no.
It means.. DO NOT define dmc0 and dmc1 separately.
We need dmc base and we can access  dmc1.
For example, uart have 4 devices but we defined uart0 address as UART's base.
and access by offset.

	u32 offset = dev_index * sizeof(struct s5p_uart);
	return (struct s5p_uart *)(samsung_get_base_uart() + offset);

no.
