Second set of IIO new device support, features and cleanups for the 4.21 cycle.
Staging graduation
* ad2s90
- Driver for this resolver to digital chip.
New drivers and device support.
* ad5686
- Add support for ad5310r DAC and associated fix in value read back.
* exynos-adc
- Support for S5PV210 which is slightly different from other parts.
* mcp41010
- Driver supporting MCP41010, MCP41050, MCP41100, MCP42010, MCP42050 and
MCP42100 microchip potentiometers.
New ACPI ids.
* ak8975
- AKM9911 ACPI HID.
* kxcjk-1013
- KXJ2109 ACPI HID.
- KIOX010A ACPI HID.
New features
* ad5933
- Explicit DT binding.
* ad2s90
- Explicit DT binding including dropping spi setup that is done via dt
in favour of verifying the settings form DT.
* adt7316
- Explicit DT binding and support for gpio, irq_flags etc.
* stm32-adc
- Runtime power management.
Minor fixes and cleanups
* core
- Protect against missing info structure.
* ad2s90
- SPDX
- Add documentation fo the mutex.
* ad7280a
- Check allocation failure.
- Fix an accidental replacement of an error return.
* adt7316
- Switch some variables to be local and rename for consistency with other
drivers.
- Revert a false handling of 0 as an error introduced earlier this cycle.
* bmi160
- Use devm functions throughout probe() to avoid need for remove().
* hid-sensor-hub
- White space cleanup.
* hts221
- MAINTAINERS entry.
* lis302
- Use generic name in the DT binding doc.
* Messon-saradc
- Check for allocation error.
- Fix some presented clock names that break clk debugfs.
* qcom-spmi-adc
- A fix for initialization of the prescale property. Came late in the
cycle, so merge window is probably the best route for this.
* st_lsm6dsx
- Allow for variable read length to support wider range of slave devices.
