staging: iio: tsl2x7x: rename driver to tsl2772

2018-05-12T11:24:29+00:00

This patch renames this driver from tsl2x7x to tsl2772 since it is
highly likely that additional devices will be added to this driver that
do not match that wildcard. The tsl2772 driver name was selected since
that is currently the device with the most features that are supported
by this driver.

This patch also adds Brian Masney's copyright to tsl2772.h for all of
the work that has been done to move this driver out of staging.

staging: iio: tsl2x7x: add range checking to tsl2x7x_write_raw

2018-05-12T11:23:06+00:00

The CALIBBIAS and INT_TIME masks in tsl2x7x_write_raw did not have any
range checking in place so this patch adds the appropriate range
checking. The defines TSL2X7X_ALS_GAIN_TRIM_{MIN,MAX} are also
introduced by this patch.

staging: iio: tsl2x7x: correct IIO_EV_INFO_PERIOD values

2018-05-12T11:21:27+00:00

The thresh periods assumed an integration time of 3ms. This patch adds
support for the correct integration time (2.72ms or 2.73ms). The code
had the ALS filter values as going up to 15, however the values actually
went up to 60 since the values scaled in increments of 5 once the
persistence value went above 3.

staging: iio: tsl2x7x: convert to use read_avail

2018-05-12T11:19:27+00:00

Make the sysfs attributes in_proximity0_calibscale_available, and
in_intensity0_{calibscale,integration_time}_available be created
using info_mask_separate_available on the channel configuration.

The driver assumed that the ALS increment was 2.72 ms, and the upper
range was 696 ms. Some other supported devices use 2.73 ms - 699 ms.
This patch adds support for the multiple ranges.

staging: iio: tsl2x7x: use macro to populate tsl2X7X_device_info

2018-05-12T11:17:49+00:00

This patch creates a macro that populates the tsl2X7X_device_info
structure to reduce duplicated code in the driver.

staging: iio: tsl2x7x: turn chip off if IIO device registration fails

2018-05-12T11:16:39+00:00

This patch turns the chip off if IIO device registration fails so that
the error handling mirrors the device remove to make review easier in
preparation for moving this driver out of staging.

This patch also adds a missing error check in the call to
tsl2x7x_chip_on() in tsl2x7x_probe().

staging: iio: tsl2x7x: use direct returns

2018-05-12T11:15:47+00:00

This patch changes the functions tsl2x7x_read_event_value() and
tsl2x7x_read_raw() to use direct returns to simplify the code.

staging: iio: tsl2x7x: add device ids for code readability

2018-05-06T18:25:21+00:00

This patch adds the device IDs to the device_channel_config array to
improve code readability.
