From 3704e7784d0f65d926901799af14247613006876 Mon Sep 17 00:00:00 2001 From: Alistair Popple Date: Thu, 15 Jun 2017 15:51:54 +1000 Subject: NPU2: Add flag to nvlink config space indicating DL reset state Device drivers need to be able to determine if the DL is out of reset or not so they can safely probe to see if links have already been trained. This patch adds a flag to the vendor specific config space indicating if the DL is out of reset.
