2012-01-09mfd: Unify abx500 headers in mfd/abx500Linus Walleij3-310/+0
This moves all the header files related to the abx500 family into a common include directory below mfd. From now on we place any subchip header in that directory. Headers previously in e.g. <linux/mfd/ab8500/gpio.h> get prefixed and are now e.g. <linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface remains in <linux/mfd/abx500.h>.

2011-10-24mfd: Refactor ab8500 GPADC API, add raw accessKarl Komierowski1-1/+4
Refactor the GPADC interface to avoid bugs in calling code: - ab8500_gpadc_[convert|read_raw|ad_to_voltage] clarifies each functions use case, *convert wraps *read_raw, and we can access raw ADC values properly. - Renamed gpadc function arguments from "input" to "channel" to clarify use, so we don't get confused again.

2011-03-28gpio: driver for 42 AB8500 GPIO pinsBibek Basu1-0/+21
To get rid of port expanders, the free GPIOs of ab8500 can be used. There are 42 GPIO pins. Out of which 16 are interrupt capable.This patch implements 16 virtual IRQ mapped to 16 interrupt capable AB8500 GPIOs.

Rename AB8500 GPADC header so as not to be redunantly named. Signed-off-by: Linus Walleij <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-03-23mfd: Reentrance and revamp ab8500 gpadc fetching interfaceDaniel Willerud1-1/+5
This revamps the interface so that AB8500 GPADCs are fetched by name. Probed GPADCs are added to a list and this list is searched for a matching GPADC. This makes it possible to have multiple AB8500 GPADC instances instead of it being a singleton, and rids the need to keep a GPADC pointer around in the core AB8500 MFD struct. Currently the match is made to the device name which is by default numbered from the device instance such as "ab8500-gpadc.0" but by using the .init_name field of the device a more intiutive naming for the GPADC blocks can be achieved if desired.

2011-03-23mfd: Move ab8500 gpadc header to subdirDaniel Willerud1-0/+28
This moves the ab8500-gpadc.h header down into the ab8500/ subdir in include/linux/mfd and fixes some whitespace in the header in the process. Signed-off-by: Daniel Willerud <[email protected]> Signed-off-by: Linus Walleij <[email protected]> Signed-off-by: Samuel Ortiz <[email protected]>
2011-03-23mfd: AB8500 system control driverMattias Nilsson1-0/+254
This adds a pretty straight-forward system control driver for the AB8500. This driver will be used from the core platform, e.g the clock tree implementation in the machine code, and is by nature singleton. There are a few simple functions to read, write, set and clear registers so that the machine code can control its own foundation.
