The TPS2511 integrates this DCP_Auto functionality which allows for it to charge BC1.2 compliant devices as well as non-compliant devices. The sequence is outlined within 7. 4.2 of the TPS2511 datasheet, but the TPS2511 starts by advertising the non-compliant charging scheme of Divider 2, which puts 2.7V on the DP pin and 2V on the DM pin.
