Disabling color space conversion on the ADV7619 for deep color

I would like some assistance on the following issue we are having on the

ADV7619 HDMI receiver.

For our usage, we would like to disable the color space conversion block when

receiving deep color.  In other words, we would like to verify that the 36 bits

we’re receiving are from the TMDS without any change of value.  We’ve found

that for non-deep color cases, we can set OP_FORMAT_SEL = 0x54 or 0x96 in the

ADV7619 with some success, but if the connected source sends an odd number of

active pixels, or sends deep color, this solution isn’t optimal.

In short, we would really like to use OP_FORMAT_SEL = 0x42 or 0x82 but not have

the colors modified by the Rx chip.  Are there any settings that can get us

there?
