2013-02-04mfd: ab8500-debugfs: Export all AB8500 ADCs as debugfs nodesJohn Beckett
Allow a user to take a glimpse into the inner workings of the AB8500 Analogue-to-Digital Converters, via debugfs. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: John Beckett <john.beckett@stericsson.com> Reviewed-by: Mattias WALLIN <mattias.wallin@stericsson.com>
2013-02-04mfd: ab8500-debugfs: Formated access AB8500 registers from debugfs entrycarriere etienne
Add debugfs entry ab8500/hwreg to read/write bit-field in AB8500 registers.

2013-02-04mfd: ab8500-debugfs: Use NULL to initialise remaining NULL pointerLee Jones
Partly for coding style reasons, but mostly because sparse warns on it. This patch is a completion of a previous patch by Mark Brown. Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2012-07-09mfd: Register ab8500 devices using the newly DT:ed MFD APILee Jones
Now the MFD API is Device Tree aware we can use it for platform registration again, even when booting with DT enabled. To aid in Device Node pointer allocation we provide each cell with the associative compatible string.

2012-07-09mfd: Generically describe interactions with the DB8500 PRCMULee Jones
There is only one method used to communicate with the DB8500 PRCMU, via I2C. Now this can be assumed, there is no requirement to specify the protocol in the function name. This patch removes protocol specifics and uses a more generic naming convention. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-01-09mfd: Unify abx500 headers in mfd/abx500Linus Walleij
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>.

2011-10-31mfd: Add module.h to the implicit drivers/mfd usersPaul Gortmaker

2011-07-31mfd: Use kstrtoul_from_user in ab8500Peter Huewe
This patch replaces the code for getting an unsigned long from a userspace buffer by a simple call to kstroul_from_user. This makes it easier to read and less error prone. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2010-10-29mfd: AB8500 debugfsMattias Wallin
This patch adds the possibility to read and write registers via the debug_fs. It also adds ranges of registers sorted by bank which makes it possible to read all defined registers in a bank.
