Andy Gross7a400582015-12-14 23:30:43 -0600[diff] [blame]3The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
4Because SMD is used as the communication transport mechanism, the RPM resides as
5a subnode of the SMD. As such, the SMD-RPM regulator requires that the SMD and
6RPM nodes be present.

70The regulator node houses sub-nodes for each regulator within the device. Each
71sub-node is identified using the node's name, with valid values listed for each
72of the pmics below.
