+Binding for Conexant Digicolor USART
+
+Note: this binding is only applicable for using the USART peripheral as
+UART. USART also support synchronous serial protocols like SPI and I2S. Use
+the binding that matches the wiring of your system.
+
+Required properties:
+- compatible : should be "cnxt,cx92755-usart".
+- reg: Should contain USART controller registers location and length.
+- interrupts: Should contain a single USART controller interrupt.
+- clocks: Must contain phandles to the USART clock
+ See ../clocks/clock-bindings.txt for details.
+
+Note: Each UART port should have an alias correctly numbered
+in "aliases" node.
+
+Example:
+ aliases {
+ serial0 = &uart0;
+ };
+
+ uart0: uart@f0000740 {
+ compatible = "cnxt,cx92755-usart";
+ reg = <0xf0000740 0x20>;
+ clocks = <&main_clk>;
+ interrupts = <44>;
+ };
