2011-07-28watchdog: WatchDog Timer Driver Core - Add minimum and max timeoutWim Van Sebroeck
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.

2011-07-28watchdog: WatchDog Timer Driver Core - Add ioctl callWim Van Sebroeck
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.

2011-07-28watchdog: WatchDog Timer Driver Core - Add basic frameworkWim Van Sebroeck
The WatchDog Timer Driver Core is a framework that contains the common code for all watchdog-driver's. It also introduces a watchdog device structure and the operations that go with it. This is the introduction of this framework. This part supports the minimal watchdog userspace API (or with other words: the functionality to use /dev/watchdog's open, release and write functionality as defined in the simplest watchdog API). Extra functionality will follow in the next set of patches.

2011-07-28arm/versatile: Add device tree supportGrant Likely
For testing the dt work, define a dt-enabled versatile platform. This patch adds a new versatile platform for when using the device tree. Add platform and amba devices are discovered and registered by parsing the device tree. Clocks and initial io mappings are still configured statically. This patch still depends on some static platform_data for a few devices which is passed via the auxdata structure to of_platform_populate(), but it is a viable starting point until the drivers can get all configuration data out of the device tree.

2011-07-28hwmon: (coretemp) Add core/pkg threshold support to CoretempDurgadoss R
This patch adds the core and pkg support to coretemp. These thresholds can be configured via the sysfs interfaces tempX_max and tempX_max_hyst. An interrupt is generated when CPU temperature reaches or crosses above tempX_max OR drops below tempX_max_hyst.

Add support for NTC Thermistor series. In this release, the following thermistors are supported: NCP15WB473, NCP18WB473, NCP03WB473, and NCP15WL333. This driver is based on the datasheet of MURATA. The driver in the patch does conversion from the raw ADC value (either voltage or resistence) to temperature. In order to use voltage values as input, the circuit schematics should be provided with the platform data. A compensation table for each type of thermistor is provided for the conversion.
