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,
'phy_sel', not found

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.

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?

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

Tested on next-20140606 - applies clean, builds and works :)
