Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by:

Add support for CCS811 VOC sensor. This patch adds support for reading current and voltage across the sensor and TVOC and equivalent CO2 values. Scale and offset values have been computed according to datasheet: - For current: raw value is in microamps => 0.001 scale to convert to milliamps - For voltage: 1.65V = 1023, therefore 1650mV = 1023 => 1650.0/1023 = 1.612903 scale to convert to millivolts - For eCO2: raw value range is from 400ppm to 8192ppm. => (val - 400) * (100 - 0) / (8192 - 400) + 0 = (val - 400) * 0.01283367 => offset: -400, scale = 0.012834 to get a percentage value -For TVOC: raw value range is from 0ppb to 1187ppb. => (val - 0) * 100 / (1187 - 0) + 0 = val * 0.0842459 => scale = 0.084246 for getting a percentage value Cc: Daniel Baluta <daniel.baluta@gmail.com> Cc: Alison Schofield <amsfield22@gmail.com> Signed-off-by:Narcisa Ana Maria Vasile <narcisaanamaria12@gmail.com> Signed-off-by:

Drop static on a local variable, when the variable is initialized before any possible use. Thus, the static has no benefit. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> Signed-off-by:

When adding maps to the list, they were added using list_add, which adds them in LIFO order. When parsing using iio_channel_get_all(), these elements are hence returned in reverse order. As a result, the iio_hwmon mapping maps the first entry to the last channel and so on. Signed-off-by:

The return value from tsl2x7x_invoke_change() was not checked in most places in the driver. This patch adds the proper error checks. The return values inside tsl2x7x_invoke_change() are now checked by this patch as well. Previously, if there was an error turning the chip back on, then the driver would attempt to turn the chip off and incorrectly return success. The code to power off the chip is removed by this patch since we should fail fast. Signed-off-by:

This driver in some cases can busy wait for upwards of 15ms. Since the kernel at this point is not running in atomic context, and is running in process context, we can safely use usleep_range() instead. This patch changes the two occurrences of mdelay() to usleep_range(). Signed-off-by:

tsl2x7x_read_thresh() and tsl2x7x_write_thresh() currently assumes that IIO_EV_INFO_VALUE is the only iio_event_info that will be passed in. This patch refactors these two functions so that additional iio_event_infos can be passed in. The functions are renamed from tsl2x7x_{read,write}_thresh() to tsl2x7x_{read,write}_event_value(). This patch also adds the missing return value check to tsl2x7x_invoke_change() since this was previously missing. This patch is in preparation for moving the in_intensity0_thresh_period and in_proximity0_thresh_period sysfs attributes to be created by iio_event_spec. Signed-off-by: -

The calibration function calls i2c_smbus_write_byte() and i2c_smbus_read_byte(). These two function calls are replaced with a single call to i2c_smbus_read_byte_data() by this patch. This patch also removes an unnecessary call that reads the CNTRL register a second time. One of the error paths returned -1 if the ADC was not enabled and this patch changes that return value to -EINVAL. Signed-off-by:

tsl2x7x_i2c_read() would call i2c_smbus_write_byte() and i2c_smbus_read_byte(). These two i2c functions can be replaced with a single call to i2c_smbus_read_byte_data(). This patch removes the tsl2x7x_i2c_read() function and replaces all occurrences with a call to i2c_smbus_read_byte_data(). Signed-off-by:
