TLL block does get used for some cases for non-tll (phy) mode use. Recently there was some low power fixes for non-tll mode in which tll block handling was important. This was specifically in ohci configuration. Anand (in copy) did make some fix which changed ordering of clock enables which were necessary to get usb bus suspend/resume working. With the other ordering you would get an abort when accessing that blocks registers.
