| * struct gpmi_nand_platform_data - GPMI NAND driver platform data. |
| * |
| * This structure communicates platform-specific information to the GPMI NAND |
| * driver that can't be expressed as resources. |
| * |
| * @platform_init: A pointer to a function the driver will call to |
| * initialize the platform (e.g., set up the pin mux). |
| * @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. |
| * @max_chip_count: The maximum number of chips for which the driver |
| * should configure the hardware. This value most |
| * likely reflects the number of pins that are |
| * connected to a NAND Flash device. If this is |
| * greater than the SoC hardware can support, the |
| * driver will print a message and fail to initialize. |
| * @partitions: An optional pointer to an array of partition |
| * descriptions. |
| * @partition_count: The number of elements in the partitions array. |
