[PATCH 0/2] s3c RTC fix for Exynos Chromebooks

[PATCH 0/2] s3c RTC fix for Exynos Chromebooks

[Javier Martinez Canillas]

Hello Kukjin,

commit 546b117fdf17 ("rtc: s3c: add support for RTC of Exynos3250 SoC")
added an "rtc_src" DT property for the Samsung's S3C Real Time Clock
controller that specifies the 32.768 kHz clock that uses the RTC as
its source clock but this breaks the s3c RTC on Exynos Chromebooks
because the rtc device node does not define the "rtc_src" clock.

It was working before only because the source clock was not disabled
by the kernel since the CCF didn't know about it. But once the clock
is known, the CCF disables the clock and does not work so define the
"rtc_src" clock to make the s3c-rtc driver obtain it and kept enabled.

This series makes the s3c RTC to claim its source clock on the Snow
and Peach boards but other Samsung boards will have the same issue.

The following patches are meant to be for the 3.18 rc cycle once
3.18-rc1 is released.

Wait, seriously?  Snow is still using the "rtc@101E0000" syntax?
Whatever happened to the series that Andreas worked so hard on,
including <https://patchwork.kernel.org/patch/4664801/>?

Kukjin: Andreas's patch series was Reviewed long ago I think and by
now I'd imagine it's got some conflicts due to it not having been
applied in a timely fashion.  Perhaps you could fix it up for Andreas
(since he's already rebased it several times) and land it?

If I had to guess, outstanding from Andreas's series (patchwork IDs listed):

4751131 New          [v7] ARM: dts: Prepare node labels for exynos5250

In any case, there's nothing wrong with Javier's patch other than the
fact that it will eventually need to get merged with Andreas's, so:

Wait, seriously?  Snow is still using the "rtc at 101E0000" syntax?

Yes, Kukjin told me not to resend anything, and I haven't heard back
from him since his Kernel Summit trip.

Today I also had time to review the rebased patches from Andreas and found
two issues introduced during the merge conflict resolution:

1) The spi_1 dev node on exynos5250-smdk5250.dts now uses the old "cs-gpio" 
   DT property under the controller-data instead of the standard "cs-gpios"
   under the SPI parent. IOW, is a regression of the bug fixed in commit
   e138d43 ("ARM: dts: fix the chip select gpios definition in the SPI nodes").

2) The display-timings child node of the dp-controller was removed in commit
   a98c3c2 ("ARM: dts: update display related nodes for exynos5250-snow") but
   was introduced again in the Snow DTS during the merge.

I'll post a series that fixes both issues with the following patches:

Javier Martinez Canillas (2):
      ARM: dts: Fix chip select GPIO on smdk5250
      ARM: dts: Remove display timings node from exynos5250-snow

I see that you already send a pull request to arm-soc maintainers so probably
these will be part of the fixes during the 3.18 rc cycle.

Best regards,
Javier

Great. It would be awesome also if you can also pick Sjoerd's USB series [0]
which solves an issue with USB on certain configurations.

I looked at your for-next branch but I didn't see those patches there.

Great. It would be awesome also if you can also pick Sjoerd's USB series [0]
which solves an issue with USB on certain configurations.

I looked at your for-next branch but I didn't see those patches there.

Andreas, I completely forgot about your series when writing this patch even
though I've on my TO-DO to sync the downstream and upstream Snow DTS once your
patches land. Sorry about that.
