Merge tag 'regmap-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "A quiet release for regmap, some cleanups, fixes and:

   - Improved node coalescing for rbtree, reducing memory usage and
     improving performance during syncs.
   - Support for registering multiple register patches.
   - A quirk for handling interrupts that need to be clear when masked
     in regmap-irq"
