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.
