[PATCH v3 0/3] clk: s2mps11: Add support for S2MPS14 clocks

[PATCH v3 0/3] clk: s2mps11: Add support for S2MPS14 clocks

[Krzysztof Kozlowski]

Hi,

This is third version of patchset adding support for the S2MPS14
device to the s2mps11 clock driver.


The patchset *depends on*:
==========================
1. Work done by Tushar Behera:
   [PATCH V2 0/2] Add support for clocks in S5M8767
   http://thread.gmane.org/gmane.linux.kernel.samsung-soc/27264
2. Support for S2MPS14 in main sec-core MFD driver (already in linux-next
   and Lee's tree).

Changes since v2:
=================
1. Patch 2/3: Remove MFD cells of_compatible which aren't used by child
   drivers and are not documented.
2. Added Tomasz's Review-by.

Changes since v1:
=================
1. Patch 1/3: Update driver description in Kconfig.
2. Patch 2/3: Add of_compatible to all MFD cells.
3. Add Yadwinder's Review-by.

Best regards,
Krzysztof

This does not apply cleanly to to clk tree trip, nor does it compile
after manually merging due to changes introducing
linux/mfd/samsung/s2mps14.h.

The changes look OK to me so maybe Lee can take it with my Ack?

I took those patches in yesterday. So we have three options:

1) MFD tree can pull a stable commit from the clk tree. I'm happy to
make a topic branch for this. Then these patches can be applied.

2) clk tree can pull a stable commit from the mfd tree if the mfd folks
can provide one.

3) Wait until after the merge window to apply this one to the clk tree.
I don't currently plan to send 2 PRs during the merge window, so this
could either go in 3.16 or maybe into 3.15 if a split PR is sent.

Regards,
Mike

Dear Lee,

How do you wish to proceed? The patchset depends on changes in sec-core
MFD driver.

The MFD tree is betting pretty complicated with sec-core stuff at the
minuite. Can I vote for option 3?

Thanks! One minor thing - I see that Tomasz' Review-by got lost when the
patch was applied to your tree:

Thanks for the prod, but I do have it applied locally. I'll push the
branch later today.
