This LEDs controller was first used on BCM63138 and later reused on BCM4908,
|
||
|
|
BCM6848, BCM6858, BCM63138, BCM63148, BCM63381 and BCM68360 SoCs.
|
||
|
|
|
||
|
|
It supports up to 32 LEDs that can be connected parallelly or serially. It
|
||
|
|
also includes limited support for hardware blinking.
|
||
|
|
|
||
|
|
Binding serially connected LEDs isn't documented yet.
