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

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
