Arvind Yadav 68c82befe4 watchdog: ziirave: constify i2c_device_id
i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

Enric Balletbo i Serra 217209db02 watchdog: ziirave_wdt: Add support to upload the firmware.
This patch adds and entry to the sysfs to start firmware upload process
on the specified device with the requested firmware.

The uploading of the firmware needs only to happen once per firmware
upgrade, as the firmware is stored in persistent storage. If the
firmware upload or the firmware verification fails then we print and
error message and exit.

Enric Balletbo i Serra 22daf7a716 watchdog: ziirave_wdt: Correct I2C device id to fix module autoloading.
The I2C core removes the manufacturer prefix from the compatible field
so it reports to user-space the uevent i2c:rave-wdt, but this doesn't
match with the i2c_device_id (i2c:ziirave-wdt) array so the module is not
autoloaded. Correct the I2C device id to match with the reported uevent
and fix the module autoloading functionality.

Martyn Welch 0ce72f3544 watchdog: ziirave_wdt: Rename "trigger" reset reason "hw watchdog"
The Zodiac watchdog is implemented on a microcontoller. The reset reason
currently labelled "trigger" is not to detect when the watchdog has
triggered (as had been initially understood and suggested by the naming),
but to inform the reader that the watchdog, which in fact has it's own
hardware watchdog, has been reset because the hardware watchdog has
triggered. Renaming to "hw watchdog".
