This needs to below template. Changed as following
+* **Updated Marvell cnxk eventdev driver.**
+
+ * Added support for ``remaining_ticks_get`` timer adapter PMD callback
+ to get the remaining ticks to expire for a given event timer.
+
Changed subject as event/cnxk: support get remaining ticks callback
Applied to dpdk-next-net-eventdev/for-main. Thanks
