net: phy: aquantia: add support for PHY LEDs
Aquantia Ethernet PHYs got 3 LED output pins which are typically used to indicate link status and activity. Add a minimal LED controller driver supporting the most common uses with the 'netdev' trigger as well as software-driven forced control of the LEDs. Signed-off-by: Daniel Golle <daniel@makrotopia.org> [ rework indentation, fix checkpatch error and improve some functions ] Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
