Yes, you are right. But i was hesitant to add a multi-level header
file include in the phy driver
which uses it.
Does it makes sense to move this ulpi_phy.h to include/linux/phy ?

This serves including all the directory paths in the 'make' for
driver/phy/Makefile.
Otherwise each directory will have to be built as per particular platform
And, not all drivers of a vendor are built for one-kind of platform,
for example, Samsung uses ARCH_EXYNOS, as well as ARCH_S5PV210
Similarly, Broadcom phy drivers are based on multiple platforms, and so
does Marvell's.
Please suggest a concise way to include the vendor directories in the build path
in drivers/phy/Makefile.

I Think this applies to ulpi_phy only at this moment, which we can resolve
by moving that to include/linux path.
