Here is a reference in "Crystal Mirror", Vol 7, Dharma Publishing that partly addresses the question:
The remaining texts in the Prajanaparamita section of the bKa'-'gyur comprises the Paritta collection, works from the Pali tradition recited for blessing and protection.
These sutras are (listing only the titles):
WOW! #35 Maitri-bhavana sutra (or at least a version of it) is included! Chills went up my spine. Then there are several well-known Pali suttas mentioned.
At the Pali correspondence site I mentioned there are several references to texts from the Digha Nikaya in particular that are included in the Kangyur (or at least exist in Tibetan). Digha Nikaya 1 for example.
Several of these can probably be linked to their presumed Pali equivalent (like the Mangala Sutta, Suriya Sutta). Others are very familiar but I can't locate them just now (Panacasiksanusamsa-sutra, Mahakasyapa-sutra). Dharmacakra-pravartana-sutra is the Dharma-Chakra Pravartana Sutta and this is the First Turning of the Wheel.
