| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver currently uses a CPU family match of 17h to determine EFCH_PM_DECODEEN_WDT_TMREN register support. This family check will not support future AMD CPUs and instead will require driver updates to add support. Remove the family 17h family check and add a check for SMBus PCI revision ID 0x51 or greater. The MMIO access method has been available since at least SMBus controllers using PCI revision 0x51. This revision check will support family 17h and future AMD processors including EFCH functionality without requiring driver changes.

| * watchdog: imx2_wdg: Alow ping on suspendAlistair Francis2022-03-271-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i.MX watchdog cannot be disabled by software once it has been enabled. This means that it can't be stopped before suspend. For systems that enter low power mode this is fine, as the watchdog will be automatically stopped by hardware in low power mode. Not all i.MX platforms support low power mode in the mainline kernel. For example the i.MX7D does not enter low power mode and so will be rebooted 2 minutes after entering sleep states. This patch introduces a device tree property "fsl,ping-during-suspend" that can be used to enable ping on suspend support for these systems.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Provide necessary infrastructure to support that case: - use source clock's rate for all timer related calculations - use bus clock to gate/ungate the register interface All devices that use the single clock are kept intact: if only one clock is passed from Device Tree, it will be used for both purposes as before.

| * watchdog: db8500_wdt: Rename driverLinus Walleij2021-11-013-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | This driver is named after the ambition to support more SoCs than the DB8500. Those were never produced, so cut down the scope and rename the driver accordingly. Since the Kconfig for the watchdog defaults to y this will still be built by default.
