Define the sysfs interface for toggle or dither capable channels. Dither
capable channels will have the extended interface:

 * out_voltageY_dither_en
 * out_voltageY_dither_raw
 * out_voltageY_dither_offset
 * out_voltageY_dither_raw_available
 * out_voltageY_dither_frequency
 * out_voltageY_dither_frequency_available
 * out_voltageY_dither_phase
 * out_voltageY_dither_phase_available

Toggle enabled channels will have:

 * out_voltageY_toggle_en
 * out_voltageY_raw0
 * out_voltageY_raw1
 * out_voltageY_symbol

The common interface present in all channels is:

 * out_voltageY_raw (not present in toggle enabled channels)
 * out_voltageY_raw_available
 * out_voltageY_powerdown
 * out_voltageY_scale
 * out_voltageY_offset
 * out_voltageY_calibbias

The LTC2688 is a 16 channel, 16 bit, +-15V DAC with an integrated
precision reference. It is guaranteed monotonic and has built in
rail-to-rail output buffers that can source or sink up to 20 mA.

1st set of IIO new device support, features and cleanup for 5.17

Includes some fixes that were either late breaking, low priority or
complex enough to not be good to rush in late in the cycle.

Tree rebased today to fix up some trivial issues + pull in a fix that
was previously on the fixes-togreg branch. Vast majority have been
in linux-next for some time now.

New device support
* adi,ad7293
  - New driver and bindings for this Power Amplifier drain current
    controller.  A complex device with various related monitoring functions.
* adi,ad75513R
  - New driver and bindings for this combined ADC and DAC device.
  - A few follow up fixes.
* adi,admv8818
  - New driver (and type) for this 2-18GHz filter device. Includes
    bindings and ABI documentation to allow clk_notifier based auto
    adjustment of the filters in appropriate applications.
* liteon,ltr501
  - Support for the ltr303.  ID and chip specific info table.
* xilinx,ams
  - New generic firmware function fwnode_iomap() as used in this driver.
  - New driver and bindings for this ADC and on-chip sensors as found
    in various Xilinx devices.

Core
* Introduced IIO_VAL_INT_64 which uses val and val2 in IIO callbacks to
  form a 64 bit integer when higher precision needed.
* Allow IIO_ENUM_AVAILABLE to be used with different shared values.
* Fix a long term issue with scheduling whilst atomic when iio_trig_poll()
  is called but no trigger consumers are actually enabled and hence the
  trigger may be reenabled from the interrupt handler.  Seen in the wild
  on the tsc2046.
* Mark iio_device_type const.
* buffer: Use a separate index variable to simplify code.
* buffer-dma: Clear out unused struct iio_buffer_block
* buffer-dmaengine: Switch to cheaper round_down() as power of 2 values.

Tests/tools
* format_value
  - Check against NULL returns from allocations in tests.
  - Add IIO_VAL_INT_64 test case.
* event_monitor
  - Flush the output after event to given more consistent latency
    when tool output piped to other programs.

Driver Features
* axp20x
  - Add support for NTC thermistor channel and document TS pin binding.
* arm,scmi
  - Add reading of raw channel values (using IIO_VAL_INT_64)
* liteon,ltr501
  - Add proximity-near-level support and dt-binding.

Tree wide cleanup
* Remove no-op trigger ops from multiple drivers.
* Stop using dev_get_drvdata() on the iio_dev->dev in various drivers
  and then stop assigning it to allow this to be used for other purposes.
  We can always get to the indio_dev using dev_to_iio_dev() which is
  a container_of() based approach. Also cleanup up some related unnecessary
  convoluted cases.
  - atmel,at91-sam5d2
  - nxp,imx7d
  - meas,ms5611
  - st,st_sensors
* Where available (or easy to introduce) use the scan_type.* values
  in place of a second copy for read_raw and similar paths.

* atmel,at91-sama5d2
  - Fix wrong cast of iio_dev->dev to platform_device that happened to
    be harmless.
* fsl,mma7660
  - Stop i2c remove() function returning an error code. Part of a rework
    to eventually stop returning anything from these.
* fsl,mma8452
  - Use correct type for local irqreturn_t.
* nxp,imx8mq
  - Maintainer email address update.
* nxp,lpc18xx_adc
  - Ensure clk_prepare_enable() called before clk_get_rate().
  - Switch of.h for mod_devicetable.h to reflect no of specific functions,

Unfortuanately a non standards compliant ACPI ID is known to be
in the wild on some AAEON boards.

Partly revert the removal of these IDs so that ADC081C will again
work + add a comment to that affect for future reference.

Whilst here use generic firmware properties rather than the ACPI
specific handling previously found in this driver.

I don't believe it's possible to hit this, because we drop
out of __iio_update_buffers() earlier in the event of an empty
list.  However, that is not visible to the compiler so lets
return an error if we do hit the loop with an empty bitmask.

The AMS includes an ADC as well as on-chip sensors that can be used to
sample external voltages and monitor on-die operating conditions, such
as temperature and supply voltage levels. The AMS has two SYSMON blocks.
PL-SYSMON block is capable of monitoring off chip voltage and
temperature.

PL-SYSMON block has DRP, JTAG and I2C interface to enable monitoring
from an external master. Out of these interfaces currently only DRP is
supported. Other block PS-SYSMON is memory mapped to PS.

The AMS can use internal channels to monitor voltage and temperature as
well as one primary and up to 16 auxiliary channels for measuring
external voltages.

The voltage and temperature monitoring channels also have event capability
which allows to generate an interrupt when their value falls below or
raises above a set threshold.

This patch introduces a new helper routine - fwnode_iomap(), which
allows to map the memory mapped IO for a given device node.

This implementation does not cover the ACPI case and may be expanded
in the future. The main purpose here is to be able to develop resource
provider agnostic drivers.

A bug exists if the user executes a COUNTER_ADD_WATCH_IOCTL ioctl call,
and then executes a COUNTER_DISABLE_EVENTS_IOCTL ioctl call. Disabling
the events should disable the 104-QUAD-8 interrupts, but because of this
bug the interrupts are not disabling.

The reason this bug is occurring is because quad8_events_configure() is
called when COUNTER_DISABLE_EVENTS_IOCTL is handled, but the
next_irq_trigger[] array has not been cleared before it is checked in
the loop.

This patch fixes the bug by removing the next_irq_trigger array and
instead utilizing a different algorithm of walking the events_list list
for the current requested events. When a COUNTER_DISABLE_EVENTS_IOCTL is
handled, events_list will be empty and thus all device channels end up
with interrupts disabled.

With 'unevaluatedProperties' support implemented, the following warnings
are generated in the nvmem examples:

Documentation/devicetree/bindings/nvmem/st,stm32-romem.example.dt.yaml: efuse@1fff7800: Unevaluated properties are not allowed ('reg' was unexpected)
Documentation/devicetree/bindings/nvmem/rmem.example.dt.yaml: nvram@10000000: Unevaluated properties are not allowed ('reg' was unexpected)
Documentation/devicetree/bindings/nvmem/brcm,nvram.example.dt.yaml: nvram@1eff0000: Unevaluated properties are not allowed ('reg' was unexpected)

Add the missing 'reg' property definition.
