Description

测试步骤：
1、A/I接口测试，INI1、2、3、4不接任何直流电压源；
2、使用以下命令，分别查看adc的值
cat /sys/devices/platform/fec10000.saradc/iio:device0/in_voltage2_raw
cat /sys/devices/platform/fec10000.saradc/iio:device0/in_voltage4_raw
cat /sys/devices/platform/fec10000.saradc/iio:device0/in_voltage6_raw
cat /sys/devices/platform/fec10000.saradc/iio:device0/in_voltage7_raw
3、得到相应值其应满足无限接近0

实际测试结果：

期望结果：得到相应值其应满足无限接近0
