[PATCH 00/11] Add RPM/SMD Support for QCOM platforms

[PATCH 00/11] Add RPM/SMD Support for QCOM platforms

[Andy Gross]

This patch set cleans up the documentation that is currently in place for the
SMD, SMD-RPM, and SMD-RPM regulators.  In addition, this patch set adds support
for the PM8916 found on MSM8916 platforms and the PMA8084 found on APQ8084
platforms.

All of the relevant DTS information is fleshed out for the regulators and their
dependencies for all of the platforms which support SMD-RPM regulators.

[PATCH 01/11] soc: qcom: documentation: Update SMD/RPM Docs

[Andy Gross]

This patch moves the qcom,smd-rpm.txt to the correct location and splits
out the smd and rpm documentation.  In addition, a smd-rpm-regulator
document is added.

+QCOM SMD RPM REGULATOR
+
+The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
+Because SMD is used as the communication transport mechanism, the RPM resides as
+a subnode of the SMD.  As such, the SMD-RPM regulator requires that the SMD and
+RPM nodes be present.
+
+Please refer to the qcom,smd.txt for information pertaining to the SMD node.
