2019-05-05watchdog: ux500_wdt: Convert to use device managed functions and other ↵Guenter Roeck
improvements Use device managed functions to simplify error handling, reduce source code size, improve readability, and reduce the likelyhood of bugs. Other improvements as listed below. The conversion was done automatically with coccinelle using the following semantic patches. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches - Drop empty remove function - Introduce local variable 'struct device *dev' and use it instead of dereferencing it repeatedly - Use devm_watchdog_register_driver() to register watchdog device Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@linux-watchdog.org>
2015-09-09Watchdog: Fix parent of watchdog_devicesPratyush Anand
/sys/class/watchdog/watchdogn/device/modalias can help to identify the driver/module for a given watchdog node. However, many wdt devices do not set their parent and so, we do not see an entry for device in sysfs for such devices. This patch fixes parent of watchdog_device so that /sys/class/watchdog/watchdogn/device is populated. Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not have any parent. Not sure, how we can identify driver for these devices.

2013-12-10watchdog: Drop unnecessary include of miscdevice.hGuenter Roeck
After commit 487722cf2 (watchdog: Get rid of MODULE_ALIAS_MISCDEV statements) the affected drivers no longer need to include miscdevice.h. Only exception is rt2880_wdt.c which never needed it.

2013-11-17watchdog: Get rid of MODULE_ALIAS_MISCDEV statementsJean Delvare
I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR) and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements. Either the device is enumerated and the driver already has a module alias (e.g. PCI, USB etc.) that will get the right driver loaded automatically. Or the device is not enumerated and loading its driver will lead to more or less intrusive hardware poking. Such hardware poking should be limited to a bare minimum, so the user should really decide which drivers should be tried and in what order. Trying them all in arbitrary order can't do any good. On top of that, loading that many drivers at once bloats the kernel log. Also many drivers will stay loaded afterward, bloating the output of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets loaded as a dependency) can't even be unloaded! If defining char-major-10-130 is needed then it should happen in user-space.
