[PATCH] ARM: dts: am43x-epos-evm: Add Missing cpsw-phy-sel for am43x-epos-evm

[George Cherian]

AM437x EPOS evm use external clock for RMII interface.
Enable the same in DT.

Where does this apply on?
With linux-next next-20140506 tag, and this patch applied, I get the
following error.

  LD      kernel/trace/built-in.o
  LD      kernel/built-in.o
build fail, Error:
Error: arch/arm/boot/dts/am43x-epos-evm.dts:219.2-3 label or path,

make[1]: *** Waiting for unfinished jobs....
make: *** [dtbs] Error 2
make: *** Waiting for unfinished jobs....

in the future, it is helpful if you can point out that this is a
regression seen on next-20140603 and the patch needs to be applied on
some specific branch.

for the record:

interestingly, i just re-tested today's tag without the patch
(omap2plus_defconfig):
http://slexy.org/raw/s205sRdFvy

I wonder why the behavior change and what was being fixed here?

Lil old kernel

Linux version 3.15.0-rc4-next-20140506 (nmenon@kahuna) (gcc version 
4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #2 SMP Fri Jun 6 01:47:42 CDT 2014

This kernel should not have the dt entries for phy sel driver.
Thats why it is working.

Uggh.. yeah - 1AM+migraine is not a good combination to try to do
testing. :( Apologies on the noise
