staging: fsl-mc/dpio: Fix early writing of valid bit
Commands written to the QMan software portals have a valid
bit in the "verb" field of the command that, when set with
the right value, notifies the hardware that the command is
fully written and ready to be processed.
The "verb" field should be the last one to be written in the
swp command registers, after all other fields are filled in.
The current implementation doesn't follow this rule for all
commands, which may result in an incompletely configured
command being processed by the hardware. Enforce the correct
order of writes to avoid this situation.

iio: imu: st_lsm6dsx: do not apply ODR configuration in write_raw handler
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()

iio: adc: cpcap: Add minimal support for CPCAP PMIC ADC
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.
