After looking in to what's going on here more, this should be:
	select EVENT if OF_LIVE

And is a standalone bug fix. The event in question here lives in
arch/arm/mach-snapdragon/of_fixup.c and is for both USB things and
OP-TEE things (so USB_DWC3_GENERIC is wrong), but desired even if U-Boot
doesn't use USB as the linux kernel will consume this device tree, if I
recall correctly. But next, this only fires on EVT_OF_LIVE_BUILT and not
one of EVT_DM_POST_INIT_[FR] which is what DM_EVENT gates.

All of that said, what exactly is the failure to build you saw in your
series, without the above? I do worry there's something else further
going on here. Thanks!
