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"
