Commit 4c3577db3e4f ("Staging: iio: impedance-analyzer: Fix sparse
warning") fixed a compiler warning, but introduced a bug that resulted
in one of the two 16 bit IIO channels always being zero (when both are
enabled).
This is because int is 32 bits wide on most architectures and in the
case of a little-endian machine the two most significant bytes would
occupy the buffer for the second channel as 'val' is being passed as a
void pointer to 'iio_push_to_buffers()'.
Fix by defining 'val' as u16. Tested working on ARM64.

When a software reset is performed on the AD2S1210 to make the selected
excitation frequency take effect, it always triggers faults on the
input signals because the output signal is interrupted momentarily.
So we need to clear the faults after the software reset to avoid
triggering fault events the next time a sample is read.
The datasheet specifies a time t[track] in Table 27 that specifies the
settle time in milliseconds after a reset depending on the selected
resolution. This is used in the driver to add an appropriate delay.

This refactors the sample line toggle in the ad2s1210 resolver driver
to a separate function. The sample has some timing requirements, so
this ensures that it is always done the same way, both in the existing
call sites and any future usage.
Previously, the sample line was kept on for the duration of the read,
but this is not necessary. Data is latched in on the rising edge and
after the specified delay the state of the sample line does not matter.

Faults have been converted to events and we are now polling the fault
register each time we read a sample, so we no longer need the fault
attribute.
This attribute was not suitable for promotion out of staging anyway
since it was returning multiple values in a single attribute.
The fault clearing feature should not be needed unless we need to
support the fault output pins on the chip which is not currently
supported. So we can add this feature back in if we need it later.

The AD2S1210 has a programmable threshold for the degradation of signal
(DOS) mismatch fault. This fault is triggered when the difference in
amplitude between the sine and cosine inputs exceeds the threshold.
The DOS reset min/max registers on the chip provide initial values
for internal tracking of the min/max of the monitor signal after the
fault register is cleared.
This patch converts the custom device DOS reset min/max threshold
attributes custom event attributes on the monitor signal channel.
The attributes now use millivolts instead of the raw register value in
accordance with the IIO ABI.

The AD2S1210 has a programmable threshold for the degradation of signal
(DOS) mismatch fault. This fault is triggered when the difference in
voltage between the sine and cosine inputs exceeds the threshold. In
other words, when the magnitude of sine and cosine inputs are equal,
the AC component of the monitor signal is zero and when the magnitudes
of the sine and cosine inputs are not equal, the AC component of the
monitor signal is the difference between the sine and cosine inputs.
So the fault occurs when the magnitude of the AC component of the
monitor signal exceeds the DOS mismatch threshold voltage.
This patch converts the custom device DOS mismatch threshold attribute
to an event magnitude attribute on the monitor signal channel.
The attribute now uses millivolts instead of the raw register value in
accordance with the IIO ABI.
Emitting the event will be implemented in a later patch.

The AD2S1210 has a programmable threshold for the loss of signal (LOS)
fault. This fault is triggered when either the sine or cosine input
falls below the threshold voltage.
This patch converts the custom device LOS threshold attribute to an
event falling edge threshold attribute on a new monitor signal channel.
The monitor signal is an internal signal that combines the amplitudes
of the sine and cosine inputs as well as the current angle and position
output. This signal is used to detect faults in the input signals.

accordance with the IIO ABI.

The AD2S1210 monitors the internal error signal (difference between
estimated angle and measured angle) to determine a loss of position
tracking (LOT) condition. When the error value exceeds a threshold, a
fault is triggered. This threshold is user-configurable.
This patch converts the custom lot_high_thrd and lot_low_thrd attributes
in the ad2s1210 driver to standard event attributes. This will allow
tooling to be able to expose these in a generic way.
Since the low threshold determines the hysteresis, it requires some
special handling to expose the difference between the high and low
register values as the hysteresis instead of exposing the low register
value directly.
The attributes also return the values in radians now as required by the
ABI.
Actually emitting the fault event will be done in a later patch.

