The series comes from my commit in U-boot
d64b9cdcd4 ("fdt: translate address if #size-cells = <0>")
and from the subsequent exchange of emails at the end of which I was
suggested to send the patch to the linux kernel
(https://patchwork.ozlabs.org/project/uboot/patch/1614324949-61314-1-git-send-email-bmeng.cn@gmail.com/).

It's 'ranges' that determines translatable which is missing from the
DT. This should have not had a 0 size either though maybe we could
support that.

I have replied to the email you sent to the u-boot mailing list

Does the DT have to be updated anyways for your spread spectrum support?

The spread spectrum support patch does not need this patch to work. They belong
to two different series.

That's not what I asked. Is the spread spectrum support forcing a DT
update for users? 

Yes, the deltam and modfreq registers must be added to the DPLL clocks. 

If the DT has to be changed anyways (not really
great policy), then you could fix this in the DT at the same time.

I could put the fix to the device tree in that series, although I wouldn't 
create a single patch to fix and add the SSC registers. First the size-cells = <0> 
fix patch and then the SSC patch. 
Do you agree?

Thanks and regards,
Dario
