+title: Broadcom's BCM63138 LEDs controller
+
+maintainers:
+ - Rafał Miłecki <rafal@milecki.pl>
+
+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.
