DP firmware for imx8mq

Hello,

I'm using meta-freescale for my custom board and I have an issue with
DisplayPort. I've flashed imx-boot with dp signed firmware + added dts
changes but during boot I see in log:

dmesg | grep dp
[ 0.095997] No USDPAA memory, no 'fsl,usdpaa-mem' in device-tree

I'm using the dunfell release. Do I need to use some other firmware or
am I missing something? My CPU is imx8mq.

Thanks and BR,
