Set this value to the maximum of these + * two parameters. The driver will set the NFC clock as + * close as possible without violating this value. + * @clock_name: The name of the clock used by the NAND Flash controller. + * @init: A pointer to a function the driver must call so the + * platform can prepare for this device to operate. This + * pointer may be NULL. + * @exit: A pointer to a function the driver must call so the + * platform clean up after this device stops operating. + * This pointer may be NULL. + * @set_page_size: A pointer to a function the driver can call to set the + * page size.
