 1 GHz
or more.

The previous commit converted the MIPS CP0 timer to use this
new clock_ns_to_ticks() function. We can now use a clock of
2 GHz with the Loongson3 virt board.
