+Required properties:
+
+	- compatible : must be "brcm,brcm-bt-uart".
+	- tty : tty device connected to this Bluetooth device.
+
+Optional properties:
+
+  - bt-host-wake-gpios : bt-host-wake input GPIO to be used as an interrupt.
+
+  - bt-wake-gpios : bt-wake output GPIO to be used to suspend / resume device.
+
+  - bt-reg-on-gpios : reg-on output GPIO to be used to power device on/off.
+
+  - oper-speed : Bluetooth device operational baud rate.
+    Default: 3000000.
+
+  - manual-fc : flow control UART in suspend / resume scenarios.
+    Default: 0.
+
+  - configure-sleep : configure suspend / resume flag.
+    Default: false.
+
+  - idle-timeout : Number of seconds of inactivity before suspending.
+    Default: 5.
+
+  - configure-audio : configure platform PCM SCO flag.
+    Default: false.
+
+  - pcm-clockmode : PCM clock mode. 0-slave, 1-master.
+    Default: 0.
+
+  - pcm-fillmethod : PCM fill method. 0 to 3.
+    Default: 2.
+
+  - pcm-fillnum : PCM number of fill bits. 0 to 3.
+    Default: 0.
+
+  - pcm-fillvalue : PCM fill value. 0 to 7.
+    Default: 3.
+
+  - pcm-incallbitclock : PCM interface rate. 0-128Kbps, 1-256Kbps, 2-512Kbps,
+    3-1024Kbps, 4-2048Kbps.
+    Default: 0.
+
+  - pcm-lsbfirst : PCM LSB first. 0 or 1.
+    Default: 0.
+
+  - pcm-rightjustify : PCM Justify. 0-left, 1-right.
+    Default: 0.
+
+  - pcm-routing : PCM routing. 0-PCM, 1-SCO over HCI.
+    Default: 0.
+
+  - pcm-shortframesync : PCM sync. 0-short, 1-long.
+    Default: 0.
+
+  - pcm-syncmode : PCM sync mode. 0-slave, 1-master.
+    Default: 0.
+

+Example:
+
+	bcm4354_bt_uart: bcm4354-bt-uart {
+		compatible = "brcm,brcm-bt-uart";
+		bt-wake-gpios =<&gpio4 30 GPIO_ACTIVE_HIGH>;
+		bt-host-wake-gpios =<&gpio4 31 GPIO_ACTIVE_HIGH>;
+		tty = "ttyS0";
