Subject: [PM8921 MFD V4 0/6] pm8921 core and subdevices
Date: Thu, 17 Mar 2011 21:21:52 -0700 [thread overview]
Message-ID: <1300422118-13888-1-git-send-email-adharmap@codeaurora.org> (raw)
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.
Updates from V3:
cleanup irq driver's local storage, Thomas Glexiner pointed out the remnants
cleanup the copyright comments, suggested by Grant Likely
move the mpp code from drivers/mfd to drivers/gpio
Abhijeet Dharmapurikar (5):
mfd: pm8921: Add PMIC 8921 core driver
mfd: pm8xxx: Add irq support
gpio: pm8xxx-gpio: Add pm8xxx gpio driver
MAINTAINERS: Add patterns for pmic 8921 files to MSM subsystem
msm: board-8960: Add support for pm8921
David Collins (1):
mfd: pm8xxx-mpp: Add pm8xxx MPP driver
