+Subject: [PATCH] rpi: Enable USB Power domain during startup
+
+Enable the USB Power domain during startup. The power domain is
+abstracted as a regulator in barebox, but modelled as a power domain in
+the device tree. Until this is sorted out just enable the power domain
+or regulator in the board code.
