The Qualcomm PMIC Arbiter, in addition to being a basic SPMI controller, also implements interrupt handling for slave devices. Note, this is outside the scope of SPMI, as SPMI leaves interrupt handling completely unspecified. Extend the driver to provide a irq_chip implementation and chained irq handling which allows for these interrupts to be used.

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.
