The i.MX watchdog hardware supports programmable - timeouts ranging from 0.5 to 128 seconds, in half-second increments. Once - activated, the watchdog hardware cannot be deactivated, but the timeout - period can be changed to any valid non-zero value.</p> -<p class="Pp">At power-on, a special 16-second ‘power-down timer’ - mode is automatically enabled by the hardware. It will assert the external - WDOG_B signal, which may be connected to external hardware that causes the - system to reset or power-down. The power-down timer is often reset by the - boot loader (typically U-Boot). If the power-down timer is still active at - the time when the normal watchdog is first enabled, the - <code class="Nm">imx_wdog</code> driver automatically disables it.</p> -<p class="Pp">The <code class="Nm">imx_wdog</code> driver supports the FDT - <var class="Va">fsl,external-reset</var> property by enabling the assertion - of the WDOG_B external timeout signal when the property is present. When - running this way, the need to reset the system due to watchdog timeout is - signaled by driving the WDOG_B line low; some external entity is expected to - assert the chip's POR pin in response. The <code class="Nm">imx_wdog</code> - driver attempts to backstop this external reset by scheduling an interrupt - to occur as well. The interrupt handler waits 1 second for the external - reset to occur, then it triggers a normal software reset. Note that the - WDOG_B signal can be configured to use a variety of pins on the chip. For - the <var class="Va">fsl,external-reset</var> property to be effective, the - signal must be connected to an appropriate pin by the system's FDT pinctrl - data.</p> -<p class="Pp">The <code class="Nm">imx_wdog</code> driver supports the FDT - <var class="Va">timeout-secs</var> property by enabling the watchdog as soon - as the driver attaches, using the given timeout value.
