* @in_off:: The line size in bytes for output buffer.
* ispdss_begin() takes the input buffer index and output buffer index
* to start the process of resizing. after resizing is complete,
* the callback function will be called with the argument.
* Indexes of the input and output buffers are used so that it is faster
* and easier to configure the input and output address for the ISP resizer.
* As per the current implementation, DSS uses six VRFB contexts for rotation.
* for both input and output buffers index and physical address has been taken
* as argument. if this buffer is not already mapped to ISP address space we
* use physical address to map it, otherwise only the index is used.
