Composite Video on Beagle Board

Hello All,
I am trying to get Composite Video working on Beagle Board.
I am using 2.6.29rc3 with DSS2 changes included in them.
I changed the default .u.venc.type to OMAP_DSS_VENC_TYPE_COMPOSITE in arch/arm/mach-omap2/board-omap3beagle.c
When I tried executing the instructions present in the DSS documentation (Clone GFX overlay to LCD and TV),
I could not get Composite Video working.

As I started debugging the code, I see that all the settings are getting reflected properly.
The resolution is set to 720 * 574, venc type is OMAP_DSS_VENC_TYPE_COMPOSITE,
dispc_go function in dispc.c is being called with omap channel set to OMAP_DSS_CHANNEL_DIGIT.

But in dispc_go function: I always hit with “if the channel is not enabled, we don’t need GO” condition and comes out of the function.
The following is the code snippet:

*********************** CODE START ***********************
if (channel == OMAP_DSS_CHANNEL_LCD) {
bit = 0; /* LCDENABLE /
}
else {
bit = 1; /
DIGITALENABLE */
}

/* if the channel is not enabled, we don’t need GO */
if (REG_GET(DISPC_CONTROL, bit, bit) == 0) {
goto end;
}

if (channel == OMAP_DSS_CHANNEL_LCD) {
bit = 5; /* GOLCD /
}
else {
bit = 6; /
GODIGIT */
}
*********************** CODE END ***********************

Appreciate any help in this regard.

Regards,
Kiran Murari
