Subject: [PATCH 1/2] dt-bindings: serial: add documentation for the SiFive UART driver

Add DT binding documentation for the Linux driver for the SiFive
asynchronous serial IP block. Nothing too exotic.

+SiFive asynchronous serial interface (UART)
+
+Required properties:
+
+- compatible: should be "sifive,fu540-c000-uart0" or "sifive,uart0"
+- reg: address and length of the register space
+- interrupt-parent: should contain a phandle pointing to the SoC interrupt
+ controller device node that the UART interrupts are connected to
+- interrupts: Should contain the UART interrupt identifier
+- clocks: Should contain a clock identifier for the UART's parent clock
+
+
+Example:
+
+uart0: serial@10010000 {
+ compatible = "sifive,uart0";
+ interrupt-parent = <&plic0>;
+ interrupts = <80>;
+ reg = <0x0 0x10010000 0x0 0x1000>;
+ clocks = <&prci PRCI_CLK_TLCLK>;
