Hi all,
I have a doubt in RWE and RWC bits of OHCI control register.
According to OHCI specification RWC bit is to indicate whether the
controller supports remote wakeup or not and this bit is set by the
system firmware at the time of POST. But this bit is set in
ohci_bus_resume depending on hcd->can_wakeup flag. But I don't find
where this can_wakeup flag is initialised.
According to OHCI specification if RWE bit is set and RD bit of
interrupt register is set then only a remote wakeup is signaled to the
host system. Does this mean that if both the bits are set then the
system can resume by remote wakeup?
Or if I put it alternativly, if my bus is suspended selectively and RWE
bit is not set then does RD interrupt can wakeup the bus ?
Please suggest.
Thanks,
Rasmit.
