This adds a debugfs entry to view the current status of the ptp registers. Signed-off-by: Phil Reid <preid-qgqNFa1JUf/o2iN0hyhwsIdd74u8MsAO@public.gmane.org>Your description should explain what this is good for. Why do you need to look at this through debugfs?Happy to drop this one. I found it helpful when debugging the ptp behaviour. Allowing quick access to monitor the register updates by the ptp driver. Is there an alternative method that is preferred?
For tracing what the driver does, I'd add a trace event, which also lets you see when any updates happen.
