DW100 dewarp driver
===================
The Vivante DW100 Dewarp Processor IP core found on i.MX8MP SoC applies a
programmable geometrical transformation on the input image to correct distortion
introduced by lenses.
The transformation function is exposed by the hardware as a grid map with 16x16
pixel macroblocks indexed using X, Y vertex coordinates.

Grid of Image Blocks for Dewarping Map
Each x, y coordinate register uses 16 bits to record the coordinate address in
an unsigned 12.4 fixed point format (UQ12.4).

Remap Register Layout
The dewarping map is set from applications using the
V4L2_CID_DW100_DEWARPING_16x16_VERTEX_MAP control. The control contains
an array of u32 values storing (x, y) destination coordinates for each
vertex of the grid. The x coordinate is stored in the 16 LSBs and the y
coordinate in the 16 MSBs.
The number of elements in the array must match the image size:
.. code-block:: C
elems = (DIV_ROUND_UP(width, 16) + 1) * (DIV_ROUND_UP(height, 16) + 1);
If the control has not been set by the application, the driver uses an identity
map.
More details on the DW100 hardware operations can be found in
*chapter 13.15 DeWarp* of IMX8MP_ reference manual.
The Vivante DW100 m2m driver implements the following driver-specific control:
``V4L2_CID_DW100_DEWARPING_16x16_VERTEX_MAP (__u32 array)``
Specifies to DW100 driver its dewarping map (aka LUT) blob as described in
*chapter 13.15.2.3 Dewarping Remap* of IMX8MP_ reference manual as an U32
dynamic array. The image is divided into many small 16x16 blocks. If the
width/height of the image is not divisible by 16, the size of the
rightmost/bottommost block is the remainder. The dewarping map only saves
the vertex coordinates of the block. The dewarping grid map is comprised of
vertex coordinates for x and y. Each x, y coordinate register uses 16 bits
(UQ12.4) to record the coordinate address, with the Y coordinate in the
upper bits and X in the lower bits. The driver modifies the dimensions of
this control when the sink format is changed, to reflect the new input
resolution.

/* Should ease the (re-)usage of drivers supporting cards with (different)
video codecs. The codecs register to this module their functionality,
and the processors (masters) can attach to them if they fit.
The codecs are typically have a "strong" binding to their master - so I
don't think it makes sense to have a full blown interfacing as with e.g.
i2c. If you have an other opinion, let's discuss & implement it :-)))
Usage:
The slave has just to setup the videocodec structure and use two functions:
videocodec_register(codecdata);
videocodec_unregister(codecdata);
The best is just calling them at module (de-)initialisation.
The master sets up the structure videocodec_master and calls:
codecdata=videocodec_attach(master_codecdata);
videocodec_detach(codecdata);
The slave is called during attach/detach via functions setup previously
during register. At that time, the master_data pointer is set up
and the slave can access any io registers of the master device (in the case
the slave is bound to it). Otherwise it doesn't need this functions and
therfor they may not be initialized.
The other functions are just for convenience, as they are for sure used by
most/all of the codecs. The last ones may be omitted, too.
See the structure declaration below for more information and which data has
to be set up for the master and the slave.
----------------------------------------------------------------------------
The master should have "knowledge" of the slave and vice versa. So the data
structures sent to/from slave via set_data/get_data set_image/get_image are
device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)
