From de46584675fad02b7f8255f31be0ea1be5cd185b Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Sat, 22 Sep 2012 07:02:04 +0000 Subject: ptp: clarify the clock_name sysfs attribute There has been some confusion among PHC driver authors about the intended purpose of the clock_name attribute. This patch expands the documation in order to clarify how the clock_name field should be understood. Signed-off-by: Richard Cochran Signed-off-by: David S.
