Merge tag 'regmap-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap

Pull regmap updates from Mark Brown:
 "There's no real overall theme to the regmap changes for this release,
  it's a collection of individual features.  The main bits are:

   - Support for 64 bit registers, mainly for MMIO use, from Xiubo Li.

   - Support for trigger type configuration for regmap-irq from Laxman
     Dewangan.

   - Use native physical I/O for MMIO register maps to avoid confusion
     with the conversions that readl() and writel() do to little endian
     on big endian systems (with some DT updates to fix some workarounds
     people were doing), code from Simon Arlott.

   - Use a binary search rather than iteraton to improve the runtime
     performance of the rbtree code from Nikesh Oswal"

* tag 'regmap-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
  regmap: debugfs: Use seq_file for the access map
  regmap: irq: add support for configuration of trigger type
  regmap: use IS_ALIGNED instead of % to improve the performance
  regmap: cache: Move the num_reg_defaults check as early as possible
  regmap: cache: Add warning info for the cache check
  regmap: missing case statement
  regmap: shift wrapping bugs in 64 bit code
  regmap: cache: Add 64-bit mode support
  regmap: cache: To suppress the noise of checkpatch
  regmap: fix the warning about unused variable
  regmap: add 64-bit mode support
  regmap: mmio: Add regmap_mmio_get_min_stride
  regmap: mmio: remove the useless code
  regmap: Fix leftover from struct reg_default to struct reg_sequence change
  regmap: replace kmalloc with kmalloc_array
  regmap: replace kzalloc with kcalloc
  regmap: rbtree: When adding a reg do a bsearch for target node
  regmap-mmio: Use native endianness for read/write