Selecting the resolution was implemented as the `bits` sysfs attribute.
However, the selection of the resolution depends on how the hardware
is wired and the specific application, so this is rather a job for
devicetree to describe.
A new devicetree property `assigned-resolution-bits` to specify the
resolution required for each chip is added and the `bits` sysfs
attribute is removed.
Since the resolution is now supplied by a devicetree property, the
resolution-gpios are now optional and we can allow for the case where
the resolution pins on the AD2S1210 are hard-wired instead of requiring
them to be connected to gpios.

The ad2s1210 driver has a device-specific attribute `fexcit` for setting
the frequency of the excitation output. This converts it to a channel in
order to use standard IIO ABI.
The excitation frequency is an analog output that generates a sine wave.
Only the frequency is configurable. According to the datasheet, the
specified range of the excitation frequency is from 2 kHz to 20 kHz and
can be set in increments of 250 Hz.

When reading registers on the AD2S1210 chip, we have to supply a "dummy"
address for the second SPI tx byte so that we don't accidentally write
to a register. This register will be read and the value discarded on the
next regmap read or write call.
Reading the fault register has a side-effect of clearing the faults
so we should not use this register for the dummy read.

This makes use of the regmap API to read and write the configuration
registers. This simplifies code quite a bit and makes it safer
(previously, it was easy to write a bad value to the config registers
which causes the chip to lock up and need to be reset).
This chip has multiple modes of operation. In normal mode, we do not use
regmap since there is no addressing - data is just bitshifted out during
the SPI read. In config mode, we use regmap since it requires writing
the address (with read/write flag) before reading and writing.
We don't use the lock provided by the regmap because we need to also
synchronize with the normal mode SPI reads and with the various GPIOs.
There is also a quirk when reading registers (other than the fault
register). If the address/data bit is set in the value read, then it
indicates there is a configuration parity error and the data is not
valid. Previously, this was checked in a few places, but not
consistently. Now, we always check it in the regmap read function.

This removes the fclkin sysfs attribute and replaces it with getting
the CLKIN clock rate using the clk subsystem (i.e. from the devicetree).
CLKIN comes from an external oscillator that is connected directly to
the AD2S1210 chip, so users of the sysfs attributes should not need to
be concerned with this.
The fclkin field (the datasheet name) is renamed to clkin_hz to be more
obvious that it is a frequency in Hz.

This removes the special handling for resolutions lower than 16 bits.
This will allow us to use a fixed scale independent of the resolution.
A new sample field is added to store the raw data instead of reusing
the config mode rx buffer so that we don't have to do a cast or worry
about unaligned access.
Also, for the record, according to the datasheet, the logic for the

Pull staging driver updates from Greg KH:
"Here is the large set of staging driver updates for 6.4-rc1. Once
again, we removed more code than was added, a nice trend.
It was a calm cycle, mostly all just small coding style cleanups,
included in here are:
- removal of the greybus loopback testing tools, userspace code that
didn't belong in a driver subdirectory and was causing problems for
some build systems
- platform remove callback cleanups
- rtl8192e huge cleanups
- other small staging driver cleanups.
All of these have been in linux-next for a while with no reported
problems"

With linux/acpi.h no longer implicitly including of.h, add an explicit
include of of.h to fix the following error:
drivers/staging/iio/resolver/ad2s1210.c:706:21: error: implicit declaration of function 'of_match_ptr' is invalid in C99 [-Werror,-Wimplicit-function-declaration]

This driver is so far from making correct use of the IIO infrastructure
and ABI that if someone wanted to make the driver suitable for moving
out of staging, they would more or less be starting from scratch.
As such there is little point in keeping the existing code in staging.
Note this was only user of the meter.h header so that is dropped.
There are no other drivers in the staging/iio/meter directory so drop
the build system files as well.

Call '__adis_initial_startup()' instead of its locked variant in
'adis16240_probe()'.
The locks are not needed at this point.

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.
