+Subject: [PATCH] dt-bindings: leds: add Broadcom's BCM63138 controller
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Broadcom used 2 LEDs hardware blocks for their BCM63xx SoCs:
+1. Older one (BCM6318, BCM6328, BCM6362, BCM63268, BCM6838)
+2. Newer one (BCM6848, BCM6858, BCM63138, BCM63148, BCM63381, BCM68360)
+
+The newer one was also later also used on BCM4908 SoC.
+
+Old block is already documented in the leds-bcm6328.yaml. This binding
+documents the new one which uses different registers & programming. It's
+first used in BCM63138 thus the binding name.

++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.
