The file name 70 is the hardware dependent pin name. Reading from this 71 file produces two numbers, the assigned function (see 72 the PTP_PF_ enumeration values in linux/ptp_clock.h) 73 and the channel number. The function and channel 74 assignment may be changed by two writing numbers into 75 the file. 76 | 1What: /sys/class/ptp/ 2Date: September 2010 3Contact: Richard Cochran <richardcochran@gmail.com> 4Description: 5 This directory contains files and directories 6 providing a standardized interface to the ancillary 7 features of PTP hardware clocks. 8 --- 60 unchanged lines hidden (view full) --- 69 pin offered by the PTP hardware clock.

Reading 83 "1" means that the PPS is supported, while "0" means 84 not supported. 85 --- 37 unchanged lines hidden --- | 78Date: September 2010 79Contact: Richard Cochran <richardcochran@gmail.com> 80Description: 81 This file indicates whether the PTP hardware clock 82 supports a Pulse Per Second to the host CPU.
