+Nokia bluetooth UART devices
+------
+
+Some vendors have custom versions of their chips, that can be found in Nokia
+devices. These chips are controlled differently, than the non-Nokia version,
+so a different binding is required. All chips listed here implement the Nokia
+H4+ protocol.
+
+Required properties:
+
+ - compatible: should be one of the following:
+ * "nokia,brcm,bcm2048"
+ * "nokia,ti,wl1271-bluetooth"
+ - reset-gpios: Should specify the gpio for bluetooth reset
+ - host-wakeup-gpios: Should specify the gpio for host wakeup
+ - bluetooth-wakeup-gpios: Should specify the gpio for bluetooth wakeup
+ - clock-names: Should be "sysclk"
+ - clocks: Should contain a clock phandle for system clock
+
+Example:
+
+/ {
+ /* controlled (enabled/disabled) directly by wl1271 */
+ vctcxo: vctcxo {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <38400000>;
+ };
+};
+
+&uart2 {
+ bluetooth {
+ compatible = "nokia,ti,wl1271-bluetooth";
+
+ reset-gpios = <&gpio1 26 GPIO_ACTIVE_HIGH>; /* 26 */
+ host-wakeup-gpios = <&gpio4 5 GPIO_ACTIVE_HIGH>; /* 101 */
+ bluetooth-wakeup-gpios = <&gpio2 5 GPIO_ACTIVE_HIGH>; /* 37 */
+
+ clocks = <&vctcxo>;
+ clock-names = "sysclk";
+ };
+
+};
