2015-09-09watchdog: NXP LPC18xx Watchdog Timer DriverAriel D'Alessandro
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: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

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.

2014-06-10watchdog: iop_wdt only builds for mach-iop13xxArnd Bergmann
All three iop variants we support in Linux (iop32x, iop33x and iop13xx) seem to have support for the watchdog hardware, but this driver fails to build for the first two of these because it uses the IOP13XX_WDTCR_IB_RESET macro that is only defined for iop13xx. This clarifies the dependency in Kconfig to avoid randconfig build errors. It is unlikely that anyone will ever miss support for this driver on the ancient iop3xx platforms, so we don't need to bother trying to fix it properly.
