-* 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:		Should be "atmel,sama5d2-flexcom"
-- reg:			Should be the offset/length value for Flexcom dedicated
-			I/O registers (without USART, TWI or SPI registers).
-- clocks:		Should be the Flexcom peripheral clock from PMC.
-- #address-cells:	Should be <1>
-- #size-cells:		Should be <1>
-- ranges:		Should be one range for the full I/O register region
-			(including USART, TWI and SPI registers).
-- atmel,flexcom-mode:	Should be one of the following values:
-			- <1> for USART
-			- <2> for SPI
-			- <3> for I2C
-
-Required child:
-A single available child device of type matching the "atmel,flexcom-mode"
-property.
-
-The phandle provided by the clocks property of the child is the same as one for
-the Flexcom parent.
-
-For other properties, please refer to the documentations of the respective
-device:
-- ../serial/atmel-usart.txt
-- ../spi/spi_atmel.txt
-- ../i2c/i2c-at91.txt
-
-Example:
-
-flexcom@f8034000 {
-	compatible = "atmel,sama5d2-flexcom";
-	reg = <0xf8034000 0x200>;
-	clocks = <&flx0_clk>;
-	#address-cells = <1>;
-	#size-cells = <1>;
-	ranges = <0x0 0xf8034000 0x800>;
-	atmel,flexcom-mode = <2>;
-
-	spi@400 {
-		compatible = "atmel,at91rm9200-spi";
-		reg = <0x400 0x200>;
-		interrupts = <19 IRQ_TYPE_LEVEL_HIGH 7>;
-		pinctrl-names = "default";
-		pinctrl-0 = <&pinctrl_flx0_default>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		clocks = <&flx0_clk>;
-		clock-names = "spi_clk";
-		atmel,fifo-size = <32>;
-
-		flash@0 {
-			compatible = "atmel,at25f512b";
-			reg = <0>;
-			spi-max-frequency = <20000000>;
-		};
-	};
-};
