[PATCH v4 09/15] iio: adc: axp20x_adc: Replace adc_en2 flag with adc_en2_mask field

Aidan MacDonald
2022-06-29T14:30:32Z

The adc_en2 flag is essentially specific to axp20x-compatible devices
because it hardcodes register values. Replace it with a mask field
so the register value can be specified in device match data.
