The ti-vpe/ sub-directory does not only contain the VPE-specific things.
It also contains the CAL driver, which is a completely different
subsystem. This is also not a good place to add new drivers for other TI
platforms since they will all get mixed up.
Separate the VPE and CAL parts into different sub-directories and rename
the ti-vpe/ sub-directory to ti/. This is now the place where new TI
platform drivers can be added.

There is an error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant

In csc_set_coeff() we were previously checking if the format type was
V4L2_BUF_TYPE_VIDEO_OUTPUT or V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE as a
mean to figure out if the format was multiplanar or not. This was not
entirely accurate as the format type could also be a CAPTURE type
instead.
Fix this by removing the 'switch' construct and replacing them with
"if (V4L2_TYPE_IS_MULTIPLANAR(type))" instead.

There appears to be a copy-paste error on the access of
csc_coeffs.y2r.r601.full.coeff, I believe csc_coeffs.2yr.r601.full.coeff
should be used instead. This is a moot point as the code is never
reached, but at least use the correct structure element.

Up to now VPE was relying on the colorspace value of struct v4l2_format
as an indication to perform color space conversion from YUV to RGB or
not.
Instead we should used the source/destination fourcc codes as a more
reliable indication to perform color space conversion or not.
To do so, we rework the csc module to use "struct v4l2_format *" as
parameters, and reorganize the coefficients tables in a more logical
way.

The RGB to YUV HD full range coefficients did not match the TRM values
and appeared to be a cut-n-paste from the YUV to RGB section.
Replace the entries with the values from the TRM.

Replace the use of nested functions where a normal function will suffice.
Nested functions are not liked by upstream kernel developers in general. Their
use breaks the use of clang as a compiler, and doesn't make the code any
better.
This code now works for both gcc and clang.

Rename the memory block resource "vpe_csc" to "csc" since it also exists within
the VIP IP block. This would make the name more generic, and both VPE and VIP DT

The CSC block can be used for color space conversion between YUV and RGB
formats.
It is configurable via a programmable set of coefficients. Add functionality to
choose the appropriate CSC coefficients and program them in the CSC registers.
We take the source and destination colorspace formats as the arguments, and
choose the coefficient table accordingly.
YUV to RGB coefficients are provided for standard and high definition
colorspaces. The coefficients can also be limited or full range. For now, only
full range coefficients are chosen. We would need some sort of control ioctl for
the user to specify the range needed. Not sure if there is a generic control
ioctl for this already?

VPE and VIP IPs in DAR7x contain a color space converter(CSC) sub block. Create
a library which will perform CSC related configurations and hold CSC register
definitions. The functions provided by this library will be called by the vpe
and vip drivers using a csc_data handle.
The vpe_dev holds the csc_data handle. The handle represents an instance of the
CSC hardware, and the vpe driver uses it to access the CSC register offsets or
helper functions to configure these registers.
The CSC register offsets are now relative to the CSC block itself, so we need
to use the macro GET_OFFSET_TOP to get the CSC register offset relative to the
VPE IP in the vpe driver.
