[GIT PULL 0/7] ARM: EXYNOS: Pull request for v4.6

[Krzysztof Kozlowski]

Hi Arnd, Kevin and Olof,

This time pull request directly from me (agreed with Kukjin).


Stuff for v4.6 with some dependencies, split into
separate tags. The need for dependency is explained both
in merge-commit and in description of a tag which is using
the dependency.

The order goes like (but of course dependencies
could be pulled all at once at beginning):
1. tags/samsung-fixes-non-critical-4.6
2. tags/samsung-dt-srom-4.6 (DT changs needed by soc)
3. tags/samsung-drivers-soc-srom-pmu-4.6
4. tags/samsung-soc-4.6
5. tags/samsung-drivers-4.6
6. tags/samsung-dt-4.6
7. tags/samsung-defconfig-4.6 (this will also pull tag from RTC tree)

Please share your comments or just pull.


Kind regards,
Krzysztof

[GIT PULL 1/7] ARM: EXYNOS: Non-critical fixes for v4.6

[Krzysztof Kozlowski]

Hi Arnd, Kevin and Olof,

Few fixes from Arnd.

BTW, I did not apply one fix from his set because I had few comments
(not resolved yet).

Kind regards,
Krzysztof

Hi,

Please use the format:

[GIT PULL 3/7] drivers: soc: EXYNOS drivers for v4.6

Hi Arnd, Kevin and Olof,

This finally moves SROM controller and PMU code to separate
driver under drivers/soc/samsung.

  drivers: soc: Add support for Exynos PMU driver (2016-01-25 10:46:59 +0900)

----------------------------------------------------------------
A set of changes adding new drivers under drivers/soc/samsung:

1. Split code for handling SROM registers out of arm/mach-exynos
   in to separate SROM controller driver under drivers/soc/samsung.
   The driver will save and restore SROM registers during Suspend
   to RAM.

2. Add to this SROM controller driver support for bank configuration
   used by child devices. This allows usage of SMSC9115 Ethernet chip
   on SMDK5410 (Exynos5410) directly connected to SROM controller.

3. Move Exynos PMU driver implementation from arm/mach-exynos
   to the drivers/soc/samsung which will allow re-use of it on ARM64.

Hi,

OMAP has GPMC drivers under drivers/memory. I wonder if SROM should go there
too, since it's a quite similar bus.

Feel free to respin this without SROM now, so we can get the other pieces in
sooner and then revisit the SROM asyncronously. That'll remove the dependencies
on DT as well.

I wish I get this feedback before, when we were discussing the SROM
patches. :/

Indeed this sounds reasonable. On some boards the omap-gpmc is used for
the same purpose: interfacing to smsc,lan9115 (like on SMDK5410).

Okay, I'll rebase all drivers/soc branches and respin the pull request
so PMU driver and other stuff could go in.

BTW, just in case, although PMU stands for "Power Management Unit" I
don't think it should be placed under drivers/power because it is not a
avs/charger/battery/reset driver. Existing power-related drivers are
under driver/soc (bcm, dove, tegra).

Re-work of SROM drivers could be started on top of it.

Best regards,
Krzysztof

Yeah, I apologize -- I usually don't have the bandwidth to follow all
discussions, so I have to catch them when the pull requests come in.

I usually look up the discussions, this time I didn't.

Sounds good, and yes -- those sound appropriate to have under
drivers/soc at least at this time.

(At some point in time we'll have to go through and cleanup
drivers/soc, but we're letting it grow at the moment).

Yes, unfortunately I need your help with that.

I rebased mach-exynos/drivers-soc related patches and pushed it to my
next/soc branch:
https://git.kernel.org/cgit/linux/kernel/git/krzk/linux.git/log/?h=next/soc

There are some changes in commits, mostly for movement of PMU driver
(now it is applied first, before SROMc driver). I also applied some of
the cleanup and maintainer patches from SROMc patchset. DT changes are
already merged.

Overall, could you rebase remaining patches on top of my next/soc and
move SROM driver to drivers/memory? You can also rebase Pavel Fedin's
patches (if you don't I will rebase them).


