Unable to Boot the custom Hardware for imx8mm mini

[msharma]

Hello all,

           We have designed a custom hardware by the reference of imx8mm mini. All the hardware configurations are same, we have just removed some peripherals not required. It is rebooting again and again while loading the kernel.

    I have disabled all nodes associated with the DSI, as I don't need it. Still getting error associated with display.          

Following are my kernel logs :

Please check your USB hardware and dts in uboot ,as the log reports that "dev_get_parent_plat: null device"

Thanks for your reply,
                      The issue is resolved by disabling CONFIG_USB_TCPC in  imx8mm_evk_defconfig file.
