In order for controllers to get PHY in case of non dt boot, the phy
binding information (phy device name) should be added in the platform

I would rather not pass strings around, any other way to handle this ?
Why do you need to pass this string ?

Our old way of binding the controller and the phy using device name
started creating problems after the devices are created using
PLATFORM_DEVID_AUTO. Infact non-dt boot is broken in mainline for
OMAP3 platforms for which I have posted a RFC series
http://www.serverphorums.com/read.php?12,708632 which also uses
strings.
I'm not sure of any other way to deal with this.

have you checked how other frameworks handle it ? Regulator has some
sort of binding in board-files, but I guess it passes the regulator
name?

From whatever I could make of, regulator has 3 ways to get the
regulator one of which is using the binding in board-files (but it
also uses device name which could create the same problem that we are
facing).

1.) from dt data
2.) from _supply_ name
3.) from binding in board file

(referred regulator_dev_lookup() in regulator/core.c)

right, spot on. Which means we don't have a better, more elegant
solution now. Let's go ahead with this.

Ok. So I'll drop RFC and resend this patch series

Thanks
Kishon
