From c78275f366c687b5b3ead3d99fc96d1f02d38a8e Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Fri, 22 Apr 2011 12:03:54 +0200 Subject: ptp: Added a clock that uses the eTSEC found on the MPC85xx. The eTSEC includes a PTP clock with quite a few features. This patch adds support for the basic clock adjustment functions, plus two external time stamps, one alarm, and the PPS callback.
