Actually it just occurred to me that if something broke
*wait_target_ready(), we'd expect to see intermittent failures
like this,
and this series touches *wait_target_ready(). So it might be
worth taking
a look at that with a magnifying glass to make sure that it's
working.
I think this is probably something else, and most likely more
hideous. The
clock source timers are only enabled once during a boot, and they
are never
idled after that. This error happens almost 5 seconds after the
initial
module enable...?

Actually it just occurred to me that if something broke
*wait_target_ready(), we'd expect to see intermittent failures like this,
and this series touches *wait_target_ready(). So it might be worth
taking
a look at that with a magnifying glass to make sure that it's working.
I think this is probably something else, and most likely more hideous. The
clock source timers are only enabled once during a boot, and they are
never
idled after that. This error happens almost 5 seconds after the initial
module enable...?
I have not seen this and I've had this branch merged in for testing
here for about a week now. I've also merged it into linux-omap master
branch for merging now, let's keep it there and plan on merging it early
for v3.19 merge window unless some issues are found.
Hmm here seems to be a link to similar issues from 2011:

Looks like the issue can be potentially reproduced with:

running here on am335x and am437x. On that same post, on person

Hi,
This set contains PRCM related cleanups meant for 3.18 merge window.
These are based on top of 3.17-rc1 + the PRM set from Nishanth Menon
(http://article.gmane.org/gmane.linux.ports.arm.kernel/350305.) Nishanth's
set is used as basis to avoid merge issues.
Purpose of this work is to eventually convert the PRCM code into a
separate driver, but this is done in incremental parts as the amount
of changes is substantial. Expected conclusion of this work is 3.19
if everything goes fine.
This part of the work mostly moves some of the SoC specific PRCM driver
calls under generic version of the same, and adds SoC-ops to support
these on the driver level.
Working branch posted here:
tree: https://github.com/t-kristo/linux-pm.git
branch: for-v3.18/prcm-cleanup
Hi,
I pushed v2 of this set as 'for-v3.18/prcm-cleanup-v2' to my tree. Basically
to address the below comments, and additionally I changed a few public cm_*
api names to omap_cm_* + add the tested-by/acked-by statuses. Tony/Paul, do
you want me to repost the series, or are you ok with a local diff / pull
only?
If the changes were minor, at least I'm fine without reposting.
But let's wait to hear from Paul in case he has further comments.
Regards,
Tony
Paul, any comments on this series?
Patches 1, 3, 5, 8, 10, 13, 17, 18, 20, 21, 22, 23, 24 are:
Acked-by: Paul Walmsley p...@pwsan.com
Thanks, added acks to v2 patches.
Here are some specific comments on a few other patches:
Regarding patch 7: The kerneldoc-nano function comments are good, but
should begin with /** rather than /*. When that's fixed, it can be
considered acked by me.
Yea, this was a typo, thanks for noticing.
Regarding patches 14, 15, 16: Non-static prm_* functions really should
start with omap*_ to avoid potential naming conflicts with other drivers
when these are moved to drivers/. (Obviously the same would apply for any
CM function names in other, future patches.) When that's fixed, it can be
considered acked by me.
Ok, changed. Additionally I changed some cm_* prototypes in patches #6, #7
and #9 to be of form omap_cm_*.
Regarding patch 25: What are I/O wakeup gaes -- gates? When that's
fixed, an acked-by for me can be added.
Yes, gates. Fixed.
Regarding patch 26: It seems wise to ensure that omap_prm_reset_system()
ends with a 'while(1) { cpu_relax(); }' or something similar, to ensure
that execution flow does not proceed past that point. At that point, it
should be possible to remove the while(1) {}s from omap44xx_restart(),
omap2xxx_restart(), etc. When that's fixed, an acked-by for me can be
added.
Ok, changed this also. Added the while(1) cpu_relax(); part to the public
API, and removed the loops from everywhere else.
...
And some general comments: none of which should probably block this
series, but seemed worth noting:
Regarding patches 6 and 19: Tero, could you please share the DT node data
that you're planning to submit for the PRM, CM1, and CM2 on the OMAP4*
platforms? According to the TRM, these are separate IP blocks, with
separate OCP header register areas. So these should probably have
separate DT nodes, regs, etc. if the DTS files are to match the hardware.
The planned DTS data may impact the way these patches are written, at
least, if more patches are to be avoided later.
We already have the nodes for these. Check out omap4.dtsi for example, we
have nodes for prm/cm1/cm2/scrm there already. These were already defined
when the clock DT data was introduced, and I don't foresee any changes to
the nodes as of now. The nodes only contain register space info as of now,
and Nishanth is adding the interrupt property for PRM interrupt purposes,
but rest of the features are probably going to be hardcoded within the PRCM
drivers themselves.
If you are interested, feel free to look at for-3.19/prcm-cleanup branch in
my git tree, this contains the remaining patches I have for PRCM cleanup
after this set available as of now.
-Tero
As far as patches 2, 4, 9, 11, and 12 go, I'll let those go without
comment.
