| 12 | description: | |
| 13 | This LEDs controller was first used on BCM63138 and later reused on BCM4908, |
| 14 | BCM6848, BCM6858, BCM63138, BCM63148, BCM63381 and BCM68360 SoCs. |
| 15 | |
| 16 | It supports up to 32 LEDs that can be connected parallelly or serially. It |
| 17 | also includes limited support for hardware blinking. |
| 18 | |
| 19 | Binding serially connected LEDs isn't documented yet. |
