----------------------------------------------------------
-
-Required properties:
-- compatible : Can be either of
- "xlnx,xps-uartlite-1.00.a"
- "xlnx,opb-uartlite-1.00.b"
-- reg : Physical base address and size of the Axi Uartlite
- registers map.
-- interrupts : Should contain the UART controller interrupt.
-
-Optional properties:
-- port-number : Set Uart port number
-- clock-names : Should be "s_axi_aclk"
-- clocks : Input clock specifier. Refer to common clock bindings.
-
-Example:
-serial@800c0000 {
- compatible = "xlnx,xps-uartlite-1.00.a";
- reg = <0x0 0x800c0000 0x10000>;
- interrupts = <0x0 0x6e 0x1>;
- port-number = <0>;
-};
