Use the csc library functions to configure the CSC block in VPE.
Some changes are required in try_fmt to handle the pix-colorspace parameter

The struct vpdma_data_format holds the color format depth and the data_type
value needed to be programmed in the data descriptors. However, it doesn't
tell what type of color format is it, i.e, whether it is RGB, YUV or Misc.
This information is needed when by vpdma library when forming
Add the required SC register configurations which lets us perform linear scaling
for the supported range of horizontal and vertical scaling ratios.
The horizontal scaler performs polyphase scaling using it's 8 tap 32 phase
filter, decimation is performed when downscaling passes beyond 2x or 4x.
The VPE and VIP IPs in DRA7x contain common scaler and color conversion hardware
blocks. We create libraries for these components such that the vpe driver and
the vip driver(in future) can use these library funcs to configure the blocks.
There are some points for which I would like comments:
-
Make the driver allocate dma buffers to store horizontal and scaler coeffs.
Use the scaler library api to choose and copy scaler coefficients to a
the above buffers based on the scaling ratio. Since the SC block comes after
the de-interlacer, make sure that the source height is doubled if
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

Hans,
My name is pat brown. I work for motorola solutions.
I am using a 8 megapixel camera and the lib4vl2 library is giving me an error:
libv4l2: error converting / decoding frame data: v4l-convert: error
destination buffer too small (16777216 23970816)
VIDIOC_DQBUF: Bad address
I think that needs device capability flag too (struct v4l2_capability)
but bits on that struct are quite short. Add it after V4L2_CAP_MODULATOR ?
OK, now all the API pieces seems to be there, so I am converting my existing
SDR drivers to that API and make some tests.
