Javier Carrasco ccc26bd7d7 iio: light: veml6030: add support for veml6035 
The veml6035 is an ALS that shares most of its functionality with the
veml6030, which allows for some code recycling.

Some chip-specific properties differ and dedicated functions to get and
set the sensor gain as well as its initialization are required.

Javier Carrasco f1bfc1c993 dt-bindings: iio: light: veml6030: add veml6035 
The veml6035 is a similar ambient light sensor to the veml6030, and
from the bindings point of view, it shares the same properties. Its
only difference in that respect is a different I2C address.

Estend the existing bindings to support the veml6035 ALS.

Javier Carrasco e980726d89 iio: light: veml6030: power off device in probe error paths 
Move devm_add_action_or_reset() with a device shut down action to the
hardware initialization function to ensure that any error path after
powering on the device leads to a power off. Add struct device *dev
to the argument list to clarify the device the action is registered
against, and use it wherever &client->dev was used.

Javier Carrasco ed59fc90f3 iio: light: veml6030: drop processed info for white channel 
The resolution of the WHITE channel is not provided by the manufacturer,
neither in the datasheet nor in the application note (even their
proprietary application only processes the ALS channel, giving raw
values for WHITE).

The current implementation assumes that both resolutions are identical,
which is extremely unlikely, especially for photodiodes with different
spectral responses.

Drop the processed information as it is meaningless.

Javier Carrasco 8ff21dd6df iio: light: veml6030: use read_avail() for available attributes 
Drop custom attributes by using the standard read_avail() callback to
read scale and integration time. When at it, add the integration time
and scale attributes fro the WHITE channel, as they modify its value as
well. To avoid breaking the current ABI, these attributes must be kept
as separate for both channels even though they are shared under the
hood.

Javier Carrasco c61d687cd5 iio: light: veml6030: add set up delay after any power on sequence 
The veml6030 requires a delay of 4 ms after activating the sensor. That
is done correctly during the hw initialization, but it's missing after
resuming.

Move the delay to the power on function to make sure that it is always
observerd. When at it, use fsleep() instead of usleep_range() as such a
narrow range is not required.

Vasileios Amoiridis 1960713218 iio: pressure: bmp280: Use char instead of s32 for data buffer 
As it was reported and discussed here [1], storing the sensor data in an
endian aware s32 buffer is not optimal. Advertising the timestamp as an
addition of 2 s32 variables which is also implied is again not the best
practice. For that reason, change the s32 sensor_data buffer to a u8
buffer and align it properly.

Javier Carrasco 0c78543660 iio: adc: sun20i-gpadc: use scoped device_for_each_child_node() 
Switch to device_for_each_child_node_scoped() to simplify the code by
removing the need for calls to fwnode_handle_put() in the error path.

This prevents possible memory leaks if new error paths are added without
the required call to fwnode_handle_put().

Uwe Kleine-König ee3bf0c148 iio: adc: ti-ads1119: Drop explicit initialization of struct i2c_device_id::driver_data to 0 
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Alexandru Ardelean f3838e934d iio: adc: ad7606: add support for AD7606C-{16,18} parts 
The AD7606C-16 and AD7606C-18 are pretty similar with the AD7606B.
The main difference between AD7606C-16 & AD7606C-18 is the precision in
bits (16 vs 18).
Because of that, some scales need to be defined for the 18-bit variants, as
they need to be computed against 2**18 (vs 2**16 for the 16 bit-variants).

Because the AD7606C-16,18 also supports bipolar & differential channels,
for SW-mode, the default range of 10 V or ±10V should be set at probe.
On reset, the default range (in the registers) is set to value 0x3 which
corresponds to '±10 V single-ended range', regardless of bipolar or
differential configuration.

Aside from the scale/ranges, the AD7606C-16 is similar to the AD7606B.

The AD7606C-18 variant offers 18-bit precision. Because of this, the
requirement to use this chip is that the SPI controller supports padding
of 18-bit sequences to 32-bit arrays.
