3b10db23c0 i2c: dln2: set the device tree node of the adapter 
This patch makes sure the platform device tree node is inherited by
the adapter device. This allows the DLN2 bus to work with i2c devices
defined in the device tree.

db23e5001f i2c: add support for Diolan DLN-2 USB-I2C adapter 
This patch adds support for the Diolan DLN-2 I2C master module. Due
to hardware limitations it does not support SMBUS quick commands.

Information about the USB protocol interface can be found in the
Programmer's Reference Manual [1], see section 6.2.2 for the I2C
master module commands and responses.
