Blindly copying platform data behaviour to DT bindings is seldom a good idea. > Signed-off-by: Marek Vasut <marex@xxxxxxx> > Cc: Lee Jones <lee.jones@xxxxxxxxxx> > Cc: Linus Walleij <linus.walleij@xxxxxxxxxx> > Cc: Samuel Ortiz <sameo@xxxxxxxxxxxxxxx> > Cc: Vipul Kumar Samar <vipulkumar.samar@xxxxxx> > Cc: Viresh Kumar <viresh.kumar@xxxxxxxxxx> > --- > drivers/mfd/stmpe.c | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/drivers/mfd/stmpe.c b/drivers/mfd/stmpe.c > index 4b11202..fb9cd6f 100644 > --- a/drivers/mfd/stmpe.c > +++ b/drivers/mfd/stmpe.c > @@ -1018,6 +1018,11 @@ void stmpe_of_probe(struct stmpe_platform_data *pdata, struct device_node *np) > pdata->id = -1; > pdata->irq_trigger = IRQF_TRIGGER_NONE; > > + pdata->irq_over_gpio = of_get_property(np, "irq-over-gpio", NULL); This is a new DT binding and you haven't provided any documentation for it.
