Pull regmap updates from Mark Brown:
 "The main thing this time around has been some improvments to async
  I/O.

   - Cleaned up the async I/O support and extended it to allow single
     register writes more easily.  This is now used where possible for
     internally generated I/O, providing performance improvements for
     devices that can do async I/O.
   - An API for issuing a sequence of register writes as a single
     operation.  Some devices and buses can take advantage of this to do
     the I/O faster.
   - Addition of regmap_field APIs which help drivers for devices with
     repeated IPs or which move registers around between revisions to
     share helpers.
   - Support for SPMI buses"
