| 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 |
| For PM6150, smps1 - smps5, ldo1 - ldo19 |
| For PM6150L, smps1 - smps8, ldo1 - ldo11, bob |
| For PM6350, smps1 - smps5, ldo1 - ldo22 |
