+Subject: [PATCH] mfd: qcom-rpm: Driver for the Qualcomm RPM
+
+Driver for the Resource Power Manager (RPM) found in Qualcomm 8660, 8960
+and 8064 based devices. The driver exposes resources that child drivers
+can operate on; to implementing regulator, clock and bus frequency
+drivers.

+Subject: [PATCH] mfd: qcom_rpm: Add support for IPQ8064
+
+The IPQ8064 also includes an RPM following the same message structure as
+other chips.  In addition, it supports a few new resource types to
+support the NSS fabric clocks and the SMB208/SMB209 regulators found on
+the reference boards.

++Qualcomm Resource Power Manager (RPM)
++
++This driver is used to interface with the Resource Power Manager (RPM) found in
++various Qualcomm platforms. The RPM allows each component in the system to vote
++for state of the system resources, such as clocks, regulators and bus
++frequencies.
++
++- compatible:
++	Usage: required
++	Value type: <string>
++	Definition: must be one of:
++		    "qcom,rpm-apq8064"
++		    "qcom,rpm-msm8660"
++		    "qcom,rpm-msm8960"
++
++- reg:
++	Usage: required
++	Value type: <prop-encoded-array>
++	Definition: base address and size of the RPM's message ram
++
++- interrupts:
++	Usage: required
++	Value type: <prop-encoded-array>
++	Definition: three entries specifying the RPM's:
++		    1. acknowledgement interrupt
++		    2. error interrupt
++		    3. wakeup interrupt
++
++- interrupt-names:
++	Usage: required
++	Value type: <string-array>
++	Definition: must be the three strings "ack", "err" and "wakeup", in order
++
++- #address-cells:
++	Usage: required
++	Value type: <u32>
++	Definition: must be 1
++
++- #size-cells:
++	Usage: required
++	Value type: <u32>
++	Definition: must be 0
++
++- qcom,ipc:
++	Usage: required
++	Value type: <prop-encoded-array>
++
++	Definition: three entries specifying the outgoing ipc bit used for
++		    signaling the RPM:
++		    - phandle to a syscon node representing the apcs registers
++		    - u32 representing offset to the register within the syscon
++		    - u32 representing the ipc bit within the register

+Subject: [PATCH] regulator: qcom-rpm: Add missing state flag in call to RPM
+
+This adds the missing state parameter to the call down to the RPM. This
+is currently hard coded to the active state, as that's all we're
+supporting at this moment.

+
+The IPQ8064 also includes an RPM following the same message structure as
+other chips.  In addition, it supports a few new resource types to
+support the NSS fabric clocks and the SMB208/SMB209 regulators found on
+the reference boards.
