The iio_device lock is only meant for internal use. Hence define a device local lock to protect against concurrent accesses. While at it, properly include "mutex.h" for mutex related APIs. Signed-off-by:

In order to drop the internal lock usage we needed two different things: 1) The first place where 'mlock' was being used was a typical case where iio_device_claim_direct_mode() fits perfectly. 2) In the second case, it was being used to prevent concurrent accesses to the device and shared data but nothing was being enforced with regards to buffering (i.e, there was nothing preventing from changing the conversion mode while buffering). Hence, in this case, a new lock was introduced in the state structure. Note that the goal is not to introduce any functional change and that is the reason why a new lock was introduced to guarantee 2). While at it, properly include "mutex.h" for mutex related APIs.

This is a precursor change to make it simpler to remove the 'mlock' usage. Having the code in it's own helper function, also makes it easier to read the error paths. Signed-off-by:

'mlock' was being grabbed when setting the device frequency. In order to not introduce any functional change a new lock is added. With that in mind, the lock also needs to be grabbed in the places where 'mlock' is since it was also being used to protect st->config against the current device state. On the other places the lock was being used, we can just drop it since we are only doing one i2c bus read/write which is already safe. While at it, properly include "mutex.h" for mutex related APIs.

In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs. It's more simple in error path. Signed-off-by:

As the vcnl4040 and vcnl4200 chip uses runtime power management for turning the ambient light and proximity sensors on/off, it overwrites the entire register each time. In ALS_CONF register bit fields ALS_IT, ALS_PERS, ALS_INT_EN are overwritten. In PS_CONF1 register bit fields PS_DUTY, PS_PERS, PS_IT, PS_HD, and PS_INT are overwritten. Add functions for preserving the affected bit fields when changing power state. Signed-off-by:

ADMV8818_SW_IN_WR0_MSK and ADMV8818_SW_OUT_WR0_MSK have 3 bits, which means a length of 8, but freq_range_hpf and freq_range_lpf array size is 4, may end up reading 4 elements beyond the end of those arrays. Check value first before access freq_range_hpf and freq_range_lpf to harden against the hardware allowing out of range values. Signed-off-by:

The current EINVAL value is more applicable to embedded library, where user can actually put the fixed value to the sensor. In case of the driver if the value of the channel is invalid it is better in inform userspace that Channel was out of range as that implies more to internal driver error than invalid input. It also makes for easier debugging of where the error comes from during the development. Signed-off-by:

Allow users to read sensor sampling frequency to better plan the application measurement requests. Signed-off-by:

Crt Mori authored
The sensor can operate in lower power modes and even make measurements when in those lower powered modes. The decision was taken that if measurement is not requested within 2 seconds the sensor will remain in SLEEP_STEP power mode, where measurements are triggered on request with setting the start of measurement bit (SOB). In this mode the measurements are taking a bit longer because we need to start it and complete it. Currently, in continuous mode we read ready data and this mode is activated if sensor measurement is requested within 2 seconds. The suspend timeout is increased to 6 seconds (instead of 3 before), because that enables more measurements in lower power mode (SLEEP_STEP), with the lowest refresh rate (2 seconds). Signed-off-by:

Drop 'mlock' usage by making use of iio_device_claim_direct_mode(). This change actually makes sure we cannot do a single conversion while buffering is enable. Note there was a potential race in the previous code since we were only acquiring the lock after checking if the bus is enabled.
