In some scenarios the early stages of the boot chain has configured regulators to be in a required state, but the later stages has skipped to inform the RPM about it's requirements. But as the SMD RPM regulators are being initialized voltage change requests will be issued to align the voltage with the valid ranges. The RPM aggregates all parameters for the specific regulator, the voltage will be adjusted and the "enabled" state will be "off" - and the regulator is turned off. This patch addresses this problem by caching the requested enable state, voltage and load and send the parameters in a batch, depending on the enable state - effectively delaying the voltage request for disabled regulators.
