Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and is used to communication with one or more PMIC (slave) devices on the SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the SPMI controller that provides concurrent and autonomous PMIC access to various entities that need to communicate with the PMIC. The SPMI controller hardware handles all of the SPMI bus activity (bus arbitration, sequence start condition, transmission of frames, etc). This software driver uses the PMIC Arbiter register interface to initiate command sequences on the SPMI bus. The status register is read to determine when the command sequence has completed and whether or not it completed successfully.

If you say yes to this option, support will be included for the
|
|
built-in SPMI PMIC Arbiter interface on Qualcomm MSM family
|
|
processors.
|
|
|
|
This is required for communicating with Qualcomm PMICs and
|
|
other devices that have the SPMI interface.
