2012-09-24hwmon: (sch56xx-common) Fix build warningsGuenter Roeck1-14/+14
Fix: warning: 'address' may be used uninitialized in this function warning: 'name' may be used uninitialized in this function While those are false warnings, the patch reduces module size on x86_64 by approximately 110 bytes, so it is still worth the effort.

2012-05-30watchdog: sch56xx-common: set correct bits in register()Dan Carpenter1-2/+2
WDOG_NO_WAY_OUT (3) and WDOG_ACTIVE (0) are the bit numbers, not a mask. So "data->wddev.status |= WDOG_ACTIVE;" was intended to set bit zero but it is a no-op.

2012-05-30watchdog: sch56xx-common: Add proper ref-counting of watchdog dataHans de Goede1-1/+29
This fixes referencing free-ed memory in the corner case where /dev/watchdog is open when the platform driver gets unbound from the platform device. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2012-05-30watchdog: sch56xx: Remove unnecessary checks for register changesHans de Goede1-25/+16
Since the watchdog core keeps track of the watchdog's active state, start/stop will never get called when no changes are necessary. So we can remove the check for the output_enable register changing before writing it (which is an expensive operation).

2012-05-30watchdog: sch56xx: Use watchdog coreHans de Goede1-313/+58
Convert sch56xx drivers to the generic watchdog core. Note this patch depends on the "watchdog: Add multiple device support" patch from Alan Cox. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
2012-03-20hwmon: (sch56xx) Add support for the integrated watchdog (v2)Hans de Goede1-2/+517
Add support for the watchdog integrated into the SMSC SCH5627 and SCH5636 superio-s. Since the watchdog is part of the hwmon logical device and thus shares ioports with it, the watchdog driver is integrated into the existing hwmon drivers for these. Note that this version of the watchdog support for sch56xx superio-s implements the watchdog chardev interface itself, rather then relying on the recently added watchdog core / watchdog_dev. This is done because currently some needed functionality is missing from watchdog_dev, as soon as this functionality is added (which is being discussed on the linux-watchdog mailinglist), I'll convert this driver over to using watchdog_dev.

2011-07-25hwmon: New driver sch5636Hans de Goede1-0/+4
This patch adds a new driver for SMSC SCH5636 Super I/O chips. The chips include an embedded microcontroller for hardware monitoring solutions, allowing motherboard manufacturers to create their own custom hwmon solution based upon the SCH5636. Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based hwmon solution. The sch5636 driver runs a sanity check on loading to ensure it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based hwmon solution.

2011-07-25hwmon: (sch5627) Factor out some code shared with sch5636 driverHans de Goede1-0/+336
This patch adds a new sch56xx-common.ko which contains code which will also be used in the new sch5636 driver. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
