There is one regmap_bulk_read() call in mpu3050_trigger_handler
that we have caught its return value bug lack further handling.
Check and terminate the execution flow just like the other three
regmap_bulk_read() calls in this function.

This patch fixes 2 issues of timestamp channel:
1. This patch ensures that there is sufficient space and correct
alignment for the timestamp.
2. Correct the timestamp channel scan index.

Fix an off by three orders of magnitude error in the AB8500
GPADC driver. Luckily it showed up quite quickly when trying
to make use of it. The processed reads were returning
microvolts, microamperes and microcelsius instead of millivolts,
milliamperes and millicelsius as advertised.

Seems that there are config combinations in which this driver gets enabled
and hence selects the MFD, but with out HAS_IOMEM getting pulled in
via some other route.  MFD is entirely contained in an
if HAS_IOMEM block, leading to the build issue in this bugzilla.

This is to silence a new Smatch warning:

    drivers/iio/imu/adis16400.c:492 adis16400_initial_setup()
    warn: sscanf doesn't return error codes

If the condition "if (st->variant->flags & ADIS16400_HAS_SLOW_MODE) {"
is false then we return 1 instead of returning 0 and probe will fail.

Add support for Thermal Monitoring part of PMIC5. This part is closely
coupled with ADC, using it's channels directly. ADC-TM support
generating interrupts on ADC value crossing low or high voltage bounds,
which is used to support thermal trip points.

The ADI AXI ADC driver requires IO mem access and OF to work. This change
adds these dependencies to the Kconfig symbol of the driver.

This was also found via the lkp bot, as the
devm_platform_ioremap_resource() symbol was not found at link-time on the
S390 architecture.
