Should have been picked up by SCSI/UFS maintainers, but it 
hasn't, so I applied it.

And it now triggers schema warnings, because sc7180-ufshc has 7 clocks
and 1 reg entries.

And now dropped... Perhaps the dts changes should be too.

Maybe QCom maintainers should require a report of dtbs_check on new
boards. My comparisons of Linus vs. next warnings often show an
increase in QCom warnings. Like right now:

linus: arch/arm64/boot/dts/qcom:1990:265
next: arch/arm64/boot/dts/qcom:1610:298

First number is total warnings. Second number is unique warnings
(stripping dtb name). Some of this is just mismatch between schemas
and dts changes showing up in next, but it doesn't tend to go to 0 as
the merge window approaches. I've seen this several cycles. All the
data is available from my CI jobs, and I regularly look at the diff
with this:

$ less ~/bin/gl-diff-dtb-warnings
#!/bin/sh

[ -z "$1" ] && { echo "Missing arch!"; exit 1; }

arch="$1"

job="job-dtbs-check"
logfile="platform-warnings.log"

# url <branch> <arch>
url() {
        local branch="$1"
        local arch="$2"
        echo "https://gitlab.com/robherring/linux-dt/-/jobs/artifacts/${branch}/raw/${logfile}?job=${job}%3A+%5B${arch}%5D"

}

curl -Ls -o orig.log $(url linus ${arch})
curl -Ls -o next.log $(url next ${arch})
meld orig.log next.log

I was tracking new dtbs_check warnings on Qualcomm for selected
subsystems and for selected boards, but that grew faster than I was able
to fix it so I gave up...

After all these months and all these review feedbacks many people still
do not test their DTS with dtbs_check, so maybe the solution is to start
dropping people's patches? Detect new warnings and drop the patch from
Qualcomm tree?

That's useful, thanks!

Best regards,

Still a bunch of warnings in next. This binding should be resubmitted
with fixes or the dts changes dropped.
