* watchdog: drop owner assignment from platform_driversWolfram Sang2014-10-201-1/+0
| | | | | | | A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* watchdog: kempld-wdt: Use the correct value when configuring the prescaler ↵gundberg2014-06-101-1/+1
| | | | | | | | | | | | | | with the watchdog Use the prescaler index, rather than its value, to configure the watchdog. This will prevent a mismatch with the prescaler used to calculate the cycles.

* watchdog: Drop unnecessary include of miscdevice.hGuenter Roeck2013-12-101-1/+0
| | | | | | | | | | 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. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: Get rid of MODULE_ALIAS_MISCDEV statementsJean Delvare2013-11-171-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | STAGE_CFG bits are defined as [5:4] bits. However, '(((x) & 0x30) << 4)' handles [9:8] bits. Thus, it should be fixed in order to handle [5:4] bits.
