From: Jean-Christophe PLAGNIOL-VILLARD
Date: Wed Nov 21 2012 - 11:01:07 EST


The following adds a helper for matching the linux,stdout-path property
in the chosen node and makes use of it in the i.MX serial and Atmel serial driver.

changes since v4:

- add option support and check stdout-path too

changes since v3:

- move code from separate files to drivers/of/base.c and include/linux/of.h

changes since v2:

- move helper to OF core and make it independent of serial devices

changes since v1:

- move it out of the i.MX serial driver and make it generic for serial
devices.
