2015-12-28watchdog: ts4800: add driver for TS-4800 watchdogDamien Riegel
This watchdog is instantiated in a FPGA that is memory mapped. It is made of only one register, called the feed register. Writing to this register will re-arm the watchdog for a given time (and enable it if it was disable). It can be disabled by writing a special value into it. It is part of a syscon block, and the watchdog register offset in this block varies from board to board. This offset is passed in the syscon property after the phandle to the syscon node.

2015-09-09watchdog: add a driver to support SAMA5D4 watchdog timerWenyou Yang
From SAMA5D4, the watchdog timer is upgrated with a new feature, which is describled as in the datasheet, "WDT_MR can be written until a LOCKMR command is issued in WDT_CR". That is to say, as long as the bootstrap and u-boot don't issue a LOCKMR command, WDT_MR can be written more than once in the driver. So the SAMA5D4 watchdog driver's implementation is different from the at91sam9260 watchdog driver implemented in file at91sam9_wdt.c. The user application open the device file to enable the watchdog timer hardware, and close to disable it, and set the watchdog timer timeout by seting WDV and WDD fields of WDT_MR register, and ping the watchdog by issuing WDRSTT command to WDT_CR register with hard-coded key.

This commit adds support for the watchdog timer found in NXP LPC SoCs family, which includes LPC18xx/LPC43xx. Other SoCs in that family may share the same watchdog hardware. Watchdog driver registers a restart handler that will restart the system by performing an incorrect feed after ensuring the watchdog is enabled in reset mode. As watchdog cannot be disabled in hardware, driver's stop routine will regularly send a keepalive ping using a timer.

2015-06-22watchdog: digicolor: driver for Conexant Digicolor CX92755 SoCBaruch Siach
This commit add a driver for the watchdog functionality of the Conexant CX92755 SoC, from the Digicolor series of SoCs. Of 8 system timers provided by the CX92755, the first one, timer A, can reset the chip when its counter reaches zero. This driver uses this capability to provide userspace with a standard watchdog, using the watchdog timer driver core framework. This driver also implements a reboot handler for the reboot(2) system call. The watchdog driver shares the timer registers with the CX92755 timer driver (drivers/clocksource/timer-digicolor.c). The timer driver, however, uses only timers other than A, so both drivers should coexist.

2014-06-10s390/watchdog: add support for LPAR operation (diag288)Philipp Hachtmann
Add the LPAR variant of the diag 288 watchdog to the driver. The only available action on timeout for LPAR is a PSW restart. Signed-off-by: Philipp Hachtmann <phacht@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

A large chunk of this are clock drivers (bcm281xx, exynos, versatile, shmobile), aside from that, reset controllers for STi as well as a large rework of the Marvell Orion/EBU watchdog driver are notable" * tag 'drivers-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (99 commits) Revert "dts: socfpga: Add DTS entry for adding the stmmac glue layer for stmmac."

2014-03-31watchdog: Fix Elan SC520 dependenciesJean Delvare
Anyone using a system based on an AMD Elan SC520 processor would be building a dedicated kernel for it, so we can make the sc520_wdt driver depend on MELAN. SC520_CPUFREQ already depends on MELAN so it makes things more consistent. It also makes kernel configuration for every other x86 user easier.
