2016-03-16Watchdog: introduce ARM SBSA watchdog driverFu Wei
According to Server Base System Architecture (SBSA) specification, the SBSA Generic Watchdog has two stage timeouts: the first signal (WS0) is for alerting the system by interrupt, the second one (WS1) is a real hardware reset. More details about the hardware specification of this device: ARM DEN0029B - Server Base System Architecture (SBSA) This driver can operate ARM SBSA Generic Watchdog as a single stage watchdog or a two stages watchdog, it's set up by the module parameter "action". In the single stage mode, when the timeout is reached, your system will be reset by WS1. The first signal (WS0) is ignored. In the two stages mode, when the timeout is reached, the first signal (WS0) will trigger panic. If the system is getting into trouble and cannot be reset by panic or restart properly by the kdump kernel(if supported), then the second stage (as long as the first stage) will be reached, system will be reset by WS1. This function can help administrator to backup the system context info by panic console output or kdump. This driver bases on linux kernel watchdog framework, so it can get timeout from module parameter and FDT at the driver init stage.

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 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.
