+
+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.
+
+ - baud-rate-before-config-download : initial Bluetooth device baud rate.
+ Default: 3000000.
+
+ - manual-fc : flow control UART in suspend / resume scenarios.
+ Default: 0.
+
+ - configure-sleep : configure suspend / resume flag.
+ Default: false.
+
+ - configure-audio : configure platform PCM SCO flag.
+ Default: false.
+
+ - PCMClockMode : PCM clock mode. 0-slave, 1-master.
+ Default: 0.
+
+ - PCMFillMethod : PCM fill method. 0 to 3.
+ Default: 2.
+
+ - PCMFillNum : PCM number of fill bits. 0 to 3.
+ Default: 0.
+
+ - PCMFillValue : PCM fill value. 0 to 7.
+ Default: 3.
+
+ - PCMInCallBitclock : PCM interface rate. 0-128Kbps, 1-256Kbps, 2-512Kbps,
+ 3-1024Kbps, 4-2048Kbps.
+ Default: 0.
+
+ - PCMLSBFirst : PCM LSB first. 0 or 1.
+ Default: 0.
+
+ - PCMRightJustify : PCM Justify. 0-left, 1-right.
+ Default: 0.
+
+ - PCMRouting : PCM routing. 0-PCM, 1-SCO over HCI.
+ Default: 0.
+
+ - PCMShortFrameSync : PCM sync. 0-short, 1-long.
+ Default: 0.
+
+ - PCMSyncMode : PCM sync mode. 0-slave, 1-master.
+ Default: 0.
+
+
+Example:
+
+ brcm4354_bt_uart: brcm4354-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";
+ baud-rate-before-config-download = <3000000>;

+ PCMClockMode = <0>;
+ PCMFillMethod = <2>;
+ PCMFillNum = <0>;
+ PCMFillValue = <3>;
+ PCMInCallBitclock = <0>;
+ PCMLSBFirst = <0>;
+ PCMRightJustify = <0>;
+ PCMRouting = <0>;
+ PCMShortFrameSync = <0>;
+ PCMSyncMode = <0>;
