Subject: [PATCH 0/2] Add SAW support to QCOM SPMI driver

The SAW is the “Subsystem Power Manager (SPM),
Adaptive Voltage Scaling (AVS)
and Dynamic Current Management (DCM) Wrapper”,
that is, a core that contains logic to implement the SPM, AVS,
and DCM functions. The SAW manages power controls for a client core
such as a CPU.

The PMIC regulators supplying power to the CPU cores should not
be controlled by the SPMI accesses directly, but through the SAW
interface.

The patch series adds SAW support to the SPMI regulator driver.
The special SAW controlled regulators should be configured by
device tree handle. The SPI driver will handle those regulators
separately through the SAW interface, instead of SPMI.
