Hardware shutdown pin. If routed on the board, this property must be
|
|
present. Set to a logical 1 at boot to exit the device from hardware
|
|
shutdown.

Global current limit. Sets the global current control register of LED
|
|
driver (set table 14). Limits global current based on the following
|
|
formula: (840/R_ISET) * (current-limit/256). Defaults to max value
|
|
of 0xFF, so led output will still be enabled if property is
|
|
not provided.

This property configures the LED controller as a master or slave
|
|
clock device. This can be used to synchronize the output of multiple
|
|
LED controllers. See SYNC bits in led configuration register for more
|
|
information.
