Refer to HDMI 1.4 section 6.5.3, non-zero CD data GCP should send in deep color mode. Now, when HDMI work in 24bpp, it will send non-zero CD(0x4 for 24bit) data GCP to protocol analyzer. It means current HDMI source is working in “24bit deep color mode”. But HDMI 1.4 CTS 7-19 required DUT should in “No Deep Color support”. Protocol analyzer expect received zero CD GCP or no GCP. Disable GCP when bpp is 24 to pass CTS 7-19. Signed-off-by: Sandor Yu <Sandor.yu@nxp.com>
