3  * Linux I2C core SMBus and SMBus emulation code
5  * This file contains the SMBus functions which are always included in the I2C
6  * core because they can be emulated via I2C. SMBus specific extensions
7  * (e.g. smbalert) are handled in a separate i2c-smbus module.
9  * All SMBus-related things are written by Frodo Looijaard <frodol@dds.nl>
10  * SMBus 2.0 support by Mark Studebaker <mdsxyz123@yahoo.com> and
16 #include <linux/i2c-smbus.h>

110  * This executes the SMBus "send byte" protocol, returning negative errno
121  * i2c_smbus_read_byte_data - SMBus "read byte" protocol
125  * This executes the SMBus "read byte" protocol, returning negative errno

239  * This executes the SMBus "block write" protocol, returning negative errno
310  * Simulate a SMBus command using the I2C protocol.
520  * i2c_smbus_xfer - execute SMBus protocol operations
522  * @addr: Address of SMBus slave on that bus
526  * @protocol: SMBus protocol operation to execute, such as I2C_SMBUS_PROC_CALL
529  * This executes an SMBus protocol operation, and returns a negative

622  * @length: Size of data block; SMBus allows at most I2C_SMBUS_BLOCK_MAX bytes
624  *	the data returned by the slave.  SMBus allows at most
627  * This executes the SMBus "block read" protocol if supported by the adapter.
676  * i2c_new_smbus_alert_device - get ara client for SMBus alert support
678  * @setup: setup data for the SMBus alert handler
681  * Setup handling of the SMBus alert protocol on a given I2C bus segment.
