  21 +Qualcomm Resource Power Manager (RPM)
  22 +
  23 +This driver is used to interface with the Resource Power Manager (RPM) found in
  24 +various Qualcomm platforms. The RPM allows each component in the system to vote
  25 +for state of the system resources, such as clocks, regulators and bus
  26 +frequencies.
  27 +
  28 +- compatible:
  29 +       Usage: required
  30 +       Value type: <string>
  31 +       Definition: must be one of:
  32 +                   "qcom,rpm-apq8064"

  36 +- reg:
  37 +       Usage: required
  38 +       Value type: <prop-encoded-array>
  39 +       Definition: base address and size of the RPM's message ram
  40 +
  41 +- interrupts:
  42 +       Usage: required
  43 +       Value type: <prop-encoded-array>
  44 +       Definition: three entries specifying the RPM's:
  45 +                   1. acknowledgement interrupt
  46 +                   2. error interrupt
  47 +                   3. wakeup interrupt

  49 +- interrupt-names:
  50 +       Usage: required
  51 +       Value type: <string-array>
  52 +       Definition: must be the three strings "ack", "err" and "wakeup", in order
  53 +
  54 +- #address-cells:
  55 +       Usage: required
  56 +       Value type: <u32>
  57 +       Definition: must be 1
  58 +
  59 +- #size-cells:
  60 +       Usage: required
  61 +       Value type: <u32>
  62 +       Definition: must be 0
  63 +
  64 +- qcom,ipc:
  65 +       Usage: required
  66 +       Value type: <prop-encoded-array>
  67 +
  68 +       Definition: three entries specifying the outgoing ipc bit used for
  69 +                   signaling the RPM:
  70 +                   - phandle to a syscon node representing the apcs registers
  71 +                   - u32 representing offset to the register within the syscon
  72 +                   - u32 representing the ipc bit within the register
