Thank you for testing this out on a different platform !
I had a look at how things are done in the Freescale fork of the kernel
(5.4.24_2.1.0) and I noticed that this kernel has almost the same
behaviour as this proposed patch: the GPR5 bit is _always_ set
on a plus. The code does not check how the enet clock is generated.
Now, I'm assuming that the sabresd-plus can run on the Freescale
kernel fork. The GPR5 bit will always be set there.
So why won't mainline work with this patch? What have I overlooked?
I'm sure you've checked that sabresd ethernet works ok on mainline
even without this patch?
