+* CSR SiRFprimaII/atlasVI Universal Synchronous Asynchronous Receiver/Transmitter *
+
+Required properties:
+- compatible : Should be "sirf,prima2-uart", "sirf, prima2-usp-uart",
+ "sirf,atlas7-uart" or "sirf,atlas7-bt-uart" which means
+ uart located in BT module and used for BT.
+- reg : Offset and length of the register set for the device
+- interrupts : Should contain uart interrupt
+- fifosize : Should define hardware rx/tx fifo size
+- clocks : Should contain uart clock number
+
+Optional properties:
+- sirf,uart-has-rtscts: we have hardware flow controller pins in hardware
+- rts-gpios: RTS pin for USP-based UART if sirf,uart-has-rtscts is true
+- cts-gpios: CTS pin for USP-based UART if sirf,uart-has-rtscts is true
+
+Example:
+
+uart0: uart@b0050000 {
+ cell-index = <0>;
+ compatible = "sirf,prima2-uart";
+ reg = <0xb0050000 0x1000>;
+ interrupts = <17>;
+ fifosize = <128>;
+ clocks = <&clks 13>;
+};
+
+On the board-specific dts, we can put rts-gpios and cts-gpios like
+
+usp@b0090000 {
+ compatible = "sirf,prima2-usp-uart";
+ sirf,uart-has-rtscts;
+ rts-gpios = <&gpio 15 0>;
+ cts-gpios = <&gpio 46 0>;
+};
+
+for uart use in BT module,
+uart6: uart@11000000 {
+ cell-index = <6>;
+ compatible = "sirf,atlas7-bt-uart", "sirf,atlas7-uart";
+ reg = <0x11000000 0x1000>;
+ interrupts = <0 100 0>;
+ clocks = <&clks 138>, <&clks 140>, <&clks 141>;
+ clock-names = "uart", "general", "noc";
+ fifosize = <128>;
+ status = "disabled";
+}
