4 Subject: clk: qcom: Add support for RPM Clocks
5
6 This adds initial support for clocks controlled by the Resource
7 Power Manager (RPM) processor on some Qualcomm SoCs, which use
8 the qcom_rpm driver to communicate with RPM.
9 Such platforms are apq8064 and msm8960.

44 + The RPM (Resource Power Manager) is a dedicated hardware engine for
45 + managing the shared SoC resources in order to keep the lowest power
