IMO, this is pointless obfuscation. It just makes it a pain to grep
source around. Why don't you have UDC drivers initialize the 1-bit flags
directly ?

Do you mean something like this? It just makes it a pain to scroll this
source ;)

but it's at least easy to grep. Another option would be the following:

EP_INFO("ep0", USB_EP_CAPS(USB_EP_CAPS_TYPE_CONTROL,
			USB_EP_CAPS_DIR_ALL)),

that also helps grepping.
