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

[Krzysztof Kozlowski]

Hi,

This patchset adds 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).

Best regards,
Krzysztof

Any reason for not applying compatible strings for the other devices?

Partially yes because I do not want to add them for devices which I
cannot test (s5m8761, s5m8763) but you're right that there are no
obstacles for s2mps11, s5m8767 and s2mps14.

I'll fix this in next version.

Just a trivial thing, Kconfig description can also be updated.
