+Subject: [PATCH] ARM: BCM5301X: Set vcc-gpio for USB controllers of few
+ devices
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+There are few devices that have USB power controlled using GPIO. Linux
+USB host driver (bcma-hcd) already supports this by reading vcc-gpio
+from DT. Set it properly for all known devices.
