tsl2x7x_prox_cal() would set the interrupt flag, and reset the device to start doing the calibration routine. However, this did not actually affect the readings since they are polled. This patch drops the interrupt code. This patch also drops the function tsl2x7x_prox_calculate() and removes support for the standard deviation and min sample since those values were not used. Driver was tested using a TSL2772 hooked up to a Raspberry Pi 2. I performed the following testing at various distances: - Put hand in front of sensor and keep the sensor and hand stationary. - Perform calibration routine. - Run iio_event_monitor. - Verify that a proximity event is triggered when my hand comes anywhere between the sensor and where I performed the calibration routine.

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.
