I am working with an SOC family where I have Synopsys UDC on one of the
SOC, while Synopsys OTG on other as USB device. I have a single
defconfig for all the SOCs of this family.
In the current kernel configuration , it is not possible to select
more than one USB peripheral controller under USB gadget support.
So one can either select Syn UDC or Syn OTG. Both of them can not
be selected and compiled together. So, a unique defconfig is not
possible for all the SOCs of same family.
What do you suggest to handle this situation.
It is a known problem and some work is being done to resolve it. If
I remember correctly, it should be possible to do in 3.1 after a bunch
of patches implementing UDC class and some other stuff are merged into
the mainline (I don't think they are present in 3.0).
You might want to check patches from Felipe and Sebastian sent in the
past quarter.
