2020-03-08iio: imu: adis: add unlocked __adis_initial_startup()Alexandru Ardelean
This change splits the __adis_initial_startup() away from adis_initial_startup(). The unlocked version can be used in certain calls during probe, where races won't happen since the ADIS driver may not be registered yet with IIO.

This change overrides commit 380b107bbf944 ("iio: adis: Introduce timeouts structure"). It removes the memory allocation and moves the 'adis_data' information to be static on the chip_info struct. This also adds a timeout structure to ADIS16334, since it was initially omitted. This was omitted (by accident) when the change was done.

2020-03-08iio: light: vcnl4000: update sampling periods for vcnl4040Tomas Novotny
Vishay has published a new version of "Designing the VCNL4200 Into an Application" application note in October 2019. The new version specifies that there is +-20% of part to part tolerance. Although the application note is related to vcnl4200, according to support the vcnl4040's "ASIC is quite similar to that one for the VCNL4200". So update the sampling periods (and comment), including the correct sampling period for proximity. Both sampling periods are lower. Users relying on the blocking behaviour of reading will get proximity measurements much earlier.

Vishay has published a new version of "Designing the VCNL4200 Into an Application" application note in October 2019. The new version specifies that there is +-20% of part to part tolerance. This explains the drift seen during experiments. The proximity pulse width is also changed from 32us to 30us. According to the support, the tolerance also applies to ambient light. So update the sampling periods. As the reading is blocking, current users may notice slightly longer response time.

At the moment, reading from in_magn_*_raw in sysfs tends to return large values around 65000, even though the output of ak8974 is actually limited to ±32768.

2020-02-14iio: light: Add a driver for Sharp GP2AP002x00FLinus Walleij
This driver handles two different Sharp sensors that have been proposed for merging to the mainline kernel over the years, and already has a limited proximity-only driver in the input subsystem. These components are completely different from the confusingly similarly named Sharp GP2AP020A00F, for which we have a driver in drivers/iio/light/gp2ap020a00f.c The two components GP2AP002A00F and GP2AP002S00F are distinctively different but similar: they share the same set of registers but differ slightly in the I2C protocol. Instead of the approach by the previous input driver, we create a combined IIO proximity and light sensor driver. The plan is to merge this driver and delete the input driver. The pieces for the driver are picked all over the place after researching and grepping through a few different vendor trees and driver submissions. We merge it under the light sensors because: - It has similarities with the Capella CM3605 light sensor and proximity driver which is there. - It is related to the GP2AP020A00F driver which is also there. This driver was tested with the Samsung GT-S7710 mobile phone which has the GP2AP002S00F proximity sensor mounted. The suspend/resume cycle will disable the interrupt from the sensor. If someone would desire to use this interrupt for wakeup, the driver will need modifications.
