iio:pressure:bmp280: fix pressure calculation
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.

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.

iio: adc: rockchip_saradc: add support for rk3066-tsadc variant
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.
Vybrid ADC peripheral includes a temperature sensor
which is connected to channel number 26. This patch
adds support for the sensor. The raw value is read
and the temperature calculated in milli degree Celsius,
which is returned using IIO_CHAN_INFO_PROCESSED option.
