Merge tag 'regmap-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown: "As well as a few fixes and updates for API changes there's two new features for the API: - Better support for handling a reset of the underlying hardware, marking the register map as needing a resync to the device when we need to do that automatically - Support for querying the size and stride of the register map, allowing higher level frameworks to configure themselves more readily" * tag 'regmap-v4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Fix possible shift overflow in regmap_field_init() regmap: Fix regmap_bulk_read in BE mode regmap: kill off set_irq_flags usage regmap: irq: Fixed a typo error regmap: drop unneeded goto regmap: Introduce regmap_get_reg_stride regmap: Introduce regmap_get_max_register regmap: Use regcache_mark_dirty() to indicate power loss or reset regmap: Add a helper function for regcache sync test regmap: Constify irq_domain_ops
