We were discussing on whether to have "ti,palmas-usb" or "ti,twl6035-usb" in
compatible value in addition to "ti,palmas-usb-vid". Stephen wanted the old
values ("ti,palmas-usb" or "ti,twl6035-usb") if it has been published in a
release kernel.

Right. Since it's part of 3.11 kernel, I think we should retain the old
compatible values.
