That's not a correct frequency. You silence some error by introducing
incorrect properties. That's wrong.
A clock-frequency of 0 seems valid for a clock that is disabled or not
used on a particular board. I chose this approach because it already has
widespread usage in the kernel:
grep 'clock-frequency = <0>' arch/arm64/boot/dts/*/*.dtsi | wc -l
198
Don't fix the warnings just to silence them, while keeping actual errors
still in the code.
I actually want to fix the existing warnings, but it seems appropriate to
only address the existing warnings that are related to this patch set of
adding PCIe Root Port support to the Agilex family of chips. This patch
set requires touching the file, socfpga_agilex.dtsi; so I fixed the
warnings I thought were in this file. I believe the other warnings need to
be fixed by converting text binding descriptions to yaml or by touching
files unrelated to this patch set.
Setting the value of the status property to "disabled" also silences the
particular fixed-clock, but I didn't see any other usage by a fixed-clock.
What do suggest is the best way to handle this warning?
Best regards,
Krzysztof
