The NPCM ADC is a 10-bit converter for eight channel inputs. The NPCM ADC driver tested on NPCM750 evaluation board. Addressed comments from:. - Jonathan Cameron: https://lore.kernel.org/patchwork/patch/1030483/ Changes since version 2: - Return error if clock have not found in the device tree ADC node. - Modify regulator order for avoid mixing devm and non-devm path. - Modify probe and remove function to have relative ordering. 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.
