Re: [PATCH 1/1 RFC] net/phy: Add Lantiq PHY driver

For LEDs, we had a patch series floating around adding LED triggers [1],
and it seems to me like the LEDs class subsystem would be a good fit for
controlling PHY LEDs, possibly with the help of PHYLIB when it comes to
doing the low-level work of registering LEDs and their names with the
LEDS subsystem.

That patch fizzled out. I got the feeling it was pushing the
capabilities of the coder. I do however think it is a reasonable path
to follow for PHY LEDs.

I took a quick look at the datasheet and the controlling of the LEDs
is very flexible. It should not be a problem to expose some of that
functionality via LED triggers.

To be honest I don't know how the PHY LEDs could be set by LED triggers. 
Wouldn't that require to create triggers for each value which can be written 
to LEDxH and LEDxL? In my case the hardware requires some specific setting due 
to LED connections.
Of course making the LED configuration changeable at runtime would be awesome.
