The stm32-timer-cnt driver doesn't use the iio interface. The iio headers aren't relevant and can be removed as reported by William in [1]. With this change, mod_devicetable.h needs to be added to define the 'of_device_id' struct. [1] https://lkml.org/lkml/2020/2/10/1516Reported-by:

Modify NPCM ADC reset support from direct register access to reset controller support. please make sure to modify NPCM adc device tree parameters as described at nuvoton,npcm-adc.txt document for using this change. Note for anyone noting that this is a breaking change, this is on a BMC and effectively in a close ecosystem so it is fine to rely on DT and kernel being updated together. Signed-off-by:

Add suspend and resume operations for being used by optional power management. The suspend function is switching off an GPIO which can be used by the hardware to switch power off. The resume function is switching the GPIO on and sleeps an adjustable time to give the device a chance to be up and running. If activated the driver gets into autosuspend after some time of inactivity. Suggested-by:

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.

There are a few places where a service's reference count is incremented, something quick is done, and the refcount is dropped. This can be made a little simpler/faster by not grabbing a reference in these cases. Signed-off-by:

Currently reference counts are implemented by locking service_spinlock and then incrementing the service's ->ref_count field, calling kfree() when the last reference has been dropped. But at the same time, there's code in multiple places that dereferences pointers to services without having a reference, so there could be a race there. It should be possible to avoid taking any lock in unlock_service() or service_release() because we are setting a single array element to NULL, and on service creation, a mutex is locked before looking for a NULL spot to put the new service in. Using a struct kref and RCU-delaying the freeing of services fixes this race condition while still making it possible to skip grabbing a reference in many places. Also it avoids the need to acquire a single spinlock when e.g. taking a reference on state->services[i] when somebody else is in the middle of taking a reference on state->services[j]. Signed-off-by:
