iio: tsl2x7x/tsl2772: avoid potential division by zero

2018-06-24T13:22:38+00:00

It may be possible for tsl2772_get_lux to return a zero lux value and hence a division by zero can occur when lux_val is zero. Check for this case and return -ERANGE to avoid the division by zero.

iio: tsl2583: correct values in integration_time_available

2018-05-20T09:29:28+00:00

The times reported by the in_illuminance_integration_time_available sysfs attribute are actually in milliseconds, not microseconds. This patch corrects the times with the correct unit. The fixes tag is inaccurate as the issue existed when the driver was still in staging. However, lots of changes occured before it graduated so this is as a good a point as any for backports.

iio: Replace occurrences of magic number 0 by IIO_CHAN_INFO_RAW

2018-03-07T20:14:36+00:00

Usually, functions responsible for reading raw data typically relies on values from iio_chan_info_enum to correctly identify the type of data to be read. There is a set of a device driver that uses the magic number 0 instead of IIO_CHAN_INFO_RAW. This patch improves the readability by replaces the magic number 0 for the appropriate IIO_CHAN_INFO_RAW in six devices driver in the IIO subsystem.

iio: cros_ec: Relax sampling frequency before suspending

2018-03-03T15:02:58+00:00

If an application set a tight sampling frequency, given the interrupt use is a wakeup source, suspend will not happen: the kernel will receive a wake up interrupt and will cancel the suspend process. Given cros_ec sensors type is non wake up, this patch adds prepare and complete callbacks to set 1s sampling period just before suspend. This ensures the sensor hub will not be a source of interrupt during the suspend process.

iio: light: make a couple of config structures static

2018-01-08T15:03:41+00:00

Structures st_uvis25_i2c_regmap_config and st_uvis25_spi_regmap_config are local to the source and do not need to be in global scope, so make them both static. Cleans up sparse warnings: warning: symbol 'st_uvis25_i2c_regmap_config' was not declared. Should it be static? warning: symbol 'st_uvis25_spi_regmap_config' was not declared. Should it be static?
