The SPMI VADC and the earlier XOADC share a subset of
common code, so to be able to use the same code in both
drivers, we break out a separate file with the common code,
prefix exported functions that are no longer static with
qcom_* and bake an object qcom-spmi-vadc.o that contains both
files: qcom-vadc-common.o and qcom-spmi-vadc-core.o.
As we need to follow the procedure for making a kernel module
or compiled in object from several files, but still want to
produce the same module name, rename the qcom-spmi-vadc.c
file to qcom-spmi-vadc-core.c so we can bake the two objects
into qcom-spmi-vadc.o

This adds support for the Allwinner A33 thermal sensor.
Unlike the A10, A13 and A31, the Allwinner A33 only has one channel
which is dedicated to the thermal sensor. Moreover, its thermal sensor
does not generate interruptions, thus we only need to directly read the
register storing the temperature value.
The MFD used by the A10, A13 and A31, was created to avoid breaking the
DT binding, but since the nodes for the ADC weren't there for the A33,
it is not needed.
Though the A33 does not have an internal ADC, it has a thermal sensor
which shares the same registers with GPADC of the already supported SoCs
and almost the same bits, for the same purpose (thermal sensor).
The thermal sensor behaves exactly the same (except the presence of
interrupts or not) on the different SoCs.

This moves code used in MFD probing to a new sun4i_gpadc_probe_mfd
function.
This driver was initially written for A10, A13 and A31 SoCs which
already had a DT binding for this IP, thus we needed to use an MFD to
probe the different drivers without changing the DT binding of these
SoCs.
For SoCs that will require to create a DT binding for this IP, we can
avoid using an MFD, thus we need two separate functions: one for probing
via MFD and one for probing without MFD.
This split the code specific to MFD probing in a function separated from
the driver probe function.

When a hid sensor module is removed and modprobed again we see
error for unbalanced pm_runtime. This issue is caused by not
deactivating runtime PM on removal. So on modprobe again when
activated again, this will print this error.

This patch allows to avoid a transitory that occurs when a given sensor
has been already enabled (e.g. gyroscope) and the user is configuring
the sample frequency of the other one (e.g. accelerometer).
The transitory lasts until the accelerometer is enabled.
During that time slice the gyroscope ODR is incorrectly modified as well.
At the end of the transitory both sensors work at the right frequency.
Fix it introducing st_lsm6dsx_check_odr() routine to check ODR consistency
in write_raw handler in order to apply frequency configuration just
in st_lsm6dsx_set_odr()

With CONFIG_THERMAL=m and CONFIG_SUN4I_GPADC=y, we get a link error
from calling devm_thermal_zone_of_sensor_register:
drivers/iio/built-in.o: In function `sun4i_gpadc_probe':
:(.text+0x1c284): undefined reference to `devm_thermal_zone_of_sensor_register'
This adds a Kconfig dependency to ensure we can only have the ADC
driver as built-in when this function is also built-in, or when
we see the empty stub implementation. When the thermal code is
a module, we can still build the adc driver as a module, too.

LTC2497 ADCs. The LTC2497 is a 16-channel (eight differential),
16-bit, high precision, delta-sigma ADC with an automatic, differential,

The mpu9250 is a SIP containing an mpu6500 and an ak8975. If this was all
there was too it there would be no need for explicit handling in the driver.
Arguably the bindings would also only reflect the presence of an mpu6500 with
the ak8975 hanging off it, as the kernel doesn't care that they are in one
package.
However, the WHOAMI value changes as well so best to add explicit support.

On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC
has ADCs that are used for battery charging and USB PHY VBUS and ID pin
detection.
Unfortunately the only documentation for this ADC seems to be the
Motorola mapphone Linux kernel tree. I have tested that reading raw and
scaled values works, but I have not used the timed sampling that the ADC
seems to support.
Let's add a minimal support for it so we can eventually provide IIO
channels for the related battery charging and USB PHY drivers.

The driver needs to insure atomicity during frequency
changes of bus and device. The iiodev->mlock as used
was not doing that. Replace it with the drivers existing
buffer lock and introduce an auxiliary spi_write() that does
not hold the lock.
