From 1a6ab1c0e844041524f8edd1acf0de94df991aaa Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Thu, 13 Nov 2014 12:47:45 +0100 Subject: [PATCH] Phy: DT binding documentation for the Armada 375 USB cluster binding Armada 375 comes with an USB2 host and device controller and an USB3 controller. The USB cluster control register allows to manage common features of both USB controllers. This commit adds the Device Tree binding documentation for this piece of hardware.
