Pull i2c-embedded changes from Wolfram Sang:
"Major changes:
- lots of devicetree additions for existing drivers. I tried hard to
make sure the bindings are proper. In more complicated cases, I
requested acks from people having more experience with them than
me. That took a bit of extra time and also some time went into
discussions with developers about what bindings are and what not.
I have the feeling that the workflow with bindings should be
improved to scale better. I will spend some more thought on
this...
- i2c-muxes are succesfully used meanwhile, so we dropped
EXPERIMENTAL for them and renamed the drivers to a standard pattern
to match the rest of the subsystem. They can also be used with
devicetree now.
- ixp2000 was removed since the whole platform goes away.
- cleanups (strlcpy instead of strcpy, NULL instead of 0)
- The rest is typical driver fixes I assume.
All patches have been in linux-next at least since v3.4-rc6."
Fixed up trivial conflict in arch/arm/mach-lpc32xx/common.c due to the
same patch already having come in through the arm/soc trees, with
additional patches on top of it.
