+Subject: [PATCH 07/20] ARM: dts: imx6qdl-gw5910: add support for bcm4330-bt
+
+The Sterling-LWB has a BCM4330 which has a UART based bluetooth
+HCI. Add support for binding to the bcm_hci driver to take care
+of handling the shutdown gpio and loading firmware.
+
+Because the shutdown gpio is more of an enable than a regulator
+go ahead and replace the regulator with a shutdown-gpio.
