watchdog: qcom: stop watchdog by default

2026-03-24T10:51:52Z

Prevent the Qualcomm watchdog from autostarting and ensure it's stopped when the driver probed. In some cases the watchdog is left running by a previous bootloader stage. Disable autostart so it isn't left running when we boot into the OS, this behaviour can be changed by enabling autostart in the board defconfig.

watchdog: qcom: Add max timeout check to prevent overflow

2026-01-14T15:17:48Z

Added a check to ensure the requested timeout does not exceed the hardware's maximum supported value. This prevents register overflow and ensures watchdog reliability. So, added a check in qcom_wdt_start() to ensure the requested timeout does not exceed the hardware-supported maximum value. If the requested value exceeds the maximum value, then the timeout is clamped at maximum value. The timeout is first converted to watchdog ticks and then compared against QCOM_WDT_MAX_TIMEOUT. This helps prevent misconfiguration and potential watchdog misbehavior due to overflow. QCOM_WDT_MAX_TIMEOUT is set to 0xFFFFF, as Qualcomm SoCs typically use 20 bits to store bark/bite timeout values.
