One thing to consider is how this get merged. I assume you will have a
PHY driver patch soon making use of this? We can either:

1) Get Lee to merge it into the LED tree and then create a stable
branch which gets pulled into netdev.

2) Merge into netdev, with Lees Acked-by: 

It seems unlikely there will be any merge conflicts. So netdev does
seem like an O.K. way to go.

Yes, exactly. I'm working on adding support for LEDs to MaxLinear and
RealTek PHY drivers.

Via netdev (net-next) would be better imho as it would allow to add
changes to PHY drivers making use of the new constants without having
to wait for LED tree being merged.

Note that I've sent v2 which adds missing use of sysfs attributes.


Thank you!

I'll create an immutable branch.

The former solution does not prevent this.
