From: Abhijeet Dharmapurikar <adharmap@xxxxxxxxxxxxxx> This patch series adds support for pmic 8921 chip and its subdevices. The pmic 8921 chip is used as a power management ic for 8960 based boards. It communicates over the ssbi bus, ssbi bus can be found here https://patchwork.kernel.org/patch/601771/ The patch set contains support for interrupt, gpio and mpp (multi purpose pin) subdevices. Note that gpio and mpp subdevices need the interrupt subdevice to be operational, this is becuase the reading the the value of gpio/mpp lines happens by doing a transaction over registers managed by the interrupt subdev. The code invokes a call on interrupt subdevice, rather than writing to those registers directly, avoiding race conditions.
