Merge tag 'regmap-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown: "In user visible terms just a couple of enhancements here, though there was a moderate amount of refactoring required in order to support the register cache sync performance improvements. - Support for block and asynchronous I/O during register cache syncing; this provides a use case dependant performance improvement. - Additional debugfs information on the memory consuption and register set" * tag 'regmap-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: (23 commits) regmap: don't corrupt work buffer in _regmap_raw_write() regmap: cache: Fix format specifier in dev_dbg regmap: cache: Make regcache_sync_block_raw static regmap: cache: Write consecutive registers in a single block write regmap: cache: Split raw and non-raw syncs regmap: cache: Factor out block sync regmap: cache: Factor out reg_present support from rbtree cache regmap: cache: Use raw I/O to sync rbtrees if we can regmap: core: Provide regmap_can_raw_write() operation regmap: cache: Provide a get address of value operation regmap: Cut down on the average # of nodes in the rbtree cache regmap: core: Make raw write available to regcache regmap: core: Warn on invalid operation combinations regmap: irq: Clarify error message when we fail to request primary IRQ regmap: rbtree Expose total memory consumption in the rbtree debugfs entry regmap: debugfs: Add a registers `range' file regmap: debugfs: Simplify calculation of `c->max_reg' regmap: cache: Store caches in native register format where possible regmap: core: Split out in place value parsing regmap: cache: Use regcache_get_value() to check if we updated ...
