+* Device tree bindings for Atmel Flexcom (Flexible Serial Communication Unit)
+
+The Atmel Flexcom is just a wrapper which embeds a SPI controller, an I2C
+controller and an USART. Only one function can be used at a time and is chosen
+at boot time according to the device tree.
+
+Required properties:
+- compatible: "atmel,sama5d2-flexcom"
+- reg: shall be the offset/length value for Flexcom dedicated I/O registers
+  (without USART, TWI or SPI registers).
+- clocks: shall be the Flexcom peripheral clock from PMC.
+- #address-cells: should be <1>
+- #size-cells: should be <1>
+- ranges: must be present
+- atmel,flexcom-mode: shall be a string among { "spi", "usart", "i2c", "twi" }.
+  "i2c" and "twi" are synonymous.
+
+Example:
+
+flx0: flexcom@...34000 {
+	compatible = "atmel,sama5d2-flexcom";
+	reg = <0xf8034000 0x200>;
+	clocks = <&flx0_clk>;
+	#address-cells = <1>;
+	#size-cells = <1>;
+	ranges;
+	atmel,flexcom-mode = "spi";
+};
