thanks for this patch!

How do we handle patches for drivers which will (unfortunately) not
land in the linux 4.8 - should I integrate that into v3 of the patch
(which I'll have to send anyways) or do we keep them separate?
Maybe Kishon and/or Kevin can share their opinion on this.


Regards,
Martin

It's up to Kishon if he wants a v3, or if he can fold in the fix
himself.

Since you are anyways planning to send v3, merge this patch too.

Thanks

I got confused why this driver appears in linux-next but it's not from phy
tree? I thought it's because other dependency so it needs to go via other tree,
but looks like not the case. And the driver does not get Kishon's Ack?

BTW, Kishon, do you consider to add phy tree to linux-next?

That was my fault, it got (mistakenly) included in the branch I submit
to linux-next for the amlogic SoC support.
