Just paste my current pieces of codes here:
static struct db8500_thsens_platform_data* db8500_thermal_parse_dt(struct platform_device *pdev) {
if (!np) { dev_err(&pdev->dev, "Missing device tree data\n");
}
static int db8500_thermal_probe(struct platform_device *pdev) {
ptrips = db8500_thermal_parse_dt(pdev); if (!ptrips) ptrips = dev_get_platdata(&pdev->dev);
So, the above code still has the flaw i pointed out. It will print "Missing device tree data", while booting for non-DT case.
What i would suggest you is:
static int db8500_thermal_probe(struct platform_device *pdev) { struct device_node *np = pdev->dev.of_node;
if (np) ptrips = db8500_thermal_parse_dt(pdev); else ptrips = dev_get_platdata(&pdev->dev);
if (!ptrips) explode!!
ret = devm_request_threaded_irq(&pdev->dev, low_irq, NULL,
I just saw that all the PRCMU and ab8500 related irqs use request_threaded_irq only difference is that I use devm_request_threaded_irq
See, i started this threaded_irq thread is to make sure you know exactly what you are doing. Others are doing it doesn't mean you should do it too.. :)
You must dig in a bit to see why is it required for your case? If earlier code related to PRCMU and db8500 is correct, then i am sure you need to sleep from your handler.
