Hello,
I'm trying to read 10 bit BT656 using an omap3 DM3730 (omap3-isp).
The bt565 data comes from ADV7842 configured manually from i2c, I have
checked the ADV configuration using an evaluation board
(EVAL-ADV7842-7511P) in BT656 10 bits mode. Then I assume that the
10bit BT656 arrives to the omap isp.
In the kernel side, I use a tvp5150 driver like a dummy driver in
order to configure the MC and V4L2, this dummy driver only have
patched the i2c read/write and is well registered.
My question is about 10bit instead of 8 bits of tvp5150, in the
omap3-isp driver the 10 bits for BT656 is not configured (the
ISPCCDC_CFG_BW656 is not set in ispccdc.c file)
I just added
isp_reg_set(isp, OMAP3_ISP_IOMEM_CCDC, ISPCCDC_CFG, ISPCCDC_CFG_BW656);
inside of ccdc_set_stream function, and I have checked that the bit 5
in 0x480B_C654 CCDC_CFG omap register and comes to "1"
But with yavta I can't capture the image sent from ADV7842, after
convert with raw2rgbpnm appear the "image", attached link.

Any clue about how to use BT656 10 bits in omap3 (DM3730)?
I have tested with kernel v4.5 mainline and v4.3 that was used for
validate the tvp5150(bt656 8bit) video captures to omap3-isp.
Best Regards
Eduard Gavin
