This is for the DM6446, not the 355, but I found that I had to modify
ti-davinci/drivers/media/video/Kconfig and ti-davinci/include/media/
davinci/ vid_encoder_types.h as well.

You right with your approach. Add a new encoder.c file and add your
VPBE hardware setup function to davinci_platform.c. You'll also need
to define a new mode and output to be used on the uBoot kernel boot
arguments.

Hello All,
Currently I am working on the Video Encoder driver for Davinci DMS
355. I need to implement the LCD encoder which is not available in
the existing code.
I have gone through the existing code for display driver and the
user guide document for LSp1.20 Davinci Linux V4L2 Display Driver.
The PDF name is SPRUEL3.pdf.
As per the video architecture, there are different layers like
Encoder Manager, Display manager, Display Platform, Logic PD
encoder, THS8200 encoder. These layers are interacting with the
hardware.
If I want to add the new Encoder driver, I have to add that driver
file parallel to the Logic PD encoder driver/THS8200. Is my
understanding is correct?
Also, I may need to modify the Display manager (Davinci_dislpay.c)
and Display platform (davinci_platform.c) related code. These files
are the driver files for VPBE module. Rest of the video related
code can be reused without any change.
I want to know, whether this approach is correct for implementing
the new encoder driver?
If someone who worked on the Video encoder, please provide your
valuable comments.
Thanks a lot in advance.
Regards,
Prabhaharan.R
