How about having these one per line, with a description: - compatible: should contain one of: * "ti,palmas-usb-vid" for palmas systems. * "ti,twl6035-usb-vid" for twl6035 systems. * "ti,palmas-usb" (DEPRECATED - use "ti,palmas-usb-vid"). * "ti,twl6035-usb" (DEPRECATED - use "ti,twl6035-usb-vid"). That makes it easier to add to in future, and hopefully makes things a bit clearer. I don't think we need to state it's kept for backwards compatiblity. The set of strings Linux understands is a Linux detail rather than a dt detail. > > Optional Properties: > - ti,wakeup : To enable the wakeup comparator in probe > diff --git a/drivers/extcon/extcon-palmas.c b/drivers/extcon/extcon-palmas.c > index 6c91976..6e83e9a 100644 > --- a/drivers/extcon/extcon-palmas.c > +++ b/drivers/extcon/extcon-palmas.c > @@ -269,7 +269,9 @@ static const struct dev_pm_ops palmas_pm_ops = { > > static struct of_device_id of_palmas_match_tbl[] = { > { .compatible = "ti,palmas-usb", }, > + { .compatible = "ti,palmas-usb-vid", }, > { .compatible = "ti,twl6035-usb", }, > + { .compatible = "ti,twl6035-usb-vid", }, It might be worth a /* DEPRECATED */ note on the old strings. Otherwise, the looks sensible to me. Thanks, Mark.
