From 3abc7cff671a15f797f2baca9ba6b406508757b8 Mon Sep 17 00:00:00 2001 From: "Lendacky, Thomas" Date: Wed, 28 Jun 2017 13:41:49 -0500 Subject: [PATCH] amd-xgbe: Use the proper register during PTP initialization During PTP initialization, the Timestamp Control register should be cleared and not the Tx Configuration register. While this typo causes the wrong register to be cleared, the default value of each register and and the fact that the Tx Configuration register is programmed afterwards doesn't result in a bug, hence only fixing in net-next.
