I'm trying to configure VPIF driver for video capture from analog camera, connected through composite-in on my OMAP-L138 LCDK board.
I've configured menu config like this:

I've set bootargs for PAL like this:
vpif_capture.ch0_bufsize=831488 vpif_display.ch2_bufsize=831488
And I read,that I need to edit the support platform code in board file, located at "arch/arm/mach-davinci/board-omapl138-lcdkc".
I found recommended file board-omapl138-lcdkc.c and change the file in above directory on it.
And when I'm booting kernel, following error appears:
tvp514x: probe of 1-005d failed with error -5
vpif_capture vpif_capture: Error registering v4l2 subdevice
Can anybody explain:
How can I fix this error?
What is the board file needed for?
And how I should to change it for enabling VPIF driver?
I'm attaching my boot log, .config file and board file.(Please visit the site to view this file)(Please visit the site to view this file)(Please visit the site to view this file)
