make BOARD=t31_lite br-all

or change br-ext-chip-ingenic/board/t31/kernel/t31.generic.config before building

- # CONFIG_MFD_JZ_SADC_V13 is not set
- # CONFIG_MFD_JZ_SADC_AUX is not set

-O - turn on night mode when ADC value drops below this threshold
-F - turn off night mode when ADC value goes above this threshold

Need to choose the correct default values of thresholdOn and thresholdOff
