[Patch v3 00/10] Add RPM/SMD Support for QCOM platforms

[Patch v3 00/10] 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.

Changes since v2:
  - Fixed some missed review comments
  - Corrected the SMD RPM example binding indentation

Changes since v1:
  - Fixed various review comments
  - Removed MSM8974 patches as there was already an outstanding patch

[Patch v3 01/10] 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.
