Greetings,
The other day at [email protected] we discussed
the
possibility of having ADC channels voltage references moved to the DT [1].
In Freescale's i.MX28 and i.MX23, at least, the CPU has 16 ADC channels some of
which
are dedicated to measure internal stuff, like CPU temperature and voltages. Some
channels have different fixed divisors and so different reference voltages.
These reference voltages (in mV) are needed to calculate the scale to show
through the
sysfs IIO interface, so that a user can easily compute the real measured
voltage out
of the sampled data.
The proposed DT entry also appears at [1].
We would love to here opinions about it.

Any opinion about the suggestion of moving ADC reference voltages into the
device tree?
Thanks
