Subject: [PM8921 MFD V5 0/6] pm8921 core and subdevices
Date: Tuesday 5th April 2011 21:40:51 UTC (over 5 years ago)
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 V4 Few things have changed in kernel proper since I last sent this series -The interrupt macro names have changed (more structured)- had to update the irq patch to use the new macro names - mfd_cell does not have platfrom_data anymore - use mfd data instead. - Had a mutex_destroy in the mpp code, I had updated mpp driver to use spinlocks but that mutex_destroy was still hanging there. Removed the mutex_destroy. - since mpp code has been moved to gpio, updated the CONFIG name to reflect it is a gpio instead of a subdevice for mfd IOW use CONFIG_GPIO_PM8XXX_MPP instead of CONFIG_MFD_PM8XXX_MPP 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 MAINTAINERS | 2 + arch/arm/mach-msm/board-msm8960.c | 40 +++- arch/arm/mach-msm/include/mach/irqs-8960.h | 9 +- drivers/gpio/Kconfig | 17 + drivers/gpio/Makefile | 2 + drivers/gpio/pm8xxx-gpio.c | 455 ++++++++++++++++++++++++++++ drivers/gpio/pm8xxx-mpp.c | 325 ++++++++++++++++++++ drivers/mfd/Kconfig | 28 ++ drivers/mfd/Makefile | 2 + drivers/mfd/pm8921-core.c | 277 +++++++++++++++++ drivers/mfd/pm8xxx-irq.c | 371 +++++++++++++++++++++++ include/linux/mfd/pm8xxx/core.h | 81 +++++ include/linux/mfd/pm8xxx/gpio.h | 136 +++++++++ include/linux/mfd/pm8xxx/irq.h | 59 ++++ include/linux/mfd/pm8xxx/mpp.h | 233 ++++++++++++++ include/linux/mfd/pm8xxx/pm8921.h | 49 +++ 16 files changed, 2077 insertions(+), 9 deletions(-) create mode 100644 drivers/gpio/pm8xxx-gpio.c create mode 100644 drivers/gpio/pm8xxx-mpp.c create mode 100644 drivers/mfd/pm8921-core.c create mode 100644 drivers/mfd/pm8xxx-irq.c create mode 100644 include/linux/mfd/pm8xxx/core.h create mode 100644 include/linux/mfd/pm8xxx/gpio.h create mode 100644 include/linux/mfd/pm8xxx/irq.h create mode 100644 include/linux/mfd/pm8xxx/mpp.h create mode 100644 include/linux/mfd/pm8xxx/pm8921.h Sent by an employee of the Qualcomm Innovation Center, Inc.
