Subject[PATCH v2 0/2] watchdog: report all watchdog_ident information via sysfs
This synchronizes the information reported by ioctl and sysfs.
The mismatch is confusing because "wdctl" from util-linux uses the ioctl
when used with root privileges and sysfs without.

Userspace implementation:

To: Wim Van Sebroeck <>
To: Guenter Roeck <>
Signed-off-by: Thomas Weißschuh <>

Changes in v2:
- Report options in addition to firmware_version
- Add documentation
- Rename firmware_version to fw_version to avoid conflicts
- Link to v1:

Thomas Weißschuh (2):
watchdog: report fw_version in sysfs
watchdog: report options in sysfs
