[PATCH v2 0/4] Adding scale support to the lpc32xx ADC driver

[Gregory CLEMENT <gregory.clement@bootlin.com>]

Hello,

This is the second version of a series adding the support of the scale
feature to the lpc32xx ADC driver. In order to use it we need to have
the voltage reference as a device tree property, however in order to
be backward compatible, this property is optional and do not prevent
to use the driver if missing.

I updated the binding documentation accordingly.

Gregory

Changelog:
v1 -> v2:

 - "dt-bindings: iio: adc: move lpc32xx-adc out of staging" and
   "iio:adc:lpc32xx use SPDX-License-Identifier" has been merged

 - split "iio:adc:lpc32xx use SPDX-License-Identifier" in 2 patches
   one foe sorting and the second one for removal

 - add reviewed-by from Rob Herring on the binding documentation patch

 - add default in the switch/case in lpc32xx_read_raw()

 - no more use scan_type.realbits and directly put the value in the
   IIO_CHAN_INFO_SCALE case

 - keep the const for the struct iio_chan_spec and declare 2 of them.

 - remove the unrelated and bad whitespace change.
