7title: Qualcomm SPMI PMICs multi-function device
8
9description: |
10  Some Qualcomm PMICs used with the Snapdragon series SoCs are interfaced
11  to the chip via the SPMI (System Power Management Interface) bus.
12  Support for multiple independent functions are implemented by splitting the
13  16-bit SPMI peripheral address space into 256 smaller fixed-size regions, 256 bytes
14  each. A function can consume one or more of these fixed-size register regions.
15
16  The Qualcomm SPMI series includes the PM8941, PM8841, PMA8084, PM8998 and other
17  PMICs.  These PMICs use a "QPNP" scheme through SPMI interface.
18  QPNP is effectively a partitioning scheme for dividing the SPMI extended
19  register space up into logical pieces, and set of fixed register
20  locations/definitions within these regions, with some of these regions
21  specifically used for interrupt handling.
