0007 title: Qualcomm SPMI PMICs multi-function device
0008
0009 description: |
0010 Some Qualcomm PMICs used with the Snapdragon series SoCs are interfaced
0011 to the chip via the SPMI (System Power Management Interface) bus.
0012 Support for multiple independent functions are implemented by splitting the
0013 16-bit SPMI peripheral address space into 256 smaller fixed-size regions, 256 bytes
0014 each. A function can consume one or more of these fixed-size register regions.
0015
0016 The Qualcomm SPMI series includes the PM8941, PM8841, PMA8084, PM8998 and other
0017 PMICs. These PMICs use a "QPNP" scheme through SPMI interface.
0018 QPNP is effectively a partitioning scheme for dividing the SPMI extended
0019 register space up into logical pieces, and set of fixed register
0020 locations/definitions within these regions, with some of these regions
0021 specifically used for interrupt handling.
