* struct gpmi_platform_data - GPMI driver platform data.
*
* This structure communicates platform-specific information to the GPMI driver
* that can't be expressed as resources.
*
* @io_uA: The current limit, in uA.
* @min_prop_delay_in_ns: Minimum propagation delay of GPMI signals to and
* from the NAND Flash device, in nanoseconds.
* @max_prop_delay_in_ns: Maximum propagation delay of GPMI signals to and
* from the NAND Flash device, in nanoseconds.
* @pinmux_handler: A pointer to a function the driver will call to
* request the pins it needs.
* @boot_area_size_in_bytes: The amount of space reserved for use by the boot
* ROM on the first and second chips. If this value is
* zero, it indicates we're not reserving any space
* for the boot area.
* @partition_source_types: An array of strings that name sources of
* partitioning information (e.g., the boot loader,
* the kernel command line, etc.). The function
* parse_mtd_partitions() recognizes these names and
* applies the appropriate "plugins" to discover
* partitioning information. If any is found, it will
* be applied to the "general use" MTD (it will NOT
* override the boot area protection mechanism).
* @partitions: An optional pointer to an array of partition
* descriptions. If the driver finds no partitioning
* information elsewhere, it will apply these to the
* "general use" MTD (they do NOT override the boot
* area protection mechanism).
* @partition_count: The number of elements in the partitions array.
