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.

Subject: [PATCH] regulator: rpm: add support for RPM-controller SMB208
|
||||||
|
|
||||||
|
The IPQ8064 reference boards make use of SMB208 regulators which are
|
||||||
|
controlled by RPM. Implement support for these regulators in the RPM
|
||||||
|
regulator driver.

This adds the missing state parameter to the call down to the RPM. This

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.
