Hello,
I am currently implementing USB Host and client support for Freescale Vybrid
platform in u-boot. I managed to get the host implementation working.
For the host side, usb start calls usb_init(), which in turns call,
usb_lowlevel_init(), from there into the ehic_hcd_init() of my implementation.
So, setting up the necessary clocks and plls for USB in my implementation and
then setting up the usb_ehci, ehci_hccr and echi_hcor structures was all. The
flow and setup required i was able to trace.
The USB client part is not clear to me. I was thinking i can use the ci_udc
driver somehow to implement the client part. How can i use the ci_udc driver to
implement client functionality?. From what i could see, the
usb_gadget_driver_register() is suppose to be the first call. But, i couldn't
trace from where this gets called or the flow and setup is suppose to be. OR Is
a separate client driver required and nothing generic can be used akin to how
it could be done for host?
Sorry if i am asking this question in the wrong place. I couldn't find anyone
in the u-boot IRC channel nor find something similar to the kernel-newbies
mailing list.
Hope i am asking the right questions. Sorry if this mail ends up two times in
this list, i mistakenly tried sending it from the mail ID not registered with
this mailing list.
Thanks & Regards,
Sanchayan Maity.
