According to the datasheet and as defined in struct bmp280_comp_press, dig_p1 is
of type u16, while dig_p2 to dig_p9 are of type s16. In
bmp280_read_compensation_press(), values read from the device were treated as
the wrong type.
In bmp280_read_press() the fractional part of the measured pressure is
calculated wrong. A better way is to use *val for the raw pressure and *val2 for
the quotient and let the core do the proper conversion using IIO_VAL_FRACTIONAL.

The ADC on exynos7 is quite similar to ADCv2. The differences are as
follows:
- exynos7-adc has 8 input channels (as against 10 in ADCv2).
- exynos7 does not include an ADC PHY control register.
- Some ADC_CON2 register bits being used in ADCv2 are listed as
reserved in exynos7-adc. This results in a different init_hw
function for exynos7.

Instead of using the ADC_PHY register base address, use sysreg phandle
in ADC node to control ADC_PHY configuration register.
This patch adds syscon node for Exynos3250, Exynos4x12, Exynos5250,
and Exynos5420, Exynos5800.

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.

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.

This patch adds support to the Industrial IO subsystem
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.

Older Rockchip SoCs, at least the rk3066, used a slightly modified saradc
for temperature measurements. This so called tsadc does not contain any
active parts like temperature interrupts and only supports polling the
current temperature. The returned voltage can then be converted by a
suitable thermal driver to and actual temperature and used for thermal
handling.
