Hi Kukjin, Pankaj, Pavel,
I rebased these 3 patchsets (move SROM to drivers, add bank support,
mnove PMU to drivers) on v4.5-rc1 and re-organized the work on usual
arm-soc branches.
Hmmm, maybe not such "usual" because of the dependencies (DTS changes
are needed before removal of code from mach-exynos) this looks a little
bit different. Anyway I put it on a separate branch and tag:
1. samsung-drivers-soc-srom-pmu-4.6
2. samsung-dt-srom-4.6
https://git.kernel.org/cgit/linux/kernel/git/krzk/linux.git/
Everything is also in for-next. The point is that you don't have to do
anything as for now. I'll handle it for v4.6 (hopefully).
Tests on Trats2 passed fine. Now each commit is being tested on mine
Odroid XU3 (http://www.krzk.eu).
Best regards,
Krzysztof

Thanks for hind but I already cleaned it up:

Thank you very much. No, i don't have any questions, i'm glad that my work is
picked up and not lost, i'm just keeping an eye on it
until it goes to stable.
P.S. Not related to these sets directly, just to note... When i was writing
the doc for SROMc bindings, i noticed that we have two
directories for Exynos in Documentation/devicetree/bindings/arm:
1. Documentation/devicetree/bindings/arm/exynos
2. Documentation/devicetree/bindings/arm/Samsung
In (1) we have only a single old file, shouldn't this be cleaned up and
shouldn't this file be moved to (2)?

Let me share the plan/status:
1. Currently Kukjin Kim is out of office (he told me he will be back on
Christmas).
2. I asked arm-soc people to pull my previous pull requests.
3. I applied this patchset to my branch:
next/stuff-late-not-split-per-branch
https://git.kernel.org/cgit/linux/kernel/git/krzk/linux.git/log/?h=next/stuff-late-not-split-per-branch
4. This branch is not pushed to linux-next. I will sort it out if my
previous pull requests get in. I will be out of office for Christmas so
depending on the timing of {arm-soc,Christmas,Kukjin} this may or may
not go into v4.5 (yay...).
5. If it does not get into v4.5, I will rebase it and proceed further
for v4.6.
If you have any questions, please let me know.
Best regards,
Krzysztof

[PATCH v9 0/4] Exynos SROMc configuration and Ethernet support for SMDK5410
This patch extends Exynos SROM controller driver with ability to configure
controller outputs and enables SMSC9115 Ethernet chip on SMDK5410 board,
which is connected via SROMc bank #3.
With this patchset, support for the whole existing SMDK range can be added.
Actually, only bank number is different.
This patchset also depends on Exynos 5410 pinctrl support, introduced by
patches 0003 and 0004 from this set:
[PATCH v4 0/5] ARM: EXYNOS: ODROID-XU DT and LEDs
http://lists.infradead.org/pipermail/linux-arm-kernel/2015-March/330862.html
Pinctrl support is necessary in order to correctly configure
multifunctional pins of the Exynos chip.
v8 => v9:
- Fixed node suffix in ethernet chip DT node (@3,0 instead of @3)
v7 => v8:
- More fixes to documentation
v6 => v7:
- Fixed stupid error in Tacc description in the documentation
v5 => v6:
- Even more improvements to the documentation, fixed some errors and typos.
- Separated adding bus ranges from generic SROMc support
- Some stuff renamed for even better code readability
- Stylistic cleanups in the DTS (everything in alphabetic order, use named
constant name for interrupt config byte)
v4 => v5:
- Some cosmetic changes in the dtsi ("compatible" goes first)
- Use correctly specified ranges for the SROMc node
- Reuse existing properties where possible ("reg" for bank# and
"reg-io-width" for data width)
- Separated page-mode property from timings array
- More improvements to the documentation
v3 => v4:
- Devices are now added as subnodes, with additional properties. This allows
to cleary specify dependency. If configuration fails, error will be reported
and child devices will not be probed.
- These additional properties now have "samsung,srom-XXX" format
- Fixed code style, now better understood.
v2 => v3:
- Fixed up SROMc region size in the device tree
- Reordered patches, documentation goes first now
v1 => v2:
- Fixed some typos and bad labels in device tree
- Improved documentation
