0012 description: |
0013 This LEDs controller was first used on BCM63138 and later reused on BCM4908,
0014 BCM6848, BCM6858, BCM63138, BCM63148, BCM63381 and BCM68360 SoCs.
0015
0016 It supports up to 32 LEDs that can be connected parallelly or serially. It
0017 also includes limited support for hardware blinking.
0018
0019 Binding serially connected LEDs isn't documented yet.
