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.
