Dear NXP team,
We have designed our custom product based on imx8mq SoC and we are good with the things nowadays.
We want to detect HDMI at u-boot level. How can it be done ?
On our imx6 base product we are already using it and we have usecase for this and in imx6 u-boot
struct display_info_t structure in board file have
.detect = hdmi_detect
but in imx8mq u-boot it is NULL. And hence u-boot is always default to HDMI irrespective of HDMI monitor is connected or not.
Please advise how to achieve our usecase of detecting HDMI at uboot level.

Hitesh
Hi Hitesh
some hdmi related codes are provided in uboot:
imx8mq_evk.c\imx8mq_evk\freescale\board - uboot-imx - i.MX U-Boot
edid detection codes can be reused from linux sources, one can look
at sect.6.4.6 High-Definition Multimedia Interface (HDMI) and Display
Port (DP) Overview attached Linux Manual.
Best regards
igor
