mfd: Add wm8994 register access and default information Describe the register map to the regmap core so that we can use its diagnostic features and cache support. This is split out from the patch using it due to the size so that the actual code change is a bit clearer. As the various devices are supersets of each other the access maps are built up by layering the functions on top of each other, though the interface for specifying the register defaults isn't currently amenable to this.

device.h: cleanup users outside of linux/include (C files) For files that are actively using linux/device.h, make sure that they call it out. This will allow us to clean up some of the implicit uses of linux/device.h within include/* without introducing build regressions. Yes, this was created by "cheating" -- i.e. the headers were cleaned up, and then the fallout was found and fixed, and then the two commits were reordered. This ensures we don't introduce build regressions into the git history. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

mfd: wm8994: Update to use maple tree register cache The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the wm8994 driver to use the more modern data structure.

This is split out from the patch using it due to the size so that the actual code change is a bit clearer. As the various devices are supersets of each other the access maps are built up by layering the functions on top of each other, though the interface for specifying the register defaults isn't currently amenable to this.

mfd: Mark WM1811 GPIO6 register volatile for later revisions For later chip revisions the WM1811 GPIO6 register is always volatile so store the device revision when initialising the driver and then check at runtime if we're running on a newer device.

mfd: wm8994: Update to use maple tree register cache The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the wm8994 driver to use the more modern data structure.

mfd: Initialise WM8994 register cache after reading chip ID registers The different devices handled by the WM8994 can be distinguished using their ID registers so we don't need to rely on the user having registered the device correctly. Instead do the initial regmap setup with a minimal configuration only supporting physical I/O and then configure the cache once we have identified the device.
