23 Abstract: EEPROM reader datastructures for 93cx6 chipsets.
24 Supported chipsets: 93c46, 93c56 and 93c66.
28 * EEPROM operation defines.
30 #define PCI_EEPROM_WIDTH_93C46 6
31 #define PCI_EEPROM_WIDTH_93C56 8
32 #define PCI_EEPROM_WIDTH_93C66 8
33 #define PCI_EEPROM_WIDTH_93C86 8
34 #define PCI_EEPROM_WIDTH_OPCODE 3
35 #define PCI_EEPROM_WRITE_OPCODE 0x05
36 #define PCI_EEPROM_ERASE_OPCODE 0x07
37 #define PCI_EEPROM_READ_OPCODE 0x06
38 #define PCI_EEPROM_EWDS_OPCODE 0x10
39 #define PCI_EEPROM_EWEN_OPCODE 0x13
42 * struct eeprom_93cx6 - control structure for setting the commands
43 * for reading the eeprom data.
44 * @data: private pointer for the driver.
45 * @register_read(struct eeprom_93cx6 *eeprom): handler to
46 * read the eeprom register, this function should set all reg_* fields.
47 * @register_write(struct eeprom_93cx6 *eeprom): handler to
48 * write to the eeprom register by using all reg_* fields.
49 * @width: eeprom width, should be one of the PCI_EEPROM_WIDTH_* defines
50 * @drive_data: Set if we're driving the data line.
51 * @reg_data_in: register field to indicate data input
52 * @reg_data_out: register field to indicate data output
53 * @reg_data_clock: register field to set the data clock
54 * @reg_chip_select: register field to set the chip select
56 * This structure is used for the communication between the driver
57 * and the eeprom_93cx6 handlers for reading the eeprom.
