I think this patch should be merged with doc changes:
- almost all in patch 2 with driver code
- the dpdk-devbind.py chapter in patch 3

Almost yes.
The doc part about dpdk-devbind.py should be in patch 3.

+OCTEON TX2 REE Regexdev Driver
+===============================
+
+The OCTEON TX2 REE PMD (**librte_pmd_octeontx2_regex**) provides poll mode
