Hello,
This patch set switches all Renesas platforms to the new style CMT, MTU2 and
TMU device platform data. All patches have been previously posted as part of
the "[PATCH v3 00/52] Renesas CMT and TMU cleanups" and "[PATCH 00/22] SH
MTU2 DT support" patch series.
This new version just rebases the patches on top of the clockevents branch
that contains the latest driver cleanups, found at
git://git.linaro.org/people/daniel.lezcano/linux.git clockevents/cmt-mtu2-tmu-cleanups
Simon, could you please pull that branch in your tree and apply this series on
top of it ? Furthermore, as I have other pending patches for the driver side,
could you do so in a separate topic branch that Daniel could merge into his
tree ?

With this series applied Bock-W fails to boot both using
Legacy-C and DT-reference, and mackerel fails to boot (using Legacy-C).
In each case the boot hangs and I gave up after waiting two minutes.
I have supplied boot logs below.
I have used the defconfig for each board, tweaking
the result to allow booting DT-reference as appropriate.
I have not tested the SH boards and indeed I have no means to test most of
them. It does seem to me, given my results from testing on the ARM side,
that there is scope for regression on the SH side. I wonder if we can avoid
updating support for legacy boards which we can't verify.

I've debugged the issue on Mackerel, I had "just" used evt2irq instead of
intcs_evt2irq for the TMU resources :-/ I'll resubmit this series with the
problem fixed.
I've also found another issue in the sh_cmt driver that would break bisection
and have submitted a fix for that separately.
I don't have access to a Bock-W board, could you assist me debugging the issue
there ? In particular I'd like to first make sure that the patch that breaks
the kernel is "ARM: shmobile: r8a7778: Switch to new style TMU device". If
that's correct I'll ask you to please test a debugging patch. Another option
would be to give me remote access to a Bock-W board if that's possible.

Not if we want to move forward with the driver and implement DT support I'm
afraid. arch/sh/ is unmaintained and untestable, I thus don't think it
qualifies as a platform that should prevent us moving forward. We should of
course be as careful as possible not to break it, but at the end of the day,
we can't stall ARM development because of SH.

Of course I am happy to help.
I reverted "ARM: shmobile: r8a7778: Switch to new style TMU device" and
the Bock-W once again boots, both using legacy-C and DT-reference.
With regards to debugging, I think that if this becomes a drawn-out process
then it will be easiest for both of us if I give you remote-access. But
as that requires some re-arrangement of things on my side perhaps it would
be easiest if you sent me a debug patch for now.

Fair enough. It is an orphaned architecture after all.

I've attached a debugging patch to this e-mail. Could you please boot the
BockW board with that patch applied before (working) and after (broken)
applying "ARM: shmobile: r8a7778: Switch to new style TMU device" and provide
me with the two boot logs ?

Sure, please see the attached logs.
In both cases I used the bockw_defconfig (and booted using Legacy-C).
In the case of the log bad.txt, the boot hung (I waited for 120sec)
at the point where the log ends.

Indeed.
My bad. *sigh*
Simon, I've sent v5 of 12/15. This should fix the BockW boot issue. I assume
you won't have time to apply the series before leaving for holidays (of
course, if you can, I won't complain :-)). Do you think there will still be
time to get it in v3.16 when you'll return ?
