Subject: [PATCH v2 1/2] dt-bindings: serial: add documentation for the SiFive UART driver
Date: Fri, 19 Oct 2018 11:48:27 -0700

Message-ID: <20181019184827.M5taTgscxROg-bx3zL-G9cN8l3k_kQ0On9hKYdKZNXQ@z> (raw)
In-Reply-To: <20181019184827.12351-1-paul.walmsley@sifive.com>

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>;
+};
