Merge: e86328c d4a1a31

    Merge tag 'regmap-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
    
    Pull regmap updates from Mark Brown:
     "Quite a few new features for regmap this time, mostly expanding things
      around the edges of the existing functionality to cover more devices
      rather than thinsg with wide applicability:
    
       - Support for offload of the update_bits() operation to hardware
         where devices implement bit level access.
       - Support for a few extra operations that need scratch buffers on
         fast_io devices where we can't sleep.
       - Expanded the feature set of regmap_irq to cope with some extra
         register layouts.
       - Cleanups to the debugfs code"
    
    * tag 'regmap-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
      regmap: Allow installing custom reg_update_bits function
      regmap: debugfs: simplify regmap_reg_ranges_read_file() slightly
      regmap: debugfs: use memcpy instead of snprintf
      regmap: debugfs: use snprintf return value in regmap_reg_ranges_read_file()
      regmap: Add generic macro to define regmap_irq
      regmap: debugfs: Remove scratch buffer for register length calculation
      regmap: irq: add ack_invert flag for chips using cleared bits as ack
      regmap: irq: add support for chips who have separate unmask registers
      regmap: Allocate buffers with GFP_ATOMIC when fast_io == true
