I apologize for the silly question if I have overlooked something but I am looking for documentation outlining the MCA_IO pin number to the cciMX6ULsbc ADC channel number.
I see that in dey 2.0-r5 support was added for the iMX6UL ADC channels. I currently have the Digi ConnectCore 6UL Development Kit which according to the documentation supports five ADC channels on the following Microcontroller Assist (MCA) IO pins: MCA_IO0, MCA_IO1, MCA_IO3, MCA_IO4, and MCA_IO5.
I am looking to test the ADCs on my developments kit and I want to know the channel mapping from the MCA_IO pin to the ADC channel mapping in arch/arm/boot/dts/imx6ul-ccimx6ulsbc-id135.dts. I am assuming it is not 1 to 1 because the default channels are 2,3, and 5 in that file but I could be wrong. Any guidance or documentation would be greatly appreciated.
