HI there,
I am trying to use the gpio driver for pca953x with IRQ enabled config. When
the device gets probbed, I gives me an error saying :
"failed to set trigger mode 8"
The probe called,
ret = devm_request_threaded_irq(&client->dev,
client->irq,
NULL,
pca953x_irq_handler,
IRQF_TRIGGER_LOW | IRQF_ONESHOT,
dev_name(&client->dev), chip);
with IRQF_TRIGGER_LOW as a flag
I did some tracing and found out, irq set type, went to gic_set_type in irq-
gic.c ( http://lxr.free-electrons.com/source/drivers/irqchip/irq-gic.c#L187 )
But gic_set_type, only wants to see either IRQF_TRIGGER_HIGH OR
IRQF_TRIGGER_LOW, thats why it returned.
Questions
1. Is it correct that irq set type went to gic_set_type, bcoz pca953x does
provide one of itself.
