Commit 1e23dcaa1a ("iio: imx8qxp-adc: Add driver support for NXP IMX8QXP
ADC") adds the config IMX8QXP_ADC for this new driver, which depends on
the non-existing config ARCH_MXC_ARM64.
Hence, ./scripts/checkkconfigsymbols.py warns:
ARCH_MXC_ARM64
Referencing files: drivers/iio/adc/Kconfig
Probably, the existing config ARCH_MXC is intended to be referred here.
So, repair the dependency to refer to that config.

Some I/Os are connected to ADC input channels, when the corresponding bit
in PCSEL register are set on STM32H7 and STM32MP15. This is done in the
prepare routine of stm32-adc driver.
There are constraints here, as PCSEL shouldn't be set when VDDA supply
is disabled. Enabling/disabling of VDDA supply in done via stm32-adc-core
runtime PM routines (before/after ADC is enabled/disabled).
Currently, PCSEL remains set when disabling ADC. Later on, PM runtime
can disable the VDDA supply. This creates some conditions on I/Os that
can start to leak current.
So PCSEL needs to be cleared when disabling the ADC.

Using `dev_get_drvdata()` in IIO sysfs callbacks to get a pointer to the
IIO device is a relic from the very early days of IIO. The IIO core as well
as most other drivers have switched over to using `dev_to_iio_dev()`
instead.
This driver is one of the last few drivers remaining that uses the outdated
idiom, update it. This will allow to eventually update the IIO core to no
longer set the drvdata for the IIO device and free it up for driver usage.

The at91-sama5d2 driver calls `to_platform_device()` on a struct device
that is part of a IIO device. This is incorrect since
`to_platform_device()` must only be called on a struct device that is part
of a platform device.
The code still works by accident because non of the struct platform_device
specific fields are accessed.
Refactor the code a bit so that it behaves identically, but does not use
the incorrect cast. This avoids accidentally adding undefined behavior in
the future by assuming the `struct platform_device` is actually valid.

The IIO core handles a trigger ops with all NULL callbacks the

slightly reduced.

The `imx7d_adc_enable()` and `imx7d_adc_disable()` functions are used as
the suspend and resume callbacks for the device. When called as
suspend/resume functions they are called with the platform_device's device
as their parameter.
In addition the functions are called on device probe and remove. In this
case they are passed the struct device of the IIO device that the driver
registers.
This works because in the `imx7d_adc_{enable,disable}()` functions the
passed struct device is only ever used as a parameter to `dev_get_drvdata()`
and `dev_get_drvdata()` returns the same value for the platform device and
the IIO device.
But for consistency we should pass the same struct device to the
`imx7d_adc_{enable,disable}()` in all cases. This will avoid accidental
breakage if the device is ever used for something more than
`dev_get_drvdata()`.
Another motivation is that `dev_get_drvdata()` on the IIO device relies on
the IIO core calling `dev_set_drvdata()`. Something we want to remove.

In some setups the IRQ signal of the XADC might not be wired to the host
system. The driver currently requires that an interrupt is specified. Make
the interrupt optional so the driver can be used in such setups where the
interrupt is not connected.
Since both the internal triggers as well as events depend on the interrupt
being connected both are not available when the interrupt is not connected.
Buffered access is still supported even without an interrupt since an
external trigger can be used.
The IRQ is only optional when using the AXI interface, since the PCAP
interface needs the IRQ for reading and writing registers.

clk_get_rate() is not guaranteed to work if called before
clk_prepare_enable().
Reorder clk_get_rate(), so it's called after clk_prepare_enable() and
after devm_add_action_or_reset() of lpc18xx_clk_disable().
Not that this is not a problem on this particular device, but it is
good to remove a case that might get copied elsewhere.

from non volatile memory for this channel.
vrefint channel is exposed as a processed channel returning

in the devices_deferred debugfs file.

The remove function and the goto sections are not necessary if devm
functions are used.
Convert device register to devm version. Add hook functions to release
device resources, and use them inside probe with devm_add_action,
which will release resources on driver detach.
To maintain the order of which device resources were released/reseted,
register the hook functions as soon as resources are obtained/initialized.
Since devres actions are called on driver detach, the remove
function and the error-handling goto sections are no longer necessary.

First set of IIO new device and feature support for the 5.16 cycle
Counter subsystem changes now sent separately.
This has been a busy cycle, so lots here and a few more stragglers to
come next week.
Big new feature in this cycle is probably output buffer support.
This has been in the works for a very long time so it's great to see
Mihail pick up the challenge and build upon his predecessors work to finally
bring this feature to mainline.
New device support
------------------
* adi,adxl313
- New driver and dt bindings for this low power accelerometer.
* adi,adxl355
- New driver and dt bindings for this accelerometer.
- Later series adds buffer support.
* asahi-kasei,ak8975
- Minor additions to driver to support ak09916
* aspeed,aspeed-adc
- Substantial rework plus feature additions to add support for the
ast2600 including a new dt bindings doc.
* atmel,at91_sama5d2
- Rework and support introduced for the sama7g5 parts.
* maxim,max31865
- New driver and bindings for this RTD temperature sensor chip.
* nxp,imx8qxp
- New driver and bindings for the ADC found on the i.MX 8QuadXPlus Soc.
* senseair,sunrise
- New driver and bindings for this family of carbon dioxide gas sensors.
* sensiron,scd4x
- New driver and bindings for this carbon dioxide gas sensor.
New features
------------
* Output buffer support. Works in a similar fashion to input buffers, but
in this case userspace pushes data into the kfifo which is then drained
to the device when a trigger occurs. Support added to the ad5766 DAC
driver.
* Core, devm_iio_map_array_register() to avoid need for
devm_add_action_or_reset() based cleanup in fully managed allocation
drivers.
* Core iio_push_to_buffers_with_ts_unaligned() function to safely handle a
few drivers where it really hard to ensure the correct data alignment in
an iio_push_to_buffers_with_timestamp() call. Note this uses a bounce
buffer so should be avoided whenever possible. Used in the ti,adc108s102,
invense,mpu3050 and adi,adis16400. This closes the last known set
of drivers with alignment issues at this interface.
* maxim,max1027
- Substantial rework to this driver main target of which was supporting
use of other triggers than it's own EOC interrupt.
- Transfer optimization.
* nxp,fxls8962af
- Threshold even support including using it as a wakeup source.
Cleanups, minor fixes etc

these patches just make it 'obvious' they always return 0 where it was the
