Command DB is a simple database in the shared memory of QCOM SoCs, that provides information regarding shared resources. Some shared resources in the SoC have properties that are probed dynamically at boot by the remote processor. The information pertaining to the SoC and the platform are made available in the shared memory. Drivers can query this information using predefined strings.

resources. Platform drivers that require to set state of a shared

If you say yes to this option, support will be included for the

|
Resource Power Manager system found in the Qualcomm 8974 based
|
|
devices.

This is required to access many regulators, clocks and bus

Say M here if you want to include support for the Qualcomm RPM as a
