fafb37cfae iio: exyno-adc: use syscon for PMU register access
This patch updates the IIO based ADC driver to use syscon and regmap
APIs to access and use PMU registers instead of remapping the PMU
registers in the driver.

345b48307d iio:humidity:si7020: cleanup read_raw and probe
When reading temperature or humidity values, a shift of two bits to the right
needs to be applied, and only for the humidity channel a mask of the lower
12 bits needs to be applied. This reduces code repetition.
During probe, i2c_set_clientdata() was used, although its counterpart was not,
so drop it.

acd8256723 iio: inkern: Add of_xlate function to struct iio_info
When #iio-cells is greater than '0', the driver could provide
a custom of_xlate function that reads the *args* and returns
the appropriate index in registered IIO channels array.

Add simple translation function, suitable for the most 1:1
mapped channels in IIO chips, and use it when driver did not
provide custom implementation.

for the Silicon Labs Si7013/20/21 Relative Humidity and
Temperature Sensors.

Website: http://www.silabs.com/products/sensors/humidity-sensors/Pages/si7013-20-21.aspx

These are i2c devices which measure relative humidity
and temperature and all use the same protocol. The
Si7013 has an additional input with programmable
linearization which is not supported because that's
complicated and I didn't need it.

suitable thermal driver to and actual temperature and used for thermal
