watchdog: add gpio watchdog driver

2021-08-31T10:04:03+00:00

A rather common kind of external watchdog circuit is one that is kept alive by toggling a gpio. Add a driver for handling such a watchdog. The corresponding linux driver apparently has support for some watchdog circuits which can be disabled by tri-stating the gpio, but I have never actually encountered such a chip in the wild; the whole point of adding an external watchdog is usually that it is not in any way under software control. For forward-compatibility, and to make DT describe the hardware, the current driver only supports devices that have the always-running property. I went a little back and forth on whether I should fail ->probe or only ->start, and ended up deciding ->start was the right place. The compatible string is probably a little odd as it has nothing to do with linux per se - however, I chose that to make .dts snippets reusable between device trees used with U-Boot and linux, and this is the (only) compatible string that linux' corresponding driver and DT binding accepts. I have asked whether one should/could add "wdt-gpio" to that binding, but the answer was no: https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/ If someone feels strongly about this, I can certainly remove the "linux," part from the string - it probably wouldn't the only place where one can't reuse a DT snippet as-is between linux and U-Boot.

watchdog: Add support for K3 RTI watchdog

2020-08-11T04:48:27+00:00

This is based on the Linux kernel driver for the RTI watchdog. To actually reset the system on an AM65x, it requires firmware running on the R5 that accepts the NMI and issues the actual system reset via TISCI. Kind of an iTCO, except that this watchdog hardware has support for no-way-out, and only for that. On the J721E, reset works without extra firmware help when routing the RTI interrupt via the ESM.

Watchdog: introduce ARM SBSA watchdog driver

2020-07-27T08:54:15+00:00

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 In the single stage mode, when the timeout is reached, your system will be reset by WS1. The first signal (WS0) is ignored. Signed-off-by: Zhao Qiang Signed-off-by: Biwen Li Reviewed-by: Stefan Roese Reviewed-by: Priyanka Jain
