* @param InstancePtr is a pointer to the XDp instance.
|

* @param LinkCountTotal is the number of DisplayPort links from the

* DisplayPort source to the target DisplayPort device.
|

* @param RelativeAddress is the relative address from the DisplayPort
|
||||
* source to the target DisplayPort device.
|

* @param IicDeviceId is the address on the I2C bus of the target device.

* @param BytesToWrite is the number of bytes to write to the I2C address.
|

* @param WriteData is a pointer to a buffer that will be written.

* successfully obtained and it indicates an acknowledge.
