Merge tag 'regulator-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"This has been a fairly quiet release for the regulator API, the main
thing has been the addition of helpers for interrupt handling from
Matti Vaittinen.
We do also have support for quite a few new devices.
Summary:
- Helpers for trivial interrupt notifications, making it easier for
drivers to handle error interrupts.
- Support for Dialog DA914x, Maxim MAX2008x, Qualcomm PM8826,
PMG1100, and PM8450 and TI TPS68470"
