| description: | |
| 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. |
