* mfd: Remove wm8400 custom cache implementationMark Brown2012-05-20
| | | | | | | | | | Save a useful amount of code by removing the custom cache implementation for wm8400 and using the regmap cache. Also simplify things by not separately reseting the CODEC registers, this is a sufficiently infrequent operation that we can simply invalidate the entire cache when this happens.

* mfd: Define all twl-regulator feature flags in one placeNeilBrown2012-05-20
| | | | | | | | | | | | twl-regulator has a collection of feature flags, some defined in twl-core.c and one defined in i2c/twl.h. This is confusing for anyone adding a new feature flag. So collect them together and place them in twl.h immediately after the structure in which they are initially set.

With the current implementation, when an ab9540 interrupt occurs, 17 Latch registers are read through i2c. With hierarchical interrupt implementation, there are only 4 i2c accesses.

* mfd: Fix wm831x register range passing for recent ARM updatesMark Brown2012-05-07
| | | | | | | | | | | | | | | 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.
