10 - reg:			Should be the offset/length value for Flexcom dedicated
11 			I/O registers (without USART, TWI or SPI registers).
12 - clocks:		Should be the Flexcom peripheral clock from PMC.
13 - #address-cells:	Should be <1>
14 - #size-cells:		Should be <1>
15 - ranges:		Should be one range for the full I/O register region
16 			(including USART, TWI and SPI registers).
17 - atmel,flexcom-mode:	Should be one of the following values:
18 			- <1> for USART
19 			- <2> for SPI
20 			- <3> for I2C
