1 * Device tree bindings for Atmel Flexcom (Flexible Serial Communication Unit)
3 The Atmel Flexcom is just a wrapper which embeds a SPI controller, an I2C
4 controller and an USART. Only one function can be used at a time and is chosen
5 at boot time according to the device tree.
8 - compatible: Should be "atmel,sama5d2-flexcom"
9 or "microchip,sam9x7-flexcom", "atmel,sama5d2-flexcom"
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:
23 A single available child device of type matching the "atmel,flexcom-mode"
26 The phandle provided by the clocks property of the child is the same as one for
29 For other properties, please refer to the documentations of the respective
