From 19df7510d5cf077c2e88a7690fb7617e6d341beb Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Mon, 21 Jan 2019 18:41:42 +0800 Subject: ptp: add debugfs support for ptp_qoriq This patch is to add debugfs support for ptp_qoriq. Current debugfs supports to control fiper1/fiper2 loopback mode. If the loopback mode is enabled, the fiper1/fiper2 pulse is looped back into trigger1/ trigger2 input. This is very useful for validating hardware and driver without external hardware. Below is an example to enable fiper1 loopback. echo 1 > /sys/kernel/debug/2d10e00.ptp_clock/fiper1-loopback Signed-off-by: Yangbo Lu Signed-off-by: David S.
