change dummy_hcd:MAX_NUM_UDC from 2 to 4 #217

Closed vaishnavachath closed 4 years ago

vaishnavachath commented 5 years ago

The project clickboard support through greybus(https://github.com/vaishnav98/gbsim/wiki/Beagleboard-GSoC-'19:--Clickboard-Support-Under-Greybus) uses dummy_hcd emulated UDC for running the greybus simulator and requires an instance of emulated UDC for each mikrobus port, since the Beaglebone Black Mikrobus Cape has 4 Mikrobus Slots for serving all of the ports through greybus simulator at a time requires 4 emulated dummy_hcd UDC.

Also it would be really helpful if USB_DUMMY_HCD was enabled(as module) in future beagleboard linux builds so that the installation process for Greybus Simulator becomes simpler

thanks @vaishnav98 , i'll merge this.. PS do you want me to start back-porting greybus from mainline, that way we are only really working on one greybus tree?

Yeap, i'll ad usb_dummy_hcd

Regards,

thank you @RobertCNelson , It would be great if you could perform back-porting greybus from mainline as we are planning to work on some modifications to the greybus manifests to support platform data and other additions to greybus.

Do we have greybus on 4.14 now or does it require something newer?

RobertCNelson commented 4 years ago

Opps, this got merged, but didn't close.. I backported GreyBus in our v4.14.x branch from v4.19.81, beyond that was issues..
