Letting the compiler remove these functions when the kernel is built
without CONFIG_PM support is simpler and less error prone than the
use of #ifdef based config guards.

Removing instances of this approach from IIO also stops them being
copied into new drivers.

Very likely it would be safe to use DEFINE_RUNTIME_DEV_PM_OPS() here,

misc: Add a mechanism to detect stalls on guest vCPUs

This driver creates per-cpu hrtimers which are required to do the
periodic 'pet' operation. On a conventional watchdog-core driver, the
userspace is responsible for delivering the 'pet' events by writing to
the particular /dev/watchdogN node. In this case we require a strong
thread affinity to be able to account for lost time on a per vCPU.

This part of the driver is the 'frontend' which is reponsible for
delivering the periodic 'pet' events, configuring the virtual peripheral
and listening for cpu hotplug events. The other part of the driver is
an emulated MMIO device which is part of the KVM virtual machine
monitor and this part accounts for lost time by looking at the
/proc/{}/task/{}/stat entries.

Merge tag 'iio-for-5.20a' of https://git./linux/kernel/git/jic23/iio into char-misc-next

Jonathan writes:

IIO new device support, features and minor fixes for 5.20

Several on-running cleanup efforts dominate this time, plus the DMA
safety alignment issue identified due to improved understanding of
the restrictions as a result of Catalin Marinas' efforts in that area.

One immutable branch in here due to MFD and SPMI elements needed for
the qcom-rradc driver.

Device support
* bmi088
  - Add support for bmi085 (accelerometer part of IMU)
  - Add support for bmi090l (accelerometer part of IMU)
* mcp4922
  - Add support for single channel device MCP4921
* rzg2l-adc
  - Add compatible and minor tweaks to support RZ/G2UL ADC
* sca3300
  - Add support for scl3300 including refactoring driver to support
    multiple device types and cleanup noticed whilst working on driver.
* spmi-rradc
  - New driver for Qualcomm SPMI Round Robin ADC including necessary
    additional utility functions in SPMI core and related MFD driver.
* ti-dac55781
  - Add compatible for DAC121C081 which is very similar to existing parts.

Features
* core
  - Warn on iio_trigger_get() on an unregistered IIO trigger.
* bma400
  - Triggered buffer support
  - Activity and step counting
  - Misc driver improvements such as devm and header ordering
* cm32181
  - Add PM support.
* cros_ec
  - Sensor location support
* sx9324
  - Add precharge resistor setting
  - Add internal compensation resistor setting
  - Add CS idle/sleep mode.
* sx9360
  - Add precharge resistor setting
* vl53l0x
  - Handle reset GPIO, regulator and relax handling of irq type.

Cleanup and minor fixes:

Treewide changes
- Cleanup of error handling in remove functions in many drivers.
- Update dt-binding maintainers for a number of ADI bindings.
- Several sets of conversion of drivers from device tree specific to
  generic device properties. Includes fixing up various related
  header and Kconfig issues.
- Drop include of of.h from iio.h and fix up drivers that need to include
  it directly.
- More moves of clusters of drivers into appropriate IIO_XXX namespaces.
- Tree wide fix of a long running bug around DMA safety requirements.
  IIO was using __cacheline_aligned to pad iio_priv() structures. This
  worked for a long time by coincidence, but correct alignment is
  ARCH_KMALLOC_MINALIGN.  As there is activity around this area, introduce
  an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather
  than every driver in future. Note, there have been no reports of this
  bug in the wild, and it may not happen on any platforms supported by
  upstream, so no rush to backport these fixes.

Other cleanup
* core
  - Switch to ida_alloc()/free()
  - Drop unused iio_get_time_res()
  - Octal permissions and DEVICE_ATTR_* macros.

iio: adc: xilinx-xadc: Drop duplicate NULL check in xadc_parse_dt()

The fwnode_for_each_child_node() is NULL-aware, no need to check
its parameters outside. Drop duplicate NULL check in xadc_parse_dt().

iio: adc: xilinx-xadc: Make use of device properties

Convert the module to be property provider agnostic and allow
it to be used on non-OF platforms.

Add mod_devicetable.h include.

Merge tag 'misc-habanalabs-next-2022-07-12' of https://git./linux/kernel/git/ogabbay/linux into char-misc-next

Oded writes:

This tag contains habanalabs driver changes for v5.20:

- Add Gaudi2 ASIC support. All the features required for Gaudi2 are included
  in this tag (except the networking aspect).

- Add more events to the eventfd support in the driver. With the new code, we
  expose three events that the user can register to get notification about them.

- re-factor soft reset code and replace its name to compute reset to better
  reflect the actual reset done in new ASICs

- Change the way Gaudi2 triggers an MSI-X interrupt due to h/w bug.

- Improve the code of the debugfs node that scrubs the device's memory.

- Add mechanism for better compatibility with older f/w versions

- Cleanup kernel log prints by moving some prints to debug and removing others.

- Many small bug fixes and minor changes.
