This patches causes a regression on a imx51-babbage running 4.18-rc1:
I get a kernel hang.

If I revert it on top of 4.18-rc1, then it boots fine and USB host is
functional.

I understand this patch fixes a kernel hang for you, so which commit
is responsible for the hang you observe?

I never assumed it was a regression and that USB worked on RDU1 board
before, so I never tried to see if this was a regression. I can only
tell you that it hangs as soon as any PORTSC registers are accessed.

Hang at register access usually means that module that owns the register
is not clocked.
