There is no need to flush fifo and loose all data when the iio buffer is full. Just drop the data by ignoring the error as commonly done in other drivers. Signed-off-by:

According to the latest datasheet, LSM6DSM and LSM6DSL imu sensors export GENMASK(10, 0) for FIFO threshold mask definition. Despite that is not an actual issue since write on fifo_th register is protected by max_fifo_size value, fix fifo_th and fifo_diff register definitions Fixes: 290a6ce1 ("iio: imu: add support to lsm6dsx driver") Signed-off-by:

The events IIO_EV_INFO_VALUE and IIO_EV_INFO_ENABLE currently have a falling and rising direction configured. There does not need to be a separate distinction so this patch changes these to use the either direction.

The hardware supports 16-bit ALS and proximity readings, however the datasheet recommends using the I2C auto increment protocol so that the correct high and low bytes are read even if the integration cycle ends between reading the lower and upper registers. Signed-off-by:

The struct tsl2x7x_settings contained a persistence member that contained both the ALS and proximity persistence fields. This patch splits this out into two separate fields so that the bitmasks in several parts of the code are no longer necessary. The default persistence settings are also changed by this patch from: - Proximity: 0 (Every proximity cycle generates an interrupt) - ALS: 255 (60 consecutive values out of range) to something a little more reasonable based on my testing: - Proximity: 1 (1 proximity value out of range) - ALS: 1 (1 value outside of threshold range) Signed-off-by:

The struct tsl2x7x_settings contained an interrupts_en member that was a bitmask for which interrupts are enabled. This required having bitmasks in several parts of the code. This patch splits this field out into two booleans to remove most of the bitmasks in the code. This patch also fixes a bug where if an interrupt pin was configured, but proximity interrupts were disabled, then the proximity value could not be polled. This patch also removes an unnecessary second call to writing the control register in tsl2x7x_chip_on(). Driver tested using a TSL2772 hooked up to a Raspberry Pi 2. Signed-off-by:

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.

tsl2x7x_get_lux() does not need to clear the interrupt flag when querying the ALS. The interrupt flag is cleared in tsl2x7x_event_handler(). This patches removes the unnecessary code. Signed-off-by:

Brian Masney authored
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: thresh, direction: either ...

As a follow up to the work in commit a0722d05 ("staging: iio: tsl2x7x: convert mutex_trylock() to mutex_lock()"), this patch removes the unnecessary calls to tsl2x7x_get_prox() and tsl2x7x_get_lux() in tsl2x7x_event_handler(). Previously, these functions were locked with mutex_trylock(), but that is no longer the case. This patch also removes a comment that is no longer relevant about returning the last sample.

The original code had a read function per data size; after updates, all read functions tasks were centralized in a single function, but the old signature was kept to maintain the module working without problems. This patch removes a set of duplications associated with read_reg_*, and update the areas that calling the old interface by the new one. Signed-off-by:

The read operation for the I2C function has many duplications that can be generalized into a single function. This patch reworks the read operation for I2C to centralizes all similar code in a single function. It is possible to remove all the old interface to use the new one, however, for keeping the things simple and working this patch maintain legacy interface. Signed-off-by:
