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,

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:
last working next tag:
https://github.com/nmenon/kernel-test-logs/blob/next-20140602/omap2plus_defconfig/am43xx-epos.txt
first broken next tag:
https://github.com/nmenon/kernel-test-logs/blob/next-20140603/omap2plus_defconfig/am43xx-epos.txt
interestingly, i just re-tested today's tag without the patch
(omap2plus_defconfig):

Lil old kernel
from the above link.
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
I wonder why the behavior change and what was being fixed here?
This kernel should not have the dt entries for phy sel driver.
Thats why it is working.
