On AP side we have 500ms delay between checks. To avoid timing issues, reduce delay between checks and raise total # of checks so that overall time for sequence is the same. Testing Done: - Used for DB3.5/EVT1.5 hardware during bringup - Regression tested on DB3.1+ES2, DB3.1+ES3 Signed-off-by: Michael Scott Reviewed-by: Vaibhav Hiremath Tested-by: Vaibhav Hiremath Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/staging/greybus/arche-platform.c b/drivers/staging/greybus/arche-platform.c index f18cec6..65c8f71 100644 --- a/drivers/staging/greybus/arche-platform.c +++ b/drivers/staging/greybus/arche-platform.c @@ -52,7 +52,7 @@ static void svc_delayed_work(struct work_struct *work) container_of(work, struct arche_platform_drvdata, delayed_work.work); struct device *dev = arche_pdata->dev; struct device_node *np = dev->of_node; - int timeout = 10; + int timeout = 50; int ret; /* @@ -74,7 +74,7 @@ static void svc_delayed_work(struct work_struct *work) if (gpio_get_value(arche_pdata->wake_detect_gpio) == 0) break; - msleep(500); + msleep(100); } while(timeout--); if (timeout >= 0) {
