2017-09-09watchdog: ziirave: constify i2c_device_idArvind Yadav1-1/+1
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.

2016-09-23watchdog: ziirave_wdt: Add support to upload the firmware.Enric Balletbo i Serra1-5/+404
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.

2016-07-17watchdog: ziirave_wdt: Correct I2C device id to fix module autoloading.Enric Balletbo i Serra1-1/+1
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.

2016-03-01watchdog: ziirave_wdt: Rename "trigger" reset reason "hw watchdog"Martyn Welch1-1/+1
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". Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
