title: Qualcomm SPMI PMICs multi-function device
description: |
Some Qualcomm PMICs used with the Snapdragon series SoCs are interfaced
to the chip via the SPMI (System Power Management Interface) bus.
Support for multiple independent functions are implemented by splitting the
16-bit SPMI peripheral address space into 256 smaller fixed-size regions, 256 bytes
each. A function can consume one or more of these fixed-size register regions.
The Qualcomm SPMI series includes the PM8941, PM8841, PMA8084, PM8998 and other
PMICs. These PMICs use a "QPNP" scheme through SPMI interface.
QPNP is effectively a partitioning scheme for dividing the SPMI extended
register space up into logical pieces, and set of fixed register
locations/definitions within these regions, with some of these regions
specifically used for interrupt handling.
