Subject: [PATCH 02/11] staging: iio: tsl2x7x: correct interrupt handler trigger
Date: Wed, 21 Mar 2018 06:29:03 -0400 [thread overview]
Message-ID: <20180321102912.5130-3-masneyb@onstation.org> (raw)
In-Reply-To: <20180321102912.5130-1-masneyb@onstation.org>
tsl2x7x_event_handler() was not called as expected when the device was
asserting a hardware interrupt. This patch changes the interrupt line
trigger from rising to falling.
The driver was tested on a TSL2772 hooked up to a Raspberry Pi 2. The
interrupt pin also had a 10K pull-up resistor per the requirements from
the datasheet. The relevant device tree binding:
&i2c1 {
tsl2772@39 {
compatible = "amstaos,tsl2772";
reg = <0x39>;
interrupt-parent = <&gpio>;
interrupts = <22 0x2>;
};
};
With this patch, iio_event_monitor now shows the events when the
channels are outside the defined interrupt thresholds.
$ sudo ./iio_event_monitor tsl2772
Found IIO device with name tsl2772 with device number 0
Event: time: 1478193460053760446, type: proximity, channel: 0, evtype:

...
