MFC r266960:
Configure the analog input 7 which, on BBB, is connected to the 3V3B rail through a voltage divisor (R163 and R164 on page 4 of BBB schematic). Add a note about this on ti_adc(4) man page. The ti_adc(4) man page will first appear on 10.1-RELEASE. Suggested by: Sulev-Madis Silber (ketas) Manual page reviewed by: brueffer (D127)
