Hello,
I would like to test all four ADC channels (ADC_D, ADC_C, ADC_B, ADC_A) of the efusA9X module. So far I checked the adc example and the device tree. According to the example the ADC will be handled via device files (/dev/mvf_adc.?). But I could not find these in the sysfs. [1] and [2] shows some device tree nodes. [2] tells me that the ADCs are already in use for some other functions. But [1] does not create the missing decive files in the sysfs.
What I am missing is a example of a device tree node to inform the kernel about the ADCs. Is there already an example for this or how do I get the device files into the sysfs?
