void eeprom_93cx6_multiread	(	struct eeprom_93cx6 *	eeprom,
		const u8	word,
		__le16 *	data,
		const u16	words
	)

eeprom_93cx6_multiread - Read multiple words from eeprom : Pointer to eeprom structure : Word index from where we should start reading : target pointer where the information will have to be stored : Number of words that should be read.

This function will read all requested words from the eeprom, this is done by calling eeprom_93cx6_read() multiple times. But with the additional change that while the eeprom_93cx6_read will return host ordered bytes, this method will return little endian words.

void eeprom_93cx6_read	(	struct eeprom_93cx6 *	eeprom,
		const u8	word,
		u16 *	data
	)

eeprom_93cx6_read - Read multiple words from eeprom : Pointer to eeprom structure : Word index from where we should start reading : target pointer where the information will have to be stored

This function will read the eeprom data as host-endian word into the given data pointer.

void eeprom_93cx6_wren	(	struct eeprom_93cx6 *	eeprom,
		bool	enable
	)

eeprom_93cx6_wren - set the write enable state : Pointer to eeprom structure : true to enable writes, otherwise disable writes

Set the EEPROM write enable state to either allow or deny writes depending on the value.

void eeprom_93cx6_write	(	struct eeprom_93cx6 *	eeprom,
		u8	addr,
		u16	data
	)

eeprom_93cx6_write - write data to the EEPROM : Pointer to eeprom structure : Address to write data to. : The data to write to address .

Write the to the specified in the EEPROM and waiting for the device to finish writing.

Note, since we do not expect large number of write operations we delay in between parts of the operation to avoid using excessive amounts of CPU time busy waiting.
