[PATCH] drivers: video: hdmi: log ext colorimetry applicability

[Johan Korsnes]

When logging the AVI InfoFrame, clearly indicate whether or not the
extended colorimetry attribute is active. This is only the case when
the AVI InfoFrame colorimetry attribute is set to extended. [0]

Yeah, seems fine. Might make the logs a bit less confusing at least.

I was actually going to deal with the ACE bits as part of this patch,
but noticed that things seem to be hard coded for AVI InfoFrame v2:

int hdmi_avi_infoframe_init(struct hdmi_avi_infoframe *frame) {
    memset(frame, 0, sizeof(*frame));
 
    frame->type = HDMI_INFOFRAME_TYPE_AVI;
    frame->version = 2;
    frame->length = HDMI_AVI_INFOFRAME_SIZE;

    return 0;
}

I have no plans to fix this, for now, unfortunately.

If we tackle this, then it would be part of a larger effort in updating
this code. There are more fields missing in other InfoFrames as well.

So yes, we have interest in this, but no, there are no plans :-)

I just realized that there are more fields like that:

content_type is only valid if itc == true

quantization_range is only valid if colorspace is RGB

ycc_quantization_range is only valid if colorspace is YCC

Can you make a v2 where these fields are handled in the same way?
That would really help reduce the confusion when logging the
AVI InfoFrame.
