This patch set adds Analog-to-Digital Converter (ADC) support 
for the Nuvoton NPCM Baseboard Management Controller (BMC).

The NPCM ADC is a 10-bit converter for eight channel inputs.

The NPCM ADC driver tested on NPCM750 evaluation board.

Addressed comments from:.
 - Peter Meerwald-Stadler: https://www.spinics.net/lists/linux-iio/msg42159.html
 - Jonathan Cameron: https://www.spinics.net/lists/linux-iio/msg42183.html
				  
Changes since version 1:
 - Add NPCM prefix.
 - Remove unnecessary parameter initialization.
 - Modify read function to avoid racy condition.
 - Reading the reference voltage when needed.
 - Modify dt-binding documentation according Jonathan comments.
