Just trying to understand things here.
Is the device name we are using here the platform device name (pdev->name) ?
If i am not wrong then for devices added through device tree
the device name would actually include the device address in the string,
wouldn't that make things somewhat weird, since we will have to add
such bindings
using this address string.
one more doubt please :)
is it possible to bind phy in the controllers' driver somehow ?
