 regmap: Updates for 3.5
 
 A surprisingly large series of updates for regmap this time, mostly due
 to all the work Stephen Warren has done to add support for MMIO buses.
 This wasn't really the target for the framework but it turns out that
 there's a reasonable number of cases where it's very helpful to use the
 register cache support to allow the register map to remain available
 while the device is suspended.
 
 - A MMIO bus implementation, contributed by Stephen Warren. Currently this
   is limited to 32 bit systems and native endian registers.
 - Support for naming register maps, mainly intended for MMIO devices with
   multiple register banks. This was also contributed by Stephen Warren.
 - Support for register striding, again contributed by Stephen Warren and
   mainly intended for use with MMIO as typically the registers will be a
   fixed size but byte addressed.
 - irqdomain support for the generic regmap irq_chip, including support
   for dynamically allocate interrupt numbers.
 - A function dev_get_regmap() which allows frameworks using regmap to
   obtain the regmap for a device from the struct device, making life a
   little simpler for them.
 - Updates to regmap-irq to support more chips (contributed by Graeme
   Gregory) and to use irqdomains.
 - Support for devices with 24 bit register addresses.
 
 The striding support collided with all the topic branches so the
 branches look a bit messy and eventually I just gave up.  There's also
 the TI Palmas driver and a couple of other isolated MFD patches that
 all depend on new regmap features so are being merged here.
