    lan78xx: Read LED states from Device Tree · 1827b067
    Phil Elwell authored
    Add support for DT property "microchip,led-modes", a vector of zero
    to four cells (u32s) in the range 0-15, each of which sets the mode
    for one of the LEDs. Some possible values are:
    
        0=link/activity          1=link1000/activity
        2=link100/activity       3=link10/activity
        4=link100/1000/activity  5=link10/1000/activity
        6=link10/100/activity    14=off    15=on
    
    These values are given symbolic constants in a dt-bindings header.
    
    Also use the presence of the DT property to indicate that the
    LEDs should be enabled - necessary in the event that no valid OTP
    or EEPROM is available.
