2013-02-04mfd: ab8500-debugfs: Add interrupt debugBengt Jonsson1-0/+49
This patch adds an entry in debugfs to check number of interrupts from the AB. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Bengt Jonsson <bengt.g.jonsson@stericsson.com> Reviewed-by: Rabin VINCENT <rabin.vincent@stericsson.com>
2013-02-04mfd: ab8500-debugfs: Allow number of IRQs to be provided more dynamicallyLinus Walleij1-10/+41
With the introduction of new AB* platforms, it's important to allow as much code reuse as possible. By allowing a system's number of IRQs to be dynamically passed, we can reuse almost all of the -debugfs driver.

2012-07-09mfd: Register ab8500 devices using the newly DT:ed MFD APILee Jones1-6/+0
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 Jones1-3/+3
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 Walleij1-1/+1
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>.
