FYI... in order to avoid cross-tree dependencies going upstream, I split
this series up into two seprate series, and just posted them.  One for
just clocks for Paul[1]:

   [PATCH 0/3] ARM: OMAP3: clock: cleanup AM35xx clock flags

and another for converting most of the users of cpu_is_omap35*[2]:

   [PATCH 0/2] ARM: OMAP3: cleanup AM35xx SoC detection

Once these are merged, I have one more patch[3] (which depends on both of
the above branches) that will remove all the now unused cpu_is_omap35x*
defintions and the last remaining user in the clock code.

Subject: [PATCH] ARM: OMAP: SoC detection: remove unused cpu_is macros

Remove multiple unused cpu_is_omap35xx macros.

In particular, the cpu_is_omap35* macros for 3503, 3515, 3525 are removed
because they are using omap_has_* feature checks and we want to
remove specific feature detection from SoC family detection.

There are no longer any cpu_is_* checks that depend on specific IP
detection.
