Hi,
I posted a query here (https://lkml.org/lkml/2015/8/10/19), but did not get any
feedback. So, thought to post patches and to seek response.
I need some way to identify the driver/module for a given watchdog node say
/dev/watchdog0.
Documentation/watchdog/watchdog-api.txt says:
identity a string identifying the watchdog driver
However, all the watchdog driver does not define identity as DRV_NAME.
Otherway could be to look for /sys/class/watchdog/watchdog0/device/modalias.
However, many wdt devices does not set its parent and so, we do not see an entry
for /sys/class/watchdog/watchdog0/device/ in sysfs.
This patch set fixes parent for wdt drivers written in watchdog-core framework.
Exceptions: booke, diag288, mpc8xxx, octeon, softdog and w83627hf -- They do not
have any parent. Not sure, how we can identify driver for these devices.
Series makes sense, but imposes a huge burden on the maintainer.
I think this is one of those changes where a single patch would make much more
sense.
I merged all patches into my test repository for build and runtime tests,
but I would suggest to resubmit the series as a single patch.
Thanks,
Guenter
