Subject: [RFT PATCH] mmc: pwrseq: Use highest priority for eMMC restart
handler
The pwrseq_emmc driver does a eMMC card reset before a system reboot to
allow broken or limited ROM boot-loaders, that don't have an eMMC reset
logic, to be able to read the second stage from the eMMC.
But this has to be called before a system reboot handler and while most
of them use the priority 128, there are other restart handlers (such as
the syscon-reboot one) that use a higher priority. So, use the highest
priority to make sure that the eMMC hw is reset before a system reboot.

Looks good.

+Cc Ulf,
Javier,
First of all, thanks Javier for digging into the issue. Actually I have
Odroid U3 but because of user-space limitations (which I need for other
work) I cannot test all of mainline patches there.
Thanks, should I post it as a proper patch or are adding it to your
series?
Suggest you to post as a patch collecting {Tested, Reviewed}-by (easy
for maintainers to pickup ) and probably CCing Ulf for his feedback.
I think the latter is more reasonable so with an ack from Ulf,
all patches can go through the linux-samsung tree.
yes, that is reasonable, as I said, let Krzysztof and Ulf take a call here.
Javier, Alim, Ulf,
I am not grabbing any more patches for v4.4 because I doubt that they
could be merged to arm-soc for this cycle. My last pull requests for
v4.4 is still pending...
This means that I plan to pick up these series for v4.5, after closing
v4.4 merge window (unless Kukjin picks it also). Because of that, we
have plenty of time, so my idea is:
1. Wait for some comments from Ulf on Javier's fix.
2. If the fix goes into v4.4, then problem solved.
3. If not and it get acked, then it can go with this set.
4. If not and it get applied by Ulf for v4.5, then a tag from him would
be a nice way to solve dependency.
Either way we don't have to hurry, I think.
Is It the right time to get this series in?
Thanks!!
I started applying it but stopped at #5. It should be squashed with #6
to get rid of (not important) conflict between syscon reboot and
existing Exynos restart handler:
syscon-poweroff syscon-poweroff: pm_power_off already claimed c001e52c
exynos_power_off
syscon-poweroff: probe of syscon-poweroff failed with error -16
The conflict is not really an issue because of ordering of init calls
the Exynos will register itself before syscon. Nevertheless splitting
the patches does not really make sense... so please merge #5 with #6.
Hmm...nice catch..will send v3 shortly after merging patch #5 and #6.
Best regards,
Krzysztof
