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. This pointer may be NULL. + * + * For some i.MX SoC's, the NFC gets information about the + * page size from signals driven by a system register + * outside the NFC. The address and format of this external + * register varies across SoC's. In other SoC's, the NFC + * still receives this signal, but it is overridden by a + * page size register in the NFC itself. + * + * For SoC's where the page size *must* be set in an + * external register, the driver must rely on a platform- + * specific function, and this member must point to it. + * + * For SoC's where the NFC has its own page size register, + * the driver will set that register itself and ignore the + * external signals. In this case, there's no need for the + * platform-specific function and this member must be NULL. + * + * This function accepts the page size in bytes (MTD calls + * this the "writesize") discovered by the NAND Flash MTD + * base driver (e.g., 512, 2048, 4096). This size refers + * specifically to the the data bytes in the page, *not* + * including out-of-band bytes. The return value is zero if + * the operation succeeded. The driver does *not* view a + * non-zero value as an error code - only an indication of + * failure. The driver will decide for itself what error + * code to return to its caller. + * @interleave: Indicates that the driver should "interleave" the NAND + * Flash chips it finds. If true, the driver will aggregate + * the chips "horizontally" such that MTD will see a single + * chip with a potentially very large page size. This can + * improve write performance for some applications. + * @partitions: An optional pointer to an array of partitions.
