[PATCH] ARM: stm32: Ping IWDG on exit from PSCI suspend code

2024-04-19 Thread Marek Vasut
Make sure the OS would not get any spurious IWDG pretimeout IRQ right after the system wakes up. This may happen in case the SoC got woken up by another source than the IWDG pretimeout and the pretimeout IRQ arrived immediately afterward, but too late to be handled by the suspend main loop. In case
