Document the i2c_adapter fields that must be initialized before
calling i2c_add_adapter().

This patch adds two new sysfs files, bus_frequency and
bus_supported_frequencies which allows the user to view or change the
bus frequency on a per bus level.
This is required for e.g. USB I2C buses where we can have multiple
device plugged in a system and where a module parameter does not allow

This patch adds Documentation/ABI/testing/sysfs-bus-i2c which

The first two patches are just general cleanup the actual
implementation is in patch 3. If the general direction looks
acceptable, I will send a follow-up series that adds sysfs bus
frequency support to the existing drivers.

Some GPIO chips (e.g. the DLN2 USB adapter) have blocking get/set
operation but do not need a threaded irq handler.

This patch adds support for the Diolan DLN-2 I2C master module. Due
to hardware limitations it does not support SMBUS quick commands.

Hi,
1. You are going to want to resend your patch using git-send-mail, you
used an email client that destroyed all formatting. gmail in
particular is good at breaking things so your patch cannot be applied
correctly.
2. You need to add a Signed-off-by line like other patches people submit.

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.

There is no need to init .owner field.
Based on the patch from Peter Griffin
"mmc: remove .owner field for drivers using module_platform_driver"
This patch removes the superfluous .owner field for drivers which
use the module_platform_driver API, as this is overridden in
platform_driver_register
