* watchdog: xilinx_wwdt: Add Versal window watchdog supportSrinivas Neeli2023-06-261-0/+18
| | | | | | | | | | | | | | | | Versal watchdog driver uses window watchdog mode. Window watchdog timer(WWDT) contains closed(first) and open(second) window with 32 bit width. Write to the watchdog timer within predefined window periods of time. This means a period that is not too soon and a period that is not too late. The WWDT has to be restarted within the open window time. If software tries to restart WWDT outside of the open window time period, it generates a reset.

| * watchdog: mt7621-wdt: avoid ralink architecture dependent codeSergio Paracuellos2023-03-021-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MT7621 SoC has a system controller node. Watchdog need to access to reset status register. Ralink architecture and related driver are old and from the beggining they are using some architecture dependent operations for accessing this shared registers through 'asm/mach-ralink/ralink_regs.h' header file. However this is not ideal from a driver perspective which can just access to the system controller registers in an arch independent way using regmap syscon APIs. Update Kconfig accordingly to select new added dependencies and allow driver to be compile tested.

| * watchdog/pseries-wdt: initial support for H_WATCHDOG-based watchdog timersScott Cheloha2022-07-201-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PAPR v2.12 defines a new hypercall, H_WATCHDOG. The hypercall permits guest control of one or more virtual watchdog timers. The timers have millisecond granularity. The guest is terminated when a timer expires. This patch adds a watchdog driver for these timers, "pseries-wdt". pseries_wdt_probe() currently assumes the existence of only one platform device and always assigns it watchdogNumber 1. If we ever expose more than one timer to userspace we will need to devise a way to assign a distinct watchdogNumber to each platform device at device registration time.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MAX77714 is a MFD chip whose watchdog has the same programming procedures as the MAX77620 watchdog, but most register offsets and bit masks are different, as well as some features. Support the MAX77714 watchdog by adding a variant description table holding the differences. All the features implemented by this driver are available on the MAX77714 except for the lack of a WDTOFFC bit. Instead of using a "HAS_*" flag we handle this by holding in the cnfg_glbl2_cfg_bits struct field the bits (i.e. the features) to enable in the CNFG_GLBL2 register. These bits differ among the two models. This implementation allows to avoid any conditional code, keeping the execution flow unchanged.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Realtek MIPS SoCs (platform name Otto) have a watchdog timer with pretimeout notifitication support. The WDT can (partially) hard reset, or soft reset the SoC. This driver implements all features as described in the devicetree binding, except the phase2 interrupt, and also functions as a restart handler. The cpu reset mode is considered to be a "warm" restart, since this mode does not reset all peripherals. Being an embedded system though, the "cpu" and "software" modes will still cause the bootloader to run on restart. It is not known how a forced system reset can be disabled on the supported platforms. This means that the phase2 interrupt will only fire at the same time as reset, so implementing phase2 is of little use.

| * watchdog: Remove BCM63XX_WDTFlorian Fainelli2021-12-281-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we can utilize the BCM7038_WDT driver, remove that one which was not converted to the watchdog APIs. There are a couple of notable differences with how the bcm7038_wdt driver proceeds: - bcm63xx_wdt would register with the ad-hoc BCM63xx hardware timer API, but this would only be used in order to catch the interrupt *before* a SoC reset and make the kernel "die" - bcm6xx_wdt would register a software timer and kick it every second in order to pet the watchdog, thus offering a two step watchdog process. This is not something that is brought over to the bcm7038_wdt as it is deemed unnecessary. If user-space cannot pet the watchdog, but a kernel timer can, the system is still in a bad shape anyway. bcm7038_wdt is simpler in its behavior and behaves as a standard watchdog driver and is not making use of any specific platform APIs, therefore making it more maintainable and extensible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This rewrites the IXP4xx watchdog driver as follows: - Spawn the watchdog driver as a platform device from the timer driver. It's one device in the hardware, and the fact that Linux splits the handling into two different devices is a Linux pecularity, and thus it becomes a Linux pecularity to spawn a separate watchdog driver. - Spawn the watchdog driver from the timer driver at probe(). This is well after the timer driver as actually registered and started and we know the register base is available. - Instead of looping back callbacks to the timer drivers for all watchdog calls, pass the register base to the watchdog driver and manage the registers there. The two drivers aren't even interested in the same register so the spinlock is totally surplus, delete it. - Replace pretty much all of the content in the watchdog driver with a simple, modern watchdog driver utilizing the watchdog core instead of registering its own misc device and ioctl() handling. - Drop module parameters as the same already exist in the watchdog core. What remains is a slim elegant (IMO) watchdog driver using the watchdog core, spawning from device tree or boardfile alike.

* watchdog: Add hrtimer-based pretimeout featureCurtis Klein2021-06-211-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the option to use a hrtimer to generate a watchdog pretimeout event for hardware watchdogs that do not natively support watchdog pretimeouts. With this enabled, all watchdogs will appear to have pretimeout support in userspace. If no pretimeout value is set, there will be no change in the watchdog's behavior. If a pretimeout value is set for a specific watchdog that does not have built-in pretimeout support, a timer will be started that should fire at the specified time before the watchdog timeout would occur. When the watchdog is successfully pinged, the timer will be restarted. If the timer is allowed to fire it will generate a pretimeout event. However because a software timer is used, it may not be able to fire in every circumstance. If the watchdog does support a pretimeout natively, that functionality will be used instead of the hrtimer. The general design of this feaure was inspired by the software watchdog, specifically its own pretimeout implementation. However the software watchdog and this feature are completely independent. They can be used together; with or without CONFIG_SOFT_WATCHDOG_PRETIMEOUT enabled. The main advantage of using the hrtimer pretimeout with a hardware watchdog, compared to running the software watchdog with a hardware watchdog, is that if the hardware watchdog driver is unable to ping the watchdog (e.g. due to a bus or communication error), then the hrtimer pretimeout would still fire whereas the software watchdog would not.

| | | | | | | | | | | | | | Commit 92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support") removed the last selector of CONFIG_MV64X60. Therefore CONFIG_MV64X60_WDT cannot be selected anymore and can be removed.

| | | | | | | | | | | | | Add Watchdog support for ROHM BD9576MUF and BD9573MUF PMICs which are mainly used to power the R-Car series processors. The watchdog is pinged using a GPIO and enabled using another GPIO. Additionally watchdog time-out can be configured to HW prior starting the watchdog. Watchdog timeout can be configured to detect only delayed ping or in a window mode where also too fast pings are detected.
