Commit 1b1ccee1e821 "mfd: s2mps11: Fix build after regmap field rename
in sec-core.c" is also touching this file, which is in Mark's tree
right now. If I rebase
this patch on top clk-next, I am getting conflicts when I merge that
with linux-next.
Let me know how you want to handle this.

I am attaching the rebased patches for your reference.
If you want, I will send them again through git-send-email.

Patch

Subject: [PATCH 2/4] clk: clk-s2mps11: Add support for clocks in S5M8767 MFD

Since clock operation within S2MPS11 and S5M8767 are similar, we can
support both the devices within a single driver.
