If on watchdog device registration a parent device is not set, then the registered watchdog is considered to be a virtual device:
/sys/devices/virtual/watchdog/watchdog0 /sys/devices/virtual/watchdog/watchdog1 Setting a correct reference to a platform device allows to distinguish multiple instances of iMX2+ hardware watchdogs: /sys/devices/soc0/soc/2000000.aips-bus/20bc000.wdog/watchdog/watchdog0 /sys/devices/soc0/soc/2000000.aips-bus/20c0000.wdog/watchdog/watchdog1 Signed-off-by: Vladimir Zapolskiy <[email protected]> --- drivers/watchdog/imx2_wdt.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/watchdog/imx2_wdt.c b/drivers/watchdog/imx2_wdt.c index 5e6d808..3450a46 100644 --- a/drivers/watchdog/imx2_wdt.c +++ b/drivers/watchdog/imx2_wdt.c @@ -256,6 +256,7 @@ static int __init imx2_wdt_probe(struct platform_device *pdev) wdog->ops = &imx2_wdt_ops; wdog->min_timeout = 1; wdog->max_timeout = IMX2_WDT_MAX_TIME; + wdog->parent = &pdev->dev; clk_prepare_enable(wdev->clk); -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
