The Sigma-Delta ADCs supported by this driver can use SDO as an interrupt
line to indicate the completion of a conversion. However, some devices
cannot properly detect the completion of a conversion by an interrupt.
This is for the reason mentioned in the following commit.
commit e9849777d0e2 ("genirq: Add flag to force mask in
disable_irq[_nosync]()")
A read operation is performed by an extra interrupt before the completion
of a conversion. At this time, the value read from the ADC data register
is the same as the previous conversion result. This patch fixes the issue
by setting IRQ_DISABLE_UNLAZY flag.

If only adc differential channels are defined driver will fail with
stm32-adc: probe of 48003000.adc:adc@0 failed with error -22
Fix this by skipping the initialization if no channels are defined.
This applies only to the legacy way of initializing adc channels.

The AD7192 provides a specific channel configuration where both negative
and positive inputs are connected to AIN2. This was represented in the
ad7192 driver as a IIO channel with .channel = 2 and .extended_name set
to "shorted".
The problem with this approach, is that the driver provided two IIO
channels with the identifier .channel = 2; one "shorted" and the other
not. This goes against the IIO ABI, as a channel identifier should be
unique.
Address this issue by changing "shorted" channels to being differential
instead, with channel 2 vs. itself, as we're actually measuring AIN2 vs.
itself.
Note that the fix tag is for the commit that moved the driver out of
staging. The bug existed before that, but backporting would become very
complex further down and unlikely to happen.

Valid values for "adc_chan" are zero to (PALMAS_ADC_CH_MAX - 1).
Smatch detects some buffer overflows caused by this:

The problem is these lines:
ret = vref_uv = regulator_get_voltage(adc->vref);
if (ret < 0)
The "ret" variable is type long and "vref_uv" is u32 so that means
the condition can never be true on a 64bit system. A negative error
code from regulator_get_voltage() would be cast to a high positive
u32 value and then remain a high positive value when cast to a long.
The "ret" variable only ever stores ints so it should be declared as
an int. We can delete the "vref_uv" variable and use "ret" directly.

Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost breaks
even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem
- FPGA driver updates
- New driver subsystem, CDX, for AMD systems
- lots of other small driver updates and additions
All of these have been in linux-next for a while with no reported

Merge ACPI bus type driver changes, ACPI backlight driver updates and a

clean up code in acpi_sb_notify() (Rafael Wysocki).
- Remove register_backlight_delay module option and code and remove
quirks for false-positive backlight control support advertised on
desktop boards (Hans de Goede).

The palmas gpadc block has support for monitoring up to 2 ADC channels
and issue an interrupt if they reach past a set threshold. This change
hooks into the IIO events system and exposes to userspace the ability to
configure these threshold values for each channel, but only allow up to
2 such thresholds to be enabled at any given time. Trying to enable a
third channel will result in an error.
Userspace is expected to input calibrated, as opposed to raw, values as
threshold. However, it is not enough to do the opposite of what is done
when converting the other way around. To account for tolerances in the
ADC, the calculated raw threshold should be adjusted based on the ADC
specifications for the device. These specifications include the integral
nonlinearity (INL), offset, and gain error. To adjust the high
threshold, use the following equation:
(calibrated value + INL) * Gain error + offset = maximum value [1]
Likewise, use the following equation for the low threshold:
(calibrated value - INL) * Gain error - offset = minimum value
The gain error is a combination of gain error, as listed in the
datasheet, and gain error drift due to temperature and supply. The exact
values for these specifications vary between palmas devices. This patch
sets the values found in TWL6035, TWL6037 datasheet.

The palmas gpadc block has support for monitoring up to 2 ADC channels
and issue an interrupt if they reach past a set threshold. This is
currently used to wake up the system from sleep, but the functionality
is more generic than that. As such, change the naming of functions and
variables to refer to it as events instead, except during suspend and
resume where wakeup still make sense.

It does not seem to be used by anyone and later patches in this series
are made simpler by first removing this. There is now a lot of dead code
that cannot be reached, until later patches revive it. Arguably, this is
preferred over removing the code only to add it again.

From the comment of platform_get_irq(), it only returns non-zero IRQ

The left side of the loop condition never becomes false. hwchan cannot be
NULL, because it points to elements of the hw_channels array that takes
one of 4 predefined values: pm8018_xoadc_channels, pm8038_xoadc_channels,
pm8058_xoadc_channels, pm8921_xoadc_channels.

Even though we are passing 'ret' as stop condition for
read_poll_timeout(), that return code is still being ignored. The reason
is that the poll will stop if the passed condition is true which will
happen if the passed op() returns error. However, read_poll_timeout()
returns 0 if the *complete* condition evaluates to true. Therefore, the
error code returned by op() will be ignored.
To fix this we need to check for both error codes:
* The one returned by read_poll_timeout() which is either 0 or
ETIMEDOUT.
* The one returned by the passed op().

meson_sar_adc_lock() might return an error if BL30 doesn't release its
lock on the hardware. Just returning early from .remove() is wrong
however as this keeps the clocks and regulators on which is never
cleaned up later.
Given the BL30 not giving up its lock is a strong hint for broken
behaviour, and there is nothing we can do about that: Just clean up
ignoring the fact that we're not holding the lock.

as necessary to avoid that. Regroup macros based on chip type, and

The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.
In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.
Use the devdata accessor introduced in the previous patch.
No functional changes intended.

- New hwtracing drivers and additions to that subsystem
- lots of interconnect changes and new drivers as that subsystem seems
under very active development recently. This required also merging
in the icc subsystem changes through this tree.
- FPGA driver updates
- counter subsystem and driver updates
- MHI driver updates
- nvmem driver updates

This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate subsystem
trees, but the majority is in the same branch, in order to better handle
dependencies between the patches and avoid breaking bisection.
Unfortunately that leads to merge conflicts against other changes in the
subsystem trees, but they should all be trivial to resolve by removing
the files.
See commit 7d0d3fa7339e ("Merge tag 'arm-boardfiles-6.0' of
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
description of which machines were marked unused and are now removed. The
only removals that got postponed are Terastation WXL (mv78xx0) and
Jornada720 (StrongARM1100), which turned out to still have potential
users.

Correct the "sub_lsb" shift for the ltc2497 and drop the sub_lsb element
which is now constant.
An earlier version of the code shifted by 14 but this was a consequence
of reading three bytes into a __be32 buffer and using be32_to_cpu(), so
eight extra bits needed to be skipped. Now we use get_unaligned_be24()
and thus the additional skip is wrong.
