2013-04-08mfd: 88pm860x: Drop devm_kfree of devm_kzalloc'd dataJingoo Han
devm_kfree() allocates memory that is released when a driver detaches. Thus, there is no reason to explicitly call devm_kfree() in probe or remove functions. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

commit 0848c94fb4 ("mfd: core: Push irqdomain mapping out into devices") that appeared in v3.6-rc6 adds another argument to the mfd_add_devices() call, and that makes commit a830d28b48bf ("power_supply: Enable battery-charger for 88pm860x", which is battery tree) no longer compatible with the latest kernels.

2012-09-15mfd: core: Push irqdomain mapping out into devicesMark Brown
Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver.

2012-09-11mfd: 88pm860x: Move _IO resources out of ioport_ioresourceMark Brown
The removal of mach/io.h from most ARM platforms also set the range of valid IO ports to be empty for most platforms when previously any 32 bit integer had been valid. This makes it impossible to add IO resources as the added range is smaller than that of the root resource for IO ports. Since we're not really using IO memory at all fix this by defining our own root resource outside the normal tree and make that the parent of all IO resources. This also ensures we won't conflict with read IO ports if we ever run on a platform which happens to use them.
