eeprom: at24: use i2c_smbus_read_i2c_block_data_or_emulated

2015-08-24T12:05:20+00:00

For i2c busses that support only SMBUS extensions, the eeprom at24 driver reads data from the device using the SMBus block, word or byte read protocols depending on availability. Replace the block read emulation from the driver with the i2c_smbus_read_i2c_block_data_or_emulated call from i2c core. Signed-off-by: Irina Tirdea Signed-off-by: Wolfram Sang

misc: Drop owner assignment from i2c_driver

2015-08-10T06:37:35+00:00

i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Wolfram Sang

misc: eeprom: at24: clean up at24_bin_write()

2015-07-31T11:32:31+00:00

The change removes redundant sysfs binary file boundary check, since this task is already done on caller side in fs/sysfs/file.c Signed-off-by: Vladimir Zapolskiy Signed-off-by: Wolfram Sang

eeprom: at24: extend driver to allow writing via i2c_smbus_write_byte_data

2014-11-17T18:54:22+00:00

I have a at24 EEPROM connected via i2c bus provided by ISCH i2c bus driver. This bus driver does not support I2C_FUNC_SMBUS_WRITE_I2C_BLOCK and so I was looking for a way to be able to write the eeprom. This patch adds support for I2C_SMBUS_BYTE_DATA writing via i2c_smbus_write_byte_data. It is quite slow, but it works.

misc/at24: avoid infinite loop on write()

2013-10-29T23:24:33+00:00

This change fixes a problem of infinite zero byte write() without an error status, if there is an attempt to write a file bigger than EEPROM size over sysfs interface. Signed-off-by: Vladimir Zapolskiy Cc: Wolfram Sang Cc: Greg Kroah-Hartman Signed-off-by: Greg Kroah-Hartman

misc: (at24) move header to linux/platform_data/

2013-09-30T04:02:34+00:00

This patch moves the at24.h header from include/linux/i2c to include/linux/platform_data and updates existing support accordingly. It also fixes the following checkpatch warning: WARNING: please, no space before tabs #436: FILE: include/linux/platform_data/at24.h:31: + * ^Iu8 *mac_addr = ethernet_pdata->mac_addr;$ Signed-off-by: Vivien Didelot Signed-off-by: Wolfram Sang
