iio: adc: ti-ads1015: avoid getting stale result after runtime resume
This driver assumes that the device is operating in the continuous
conversion mode which performs the conversion continuously. So this driver
doesn't insert a wait time before reading the conversion register if the
configuration is not changed from a previous request.
This assumption is broken if the device is runtime suspended and entered
a power-down state. The forthcoming request causes reading a stale result
from the conversion register as the device is runtime resumed just before.
Fix it by adding a flag to detect that condition and insert a necessary
wait time.

iio: adc: ti-ads1015: enable conversion when CONFIG_PM is not set
The ADS1015 device have two operating modes, continuous conversion mode
and single-shot mode. This driver assumes that the continuous conversion
mode is selected by runtime resume callback when the ADC result is
requested.
If CONFIG_PM is disabled, the device is always in the default single-shot
mode and no one begins a single conversion. So the conversion register
doesn't contain valid ADC result. Fix it by changing the continuous mode
in probe function.

The ti-ads1015 driver supports ADS1015 and ADS1115 devices. The same
scale information is used for both devices in this driver, however they
have actually different values and the ADS1115's one is not correct.
These devices have the same full-scale input voltage range for each PGA
selection. So instead of adding another hardcoded scale information,
compute a correct scale on demand from each device's resolution.

iio: adc: ti-ads1015: fix incorrect data rate setting update
The ti-ads1015 driver has eight iio voltage channels and each iio channel
can hold own sampling frequency information.
The ADS1015 device only have a single config register which contains an
input multiplexer selection, PGA and data rate settings. So the driver
should load the correct settings when the input multiplexer selection is
changed.
However, regardless of which channlel is currently selected, changing any
iio channel's sampling frequency information immediately overwrites the
current data rate setting in the config register.
It breaks the current data rate setting if the different channel's sampling
frequency information is changed because the data rate setting is not
reloaded when the input multiplexer is switched.
This removes the unexpected config register update and correctly load the
data rate setting before getting adc result.

Jonathan writes:
First round of IIO new device support, features and cleanups for the 4.14 cycle.
4 completely new drivers in this set and plenty of other stuff.
One ABI change due to a silly mistake a long time back. Hopefully no
one will notice. It effects the numerical order of consumer device
channels which was the reverse of the obvious. It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)
New Device Support
* ccs811
- new driver for the Volatile Organic Compounds (VOC) sensor.
* dln2 adc
- new driver for the ADC on this flexible usb board.
* EP93xx
- new driver for this Cirrus logic SoC ADC.
* ltc2471
- new ADC driver support the ltc2471 and ltc2473
* st_accel
- add trivial table entries to support H3LIS331DL, LIS331DL, LIS3LV02DL.
* st_gyro
- add L3GD20H support (again) having fixed the various things that were
broken in the first try. Includes devicetree binding.
* stm32 dac
- add support for the DACs in the STM32F4 series
Features
* Documentation
- add missing power attribute documentation to the ABI docs.
* at91-sama5d2
- add hardware trigger and buffered capture support with bindings.
- suspend and resume functionality.
* bmc150
- support for the BOSC0200 ACPI device id seen on some tablets.
* hdc100x
- devicetree bindings
- document supported devices
- match table and device ids.
* hts221
- support active low interrupts (with bindings)
- open drain mode with bindings.
* htu21
- OF match table and bindings.
* lsm6dsx
- open drain mode with bindings
* ltc2497
- add support for board file based consumer mapping.
* ms5367
- OF match table and bindings.
* mt7622
- binding document and OF match table.
- suspend and resume support.
* rpr0521
- triggered buffer support.
* tsys01
- OF match table and bindings.
Cleanups and minor fixes
* core
- fix ordering of IIO channels to entry numbers when using
iio_map_array_register rather than reversing them.
- use the new %pOF format specifier rather than full name for the
device tree nodes.
*
ad7280a
- fix potential issue with macro argument reuse.
* ad7766
- drop a pointless NULL value check as it's done in the gpiod code.
* adis16400
- unsigned -> unsigned int.
* at91 adc
- make some init data static to reduce code size.
* at91-sama5d2 ADC
- make some init data static to reduce code size.
* da311
- make some init data static to reduce code size.
* hid-sensor-rotation
- drop an unnecessary static.
* hts221
- refactor the write_with_mask code.
- move the BDU configuration to probe time as there is no reason for it
to change.
- avoid overwriting reserved data during power-down. This is a fix, but
the infrastructure need was too invasive to send it to mainline except
in a merge window. It's not a regression as it was always wrong.
- avoid reconfigure the sampling frequency multiple times by just
doing it in the write_raw function directly.
- refactor the power_on/off calls into a set_enable.
- move the dry-enable logic into trig_set_state as that is the only
place it was used.
* ina219
- fix polling of ina226 conversion ready flag.
* imx7d
- add vendor name in kconfig for consistency with similar parts.
* mcp3422
- Change initial channel to 0 as it feels more logical.
- Check for some errors in probe.
* meson-saradc
- add a check of of_match_device return value.
* mpu3050
- allow open drain for any interrupt type.
* rockchip adc
- add check on of_match_device return value.
* sca3000
- drop a trailing whitespace.
* stm32 adc
- make array stm32h7_adc_ckmodes_spec static.
* stm32 dac
- fix an error message.
* stm32 timers
- fix clock name in docs to match reality after changes.
* st_accel
- explicit OF table (spi).
- add missing entries to OF table (i2c).
- rename of_device_id table to drop the part name.
- adding missing lis3l02dq entry to bindings.
- rename H3LIS331DL_DRIVER_NAME to line up with similar entries in driver.
* st_gyro
- explicit OF table (spi).
* st_magn
- explicit OF table (spi).
- enable multiread for lis3mdl.
* st_pressure
- explicit OF table (spi).
* st_sensors common.
- move st_sensors_of_i2c_probe and rename to make it available for spi
drivers.
* tsc3472
- don't write an extra byte when writing the ATIME register.
- add a link to the datasheet.
* tsl2x7x - continued staging cleanups
- add of_match_table.
- drop redundant power_state sysfs attribute.
- drop wrapper tsl2x7x_i2c_read.
- clean up i2c calls made in tsl2x7x_als_calibrate.
- refactor the read and write _event_value callbacks to handle additional
elements.
- use usleep_range instead of mdelay.
- check return value from tsl2x7x_invoke_change.
* zpa2326
- add some newline to the end of logging macros.

- there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all

xen/balloon: don't online new memory initially
When setting up the Xenstore watch for the memory target size the new
watch will fire at once. Don't try to reach the configured target size
by onlining new memory in this case, as the current memory size will
be smaller in almost all cases due to e.g. BIOS reserved pages.
Onlining new memory will lead to more problems e.g. undesired conflicts
with NVMe devices meant to be operated as block devices.
Instead remember the difference between target size and current size
when the watch fires for the first time and apply it to any further
size changes, too.
In order to avoid races between balloon.c and xen-balloon.c init calls
do the xen-balloon.c initialization from balloon.c.

iio: chemical: ccs811: Add support for AMS CCS811 VOC sensor
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
