Overlay update is required for resolving the missing symbol errors, so marking the PR as draft temporarily.

Awesome!!!! i'll merge it right now..

[RobertCNelson]

@vaishnav98 please use this branch for the "overlay" (src/arm/overlay) update: https://github.com/beagleboard/BeagleBoard-DeviceTrees/tree/v5.14.x it'll get pulled directly into this tree..

https://github.com/beagleboard/BeagleBoard-DeviceTrees/tree/v5.14.x/src/arm/overlays

aka kernel specific overlays...

Regards,

Thank you @RobertCNelson , Sure I will use beagleboard/BeagleBoard-DeviceTrees/tree/v5.14.x for the overlay update
