+       For ADAS parts by default Display is disabled in linux via
+       k3-<soc>-vision-apps.dtso and enabled to be controlled by one of the
+       real time r5f core. So modetest, kmstest, weston will not work.
+       To enabled it you need to modify k3-<soc>-vision-apps.dtso, rebuild
+       linux-dtbs and install. Also need to disable Display in r5f, rebuild
+       r5f FW using PSDK RTOS.
