Hi paul and Felipe
Here is the highlights of the change in the design of USB Host which
we can do after kernel 3.2 release;
1. separate the TLL changes from UHH
2. The TLL is be a new platform driver in ./drivers/mfd
3. the TLL platform driver will export apis for enable/disable clocks
and settings.
3. the UHH drivers uses these APIS of TLL based on the port
configurations from board files
you don't need the TLL clocks to
be on while all the ports are in phy mode.
please let me know your thoughts about it.
regards
