[PATCH v1 0/2] external ulpi vbus control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A customer sent me a patch adding a dt property to enable external vbus
control as their phy didn't support it*. I was surprised to see that none
of the other musb drivers made any use of this, but there is handling
in the musb core for it - made me feel like I was missing something as
to why it was not used by other drivers.

I've vendor prefixed the property for now, but I figure there may well
be a bunch of other potential users since this isn't just an musb thing,
given that there's a snps,ulpi-ext-vbus-drv used by an xHCI IP.

This is my third attempt to send these patches. I cannot find them on
lore from either of my previous attempts, so I'm gonna treat this as
v1. I think must've tried to send it from my kernel.org account from
Microchip's corp network and that failed. Either way, apologies if this
is #3 you've got from me..

* they didn't want to be identified, but said it was okay to post.
