hwmon: (adm1275) Allow setting shunt reg value
...
The ADM series of hotswap controllers support extending
the current measurement range by using a sensing resistor
value other than the typical 1 mOhm. For example, using a 0.5 mOhm
sensing resistor doubles the maximal current can be measured.
Current driver assumes a shunt resistor value of 1 mOhm in calculation,
meaning for other resistor values, hwmon will report scaled
current/power measurements. This patch parses device tree parameter
"shunt-resistor-micro-ohms", if there is one.

The chip is quite similar to other chips in the series,
but as usual it comes with its own quirks.

hwmon: (adm1275) Add support for ADM1278
...
ADM1278 is mostly compatible to other chips of the same series.
Besides the usual difference in coefficients, it supports
a temperature sensor, and it can measure both input and output
voltage at the same time.

hwmon changes for v3.4
...
Mostly cleanup. No new drivers this time around, but support for several chips
added to existing drivers: TPS40400, TPS40422, MTD040, MAX34446, ZL9101M,
ZL9117M, and LM96080. Also, added watchdog support for SCH56xx, and additional
attributes for a couple of drivers.

ADM1275 supports a second current limit, which can be configured as either lower

critical current limit.
Also replace error return code EINVAL for unsupported pages with ENXIO as this
is more appropriate for the observed condition.
