[dpdk-dev] [PATCH v2 23/30] net/dpaa2: add dprtc sub-module

[Sachin Saxena <sachin.saxena@nxp.com>]

From: Priyanka Jain <priyanka.jain@nxp.com>

This patch add support for dprtc
(Data Path Real Time Clock) sub-module
based on MC 10.16.0 flib.

It provides interface for PTP stack software
to access physical IEEE 1588 Real Time Clock.