Last version of applied SROMc patches is here:
https://git.kernel.org/cgit/linux/kernel/git/krzk/linux.git/log/?h=for-v4.6/drivers-soc-exynos-srom-pmu

Hi Arnd, Kevin and Olof,

This pulls previous tags (early DT changes, movement of SROM/PMU
to drivers/soc) and contains other interesting stuff. Description
along with a tag.

  ARM: EXYNOS: Use generic cpufreq driver for Exynos5422/5800 (2016-01-28 19:31:31 +0900)

----------------------------------------------------------------
Samsung Exynos improvements for v4.6:
1. Split out Exynos SROM controller from arm/mach-exynos
   to drivers/soc/samsung. It allows re-using of SROM controller
   driver on ARM64 platform.
   This depends on DT changes.
2. Add banking configuration to Exynos SROM controller.
   This allows usage of SMSC9115 Ethernet chip on SMDK5410 (Exynos5410)
   directly connected to SROM controller.
3. Split out Exynos PMU driver implementation from arm/mach-exynos
   to the drivers/soc/samsung which will allow re-use of it on ARM64.
4. Use generic DT cpufreq driver on Exynos542x/5800.
5. Minor cleanups.

Hi,

This shares most of the contents with the drivers/soc branch (the previous
one).

It's useful to get just the incremental delta instead of the full one, so we
can see what's new in this branch compared to the previous one.

Generating that delta is a little awkward, but you can tell git request-pull
about the different base. If you don't have backmerges since then it should
generate the right diffstat.

Holding off on this branch due to the feedback on the previous one.

Hi,

Merged, but not sure why Viresh acked it instead of applying it.

[GIT PULL 7/7] ARM: EXYNOS: Defconfig changes for v4.6

[Krzysztof Kozlowski]

Hi Arnd, Kevin and Olof,

Defconfig changes, pulling also a tag from RTC tree (merge
of max77802 into max77686 RTC driver).

Kind regards,
Krzysztof


The following changes since commit 92e963f50fc74041b5e9e744c330dca48e04f08d:

  Linux 4.5-rc1 (2016-01-24 13:06:47 -0800)

are available in the git repository at:

  ARM: multi_v7_defconfig: Remove MAX77802 RTC Kconfig symbol (2016-02-05 09:11:32 +0900)

----------------------------------------------------------------
Defconfig (exynos and multi_v7) changes for Exynos based boards for v4.6:
1. exynos defconfig:
   a. Enable NEON and accelerated crypto,
   b. Enable s5p-secss driver (Security SubSystem block for accelerating
      some cryptographic operations),
2. exynos and multi_v7: Remove MAX77802 RTC Kconfig because the driver
   was combined into existing rtc-max77686 driver. This depends on changes
   from RTC tree.

----------------------------------------------------------------
Javier Martinez Canillas (10):
      rtc: max77686: Fix max77686_rtc_read_alarm() return value
      rtc: max77686: Use ARRAY_SIZE() instead of current array length
      rtc: max77686: Use usleep_range() instead of msleep()
      rtc: max77686: Use a driver data struct instead hard-coded values
      rtc: max77686: Add an indirection level to access RTC registers
      rtc: max77686: Add max77802 support
      rtc: max77686: Fix unsupported year message
      rtc: Remove Maxim 77802 driver
      ARM: exynos_defconfig: Remove MAX77802 RTC Kconfig symbol
      ARM: multi_v7_defconfig: Remove MAX77802 RTC Kconfig symbol

Krzysztof Kozlowski (5):
      ARM: exynos_defconfig: Enable NEON, accelerated crypto and cpufreq stats
      ARM: exynos_defconfig: Enable s5p-secss driver
      rtc: max77686: Properly handle regmap_irq_get_virq() error code
      rtc: max77686: Cleanup and reduce dmesg output
      Merge tag 'rtc-max77686-4.6' of git://git.kernel.org/.../abelloni/linux into next/defconfig
