i2c: 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

i2c: slave eeprom: clean up sysfs bin attribute read()/write()

2015-07-31T11:32:30+00:00

The change removes redundant sysfs binary file boundary checks, since this task is already done on caller side in fs/sysfs/file.c Note, on file size overflow read() now returns 0, and this is a correct and expected EOF notification according to POSIX.

i2c: slave-eeprom: add more info when to increase the pointer

2015-03-27T15:53:40+00:00

It is a bit subtle when to correctly increase the buffer index when reading. Make this clearer by adding some more comments and pointers to the docs. Signed-off-by: Wolfram Sang Acked-by: Uwe Kleine-König Signed-off-by: Wolfram Sang

i2c: slave: rework the slave API

2015-03-27T15:53:38+00:00

After more discussion, brave users, and additional datasheet evaluation, some API updates for the new I2C slave framework became imminent. The slave events now get some easier to understand naming. Also, the event handling has been simplified to only need a single call to the slave callback when an action by the backend is required.

i2c: slave-eeprom: fix boundary check when using sysfs

2015-01-24T04:43:44+00:00

Due to a copy&paste error, the last byte of the shared memory was not accessible via sysfs. Reported-by: Debora Grosse Signed-off-by: Wolfram Sang Acked-by: Laurent Pinchart Signed-off-by: Wolfram Sang

i2c: slave-eeprom: add eeprom simulator driver

2014-12-11T21:25:54+00:00

The first user of the i2c-slave interface is an eeprom simulator. It is a shared memory which can be accessed by the remote master via I2C and locally via sysfs. Signed-off-by: Wolfram Sang Signed-off-by: Wolfram Sang
