This particular constant was named with prefix "CCS881", which should be "CCS811" instead, just like the rest of constant names in the file, as this driver implementation is for AMS CCS811 sensor. "CCS881" could literally be referring to another sensor product unrelated to AMS CCS811 sensor. Signed-off-by:

The old code was based on a DHT11 datasheet which specifies a measurement range of 20%-90% RH. Turns out the sensor actually reports values outside this range, so we should support it as far as possible. Reported-by:

iio_dev->mlock is to be used only by the IIO core for protecting device mode changes between INDIO_DIRECT and INDIO_BUFFER. This patch replaces the use of mlock with the already established buf_lock mutex. Introducing 'unlocked' forms of read and write registers. The read/write frequency functions now require buf_lock to be held. That's not obvious so avoid this but moving the locking inside the functions where it is then clear that they are taking the unlocked forms of the register read/write. It isn't readily apparent that write frequency function requires the locks to be taken, so move it inside the function to where it is required to protect. Also, the read raw does not require iio_dev->mlock for reads. It can run concurrently as resource protection is handled by buf_lock in read register. Signed-off-by:

There is no option to perform 64bit integer sqrt on 32bit platform. Added stronger typed int_sqrt64 enables the 64bit calculations to be performed on 32bit platforms. Using same algorithm as int_sqrt() with strong typing provides enough precision also on 32bit platforms, but it sacrifices some performance. In case values are smaller than ULONG_MAX the standard int_sqrt is used for calculation to maximize the performance due to more native calculations. Signed-off-by:

Drivers should not 'select' a subsystem. Instead they should depend on it. If the subsystem is disabled, the user probably did that for a purpose and one driver shouldn't be changing that. This also makes all IIO drivers consistent w.r.t depending on SYSFS instead of selecting it. Signed-off-by:

The X-Powers AXP813 PMIC is really close to what is already done for AXP20X/AXP22X. There are two pairs of bits to set the rate (one for Voltage and Current measurements and one for TS/GPIO0 voltage measurements) instead of one. The register to set the ADC rates is different from the one for AXP20X/AXP22X. GPIO0 can be used as an ADC (measuring Volts) unlike for AXP22X. The scales to apply to the different inputs are unlike the ones from AXP20X and AXP22X. Signed-off-by:

To prepare for a future patch that will add a DT node for the ADC, make axp20x_adc able to probe from DT and get the per-variant data from of_device_id.data since platform_device_id.driver_data won't be set when probing by DT. Leave the ability to probe via platform for driver compatibility with old DTs. Signed-off-by:

The burnout currents can be enabled only if buffer is enabled and CHOP is disabled. So, if neither of these conditions are met, then we should disable the burnout currents in the driver as well, and warn the user. This change doesn't fix anything. The burnout currents simply won't work if CHOP is enabled or buffer is disabled. The intent is to provide the user with some feedback instead of silently not working inside the chip. Signed-off-by:

This patch changes the indentation of the statements after case labels. The linux coding guidelines do not explicitly mentiond this but pretty much all existing code doesn't put any statements into the same line of their belonging case labels. Therefore this adapts to the more usual style. Please note that there is still a lot of > 80 character lines which will cause checkpatch warnings. This patch does not intent to fix this already existing issue. Signed-off-by:

Several staging directories have TODO files that indicate a subsystem will be removed in the future. Using a status entry of "S: Obsolete" helps indicate the subsystem files should not be modified unnecessarily. checkpatch also tests this setting and emits a warning that the matching subsystem files should not be modified. This might help avoid receiving patches that will be dropped. Signed-off-by:
