In this case we only gain the ability to have the compiler drop the
struct dev_pm_ops because the callbacks are called from paths other
than suspend and resume. In general the purpose of this new macro
is to allow automated removal of the callbacks as well, but that doesn't
apply here.

Instead of registering callback to process sensor events right at
initialization time, wait for the sensor to be register in the iio
subsystem.
Events can come at probe time (in case the kernel rebooted abruptly
without switching the sensor off for instance), and be sent to IIO core
before the sensor is fully registered.

To provide a new IIO trigger to the IIO core, usually driver executes the
following pipeline: allocate()/register()/get(). Before, IIO core assigned
trig->owner as a pointer to the module which registered this trigger at
the register() stage. But actually the trigger object is owned by the
module earlier, on the allocate() stage, when trigger object is
successfully allocated for the driver.
This patch moves trig->owner initialization from register()
stage of trigger initialization pipeline to allocate() stage to
eliminate all misunderstandings and time gaps between trigger object
creation and owner acquiring.

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.

- New driver for Qualcomm SPMI Round Robin ADC including necessary
additional utility functions in SPMI core and related MFD driver.
* ti-dac55781

Features

- 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.

The read on in_illuminance_input keeps at 0 after system sleep.
So add proper suspend and resume callback to make the sensor keep
working after system sleep.

The calibration is launched from prepare callback.
The ADC state when entering this function may be unknown as the
ADC may have been left enabled by boot stage.
One prerequisite for ADC calibration is to have ADC in disabled state.
If the calibration is started when ADC is still enabled, the behavior is
unpredictable, and the calibration may fail with a timeout error.
Force ADC to disabled state in stm32h7_adc_selfcalib().
ADC enabling is ensured by stm32h7_adc_enable() call,
before leaving prepare callback.

From ADC reference manual the software is allowed to write the
control bit ADDIS of the ADC_CR register only if the ADC is enabled.
Return immediately from stm32h7_adc_disable() if ADC is already disabled.

Most of these have been in next for a long time. Unfortunately there
was one stray patch in the branch (wasn't a fix), so I've just rebased
