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 |
|
For PM6150, smps1 - smps5, ldo1 - ldo19 |
|
For PM6150L, smps1 - smps8, ldo1 - ldo11, bob |
