he TLL configuration is removed from the UHH driver and implemented as
a seperate platform driver. Now, the UHH driver configures the TLL
through API's exported by the TLL platform driver. The TLL is an
has independent hardware mod structure for in OMAP3 and later chips,
hence an dedicated platform driver is created.

Hi Paul and Tony
since Felipe Balbi is on vacation , Can I get your ack by please?
This is good candidate to v3.5 kernel.
paul,
Just to remind you that, in last ELC Europe , we discussed about the
design of split of UHH and TLL drivers. This series does the same.
regards
keshava

This sentence doesn't parse. Try something simpler like "the TLL is an
separate IP block, independent of the host controller, that basically acts
as a USB PHY". Otherwise it's impossible for other people to understand
what this IP block does.
