ADC sample captures take a certain amount of time to complete after initiated; this conversion time range can be anywhere from 5 microseconds to 53.68 seconds depending on the configuration of the Analog Input Frame Timer register. When the conversion is in progress, the ADC Status register CNV bit is high. Call regmap_read_poll_timeout() to poll until the ADC conversion is completed (or timeout if more than 53.68 seconds passes).
