Merge tag 'regmap-v4.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap 

Pull regmap fixes from Mark Brown:
 "A few things here:

   - a change from Lars to fix insertion of cache values at the start of
     rather than end of a rbtree block.  This hadn't been noticed before
     since almost everything lists registers in ascending order.

   - a fix from Takashi for spurious warnings during cache sync with
     read once registers, a problem which can be very noticeable on
     devices that it affects.

   - a fix from Valentin for a tighening of the oneshot IRQ request
     interface which would have broken affected devices"
