The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

REG11[0] - selects Vref. 0 - calibration voltage, 1 - VDDA. txlx and later
SoCs support VDDA or calibration voltage as Vref, but others
support only calibration voltage. For newer platforms vendor
uses VDDA as default.
REG11[1] - reserved bit. g12a and later SoCs must write 1, others SoCs
write 0.
REG11[5] - Vref voltage. 0 - 0.9v, 1 - 1.8v. g12a and later SoCs must
write 0, others SoCs write 1.
REG11[6] - selects common-mode voltage, 0: from AVDD, 1: from Vref.

analog signal, which can be applied to power detection and key detection.
Theoretically, this ADC can support up to 16 channels. All SoCs below
contain this GPADC IP. The only difference between them is the number
of available channels:
T113 - 1 channel
D1 - 2 channels

The affected lines were resulting in a NULL pointer dereference on our
platform because the device tree contained the following list of
compatible strings:
power-sensor@40 {
compatible = "ti,ina232", "ti,ina231";
...
};
Since the driver doesn't declare a compatible string "ti,ina232", the OF
matching succeeds on "ti,ina231". But the I2C device ID info is
populated via the first compatible string, cf. modalias population in
of_i2c_get_board_info(). Since there is no "ina232" entry in the legacy
I2C device ID table either, the struct i2c_device_id *id pointer in the
probe function is NULL.
Fix this by using the already populated type variable instead, which
points to the proper driver data. Since the name is also wanted, add a
generic one to the ina2xx_config table.

According to the datasheets of supported meson SoCs length of ADC_CLK_DIV
field is 6-bit. Although all supported SoCs have the register
with that field documented later SoCs use external clock rather than
ADC internal clock so this patch affects only meson8 family (S8* SoCs).

Pointer to indio_dev structure is obtained via spi_get_drvdata() at

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 e9849777d0 ("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.

Set the read_label() callback to return a friendly name provided in DT
(firmware), in order to make in_{therm,voltage}X_label attributes show
up in sysfs for userspace to consume a channel name. This is
particularly useful for custom thermistors being attached to otherwise
generically named GPIOs, where the name is known by the board DT.
If the channel name isn't set in DT, use the datasheet_name hardcoded in
the driver instead.
Note that this doesn't fall back to fwnode_get_name() as that provides
suboptimally readable names, with an @xx address suffix from board DT.

Since the migration to fwnode_get_name in commit 4f47a236a2 ("iio:
adc: qcom-spmi-adc5: convert to device properties") the resulting
adc5_channel_prop::channel_name (renamed from datasheet_name in the
previous patch) - which is propagated into iio_chan_spec::extend_name -
was containing the DT node name including @xx suffix if a "label"
property is not present, while adc5_channels::datasheet_name was thus
far set by the macros but always remained unread. Put it to use instead
of using a confusing name containing @xx in sysfs filenames (again, when
"label" is not set).

iio_chan_spec::datasheet_name expects a channel/pin name on the hardware
part, i.e. from its datasheet, instead of a friendly name from DT which
typically describes the use of said channel. GPIO channels are commonly
specialized in QCOM board DTS based on what a - typically thermistor -
is connected to.
Also rename adc5_channel_prop::datasheet_name to channel_name to that
effect.
