How can I connect the multiplexer output (MUX_OUT) of the TPS65217 to the ADC channels of the AM3358?

The MUX_OUT pin of the PMIC (TPS65217C) can be connected to the ADC channels of the AM335x externally on the OSD335x-SM device. The ball numbers for each of the PMIC_MUX pins and commonly used ADC channel are given below:

But, OSD335x (OSD3358-BAS) DOES NOT support this functionality since MUX_IN and MUX_OUT pins are not externally accessible on this device.
