[usb] clk of the SIE

[ZhiPLiu <zpingl@263.net>]

Hi all,

 Is the clk of SIE the output clk of  PHY chip? and  but on the
UTMI specification(version 1.05) the output clk is 48Mhz in fs only 
operation,the data rates is 12M.why the output clk is 48Mhz. "A 'fs ony' 
implementation of the utm would provide 32 clk cycles per byte time"  is
in the page 22 of the utmi specification,but "the clocking of a hs/fs utm 
in fs only and ls only implementations,except that for fs only and ls only 
implementations there are only 8 clk cycles per byte time"  is on the  
page 25. do they conflict.
