2014-07-14	bfea711 Browse files » i2c: import SMBus stuff from linux ... This patch imports i2c_smbus_{read,write}* functions from linux-3.15. Here is a quote from linux.git/Documentation/i2c/smbus-protocol: If you write a driver for some I2C device, please try to use the SMBus commands if at all possible (if the device uses only that subset of the I2C protocol). This makes it possible to use the device driver on both SMBus adapters and I2C adapters (the SMBus command set is automatically translated to I2C on I2C adapters, but plain I2C commands can not be handled at all on most pure SMBus adapters). So having i2c_smbus_{read,write}* functions in barebox makes porting of linux i2c client drivers much easier as many drivers rely on these smbus functions.

This driver to get read/write support to most I2C EEPROMs, after you configure the driver to know about each EEPROM on your target board. Use these generic chip names, instead of vendor-specific ones like at24c64 or 24lc02: 24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08, 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024 Unless you like data loss puzzles, always be sure that any chip you configure as a 24c32 (32 kbit) or larger is NOT really a 24c16 (16 kbit) or smaller, and vice versa. Marking the chip as read-only won't help recover from this. Also, if your chip has any software write-protect mechanism you may want to review the code to make sure this driver won't turn it on by accident.
