Linux LEDs can be software controlled via the brightness file in /sys.
LED drivers need to implement a brightness_set function which the core
will call. Implement an intermediary in phy_device, which will call
into the phy driver if it implements the necessary function.

+ int (*led_brightness_set)(struct phy_device *dev,
+ u32 index, enum led_brightness value);

I think I would have made this an u8, 4 billion LEDs, man, that's a lot!

If andrew is ok we can still consider to reduce it. (but just to joke
about it... A MAN CAN DREAM OF A FULL HD SCREEN ON THEIR OWN SPECIAL
PORT)

Humm just thought of something else, is it OK for led_brightness_set and led_blink_set to call into functions that might require sleeping (MDIO, I2C, SPI, etc.)?
