watchdog: Add support for WDIOC_GETTIMELEFT IOCTL in watchdog core

2012-03-27T18:15:37+00:00

This patch adds support for WDIOC_GETTIMELEFT IOCTL in watchdog core. So, there
is another function pointer added to struct watchdog_ops, which can be passed by
drivers to support this IOCTL.

Related documentation is updated too.

watchdog: watchdog_dev: Let the driver update the timeout field on set_timeout success

2012-03-27T18:07:43+00:00

When a set_timeout operation succeeds this does not necessarily mean that
the exact timeout requested has been achieved, because the watchdog does not
necessarily have a 1 second resolution. So rather then have the core set
the timeout member of the watchdog_device struct to the exact requested
value, instead the driver should set it to the actually achieved timeout value.

watchdog: documentation: remove index-file

2012-03-27T17:57:26+00:00

The 00-index file in the watchdog directory is, like many others,
outdated (conversion-howto is missing) and doesn't contain worthwhile
additional information. As it seems to be a maintenance burden without
much gain, simply remove it.

watchdog: add nowayout helpers to Watchdog Timer Driver Kernel API

2012-01-06T14:22:04+00:00

Add two nowayout helpers for the Watchdog Timer Driver Kernel API.
And apply this to the already converted drivers.
Note: s3c2410_wdt lost the nowayout feature during the conversion.

watchdog: WatchDog Timer Driver Core - Add minimum and max timeout

2011-07-28T08:01:18+00:00

Add min_timeout (minimum timeout) and max_timeout
values so that the framework can check if the new
timeout value is between the minimum and maximum
timeout values. If both values are 0, then the
framework will leave the check for the watchdog
device driver itself.

watchdog: WatchDog Timer Driver Core - Add ioctl call

2011-07-28T08:01:16+00:00

Add support for extra ioctl calls by adding a
ioctl watchdog operation. This operation will be
called before we do our own handling of ioctl
commands. This way we can override the internal
ioctl command handling and we can also add
extra ioctl commands. The ioctl watchdog operation
should return the appropriate error codes or
-ENOIOCTLCMD if the ioctl command should be handled
through the internal ioctl handling of the framework.
