I'd be happier if the sentences started with uppercase letters, but nothing too offensive or controversial here: Acked-by: Lee Jones <lee.jones@linaro.org> > +Example: > + > +smc: smc@ffffc000 { > + compatible = "atmel,sama5d3-smc", "syscon"; > + reg = <0xffffc000 0x1000>; > +};

The SMC registers are used to configure Atmel EBI (External Bus Interface) to interface with standard memory devices (NAND, NOR, SRAM or specialized devices like FPGAs). Declare this memory region as a syscon, so that different drivers can configure the SMC interface (mostly timing configuration) according to their need.
