description: |
rpmh-regulator devices support PMIC regulator management via the Voltage
Regulator Manager (VRM) and Oscillator Buffer (XOB) RPMh accelerators.
The APPS processor communicates with these hardware blocks via a
Resource State Coordinator (RSC) using command packets. The VRM allows
changing three parameters for a given regulator, enable state, output
voltage, and operating mode. The XOB allows changing only a single
parameter for a given regulator, its enable state. Despite its name,
the XOB is capable of controlling the enable state of any PMIC peripheral.
It is used for clock buffers, low-voltage switches, and LDO/SMPS regulators
which have a fixed voltage and mode.
=======================
Required Node Structure
=======================
RPMh regulators must be described in two levels of device nodes. The first
level describes the PMIC containing the regulators and must reside within an
RPMh device node. The second level describes each regulator within the PMIC
which is to be used on the board. Each of these regulators maps to a single
RPMh resource.
The names used for regulator nodes must match those supported by a given
PMIC. Supported regulator node names are
