+
+The IPQ8064 also includes an RPM following the same message structure as

+support the NSS fabric clocks and the SMB208/SMB209 regulators found on
+the reference boards.

+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.
