  24 +Qualcomm Resource Power Manager (RPM)
  25 +
  26 +This driver is used to interface with the Resource Power Manager (RPM) found in
  27 +various Qualcomm platforms. The RPM allows each component in the system to vote
  28 +for state of the system resources, such as clocks, regulators and bus
  29 +frequencies.
