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.
