The timer is initialized right after musb is probed. There is actually no need to have this timer running because _nothing_ will happen until we have the gadget loaded. Also we need this timer only if we run in OTG mode _and_ we need it also after the gadget has been replaced with another one. I've been looking at am35x.c, da8xx.c, omap2430.c, tusb6010.c. da8xx seem to have the same problem as dsps and doing mostly the same thing. tusb6010 seem to do something different and do some actual "idle / power saving" work so I am not too comfortable to remove musb_platform_try_idle() from musb_gadget_setup(). Therefore this patch does not start the timer if there is no gadget active (which is at musb_gadget_setup() at time). In order to have the timer active after the gadget is loaded it will be triggered from dsps_musb_enable().
