eab35358aa iio: light: ROHM BH1745 colour sensor 
Add support for BH1745, which is an I2C colour sensor with red, green,
blue and clear channels. It has a programmable active low interrupt
pin. Interrupt occurs when the signal from the selected interrupt
source channel crosses set interrupt threshold high or low level.

Interrupt source for the device can be configured by enabling the
corresponding event. Interrupt latch is always enabled when setting
up interrupt.

Add myself as the maintainer for this driver in MAINTAINERS.

51b6a71689 iio: adc: ad7192: Update clock config 
There are actually 4 configuration modes of clock source for AD719X
devices. Either a crystal can be attached externally between MCLK1 and
MCLK2 pins, or an external CMOS-compatible clock can drive the MCLK2
pin. The other 2 modes make use of the 4.92MHz internal clock.

Undocumented properties adi,int-clock-output-enable and adi,clock-xtal
still supported for backward compatibility, but their use is highly
discouraged. Use cleaner alternative of configuring external clock by
using clock names mclk and xtal.

Functionality of AD7192_CLK_INT_CO will be implemented in complementary
patch by adding clock provider.

MCLK2 pins, or an external CMOS-compatible clock can drive the MCLK2
pin. The other 2 modes make use of the 4.92MHz internal clock.

To configure external clock as either a crystal or a CMOS-compatible
clock, changing the register settings is necessary. Therefore, add clock
name xtal alongside mclk. By selecting one or the other, the register is
configured.

The presence of an external clock source is optional, not required. When
both clocks and clock-names properties are present, an external clock
source is used. If the intention is to use the internal clock, both
properties should be absent. Modify required properties accordingly.

Make noa1305_measure() behave similar to noa1305_scale(), make it
assign the 'val' output variable on success and return IIO_VAL_INT.
This further simplifies noa1305_read_raw() and allows removal of
ret variable altogether.

0cef1c3232 iio: light: noa1305: Simplify noa1305_read_raw() 
The only channel this hardware supports is IIO_LIGHT, if the channel
is anything else, exit right away. The 'ret' variable is now always
only assigned by noa1305_measure(), do not initialize it anymore.
Update function parameter indent. No functional change.

26560d94d1 iio: adc: mcp3911: use devm_regulator_get_enable_read_voltage() 
This makes use of the new devm_regulator_get_enable_read_voltage()
helper function to reduce boilerplate code in the MCP3911 ADC driver.

The error message is slightly changed since there are fewer error
return paths.

An extra parameter is added to the config callback to avoid adding
state that is not used outside of the probe() function.

f2e3fbc444 iio: dac: mcp4922: drop remove() callback 
By using devm_iio_device_register(), we can drop the remove() callback
in the mcp4922 driver. We can also remove spi_set_drvdata() since there
are no more callers of spi_get_drvdata(). Also use dev_err_probe()
while we are at it.

According to the datasheet, both pressure and temperature can go up to
oversampling x32. With this option, the maximum measurement time is not
80ms (this is for press x32 and temp x2), but it is 130ms nominal
(calculated from table 3.9.2) and since most of the maximum values
are around +15%, it is configured to 150ms.
