Merge tag 'regulator-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
"The biggest set of changes in here is the addition of the Qualcomm
RPMH driver. As well as the regualtor driver itself being quite large
due to the usual involved Qualcomm regulator stuff there's also some
code shared with the arm-soc tree, a bus driver required to
communicate with the hardware that actually winds up being much larger
than the regulator driver itself and a LLCC driver that was part of
the same signed tag used with the arm-soc tree.
Other than that it's a fairly standard and quiet release, highlights
include:
- Addition of device links from regulator consumers to their
regulators, helping the core avoid dependency issues during
suspend.
- Support for the entertainingly innovative suspend implementation in
the BD9571MWV.
- Support for switch regulators on the PFUZE100, this required two
goes due to backwards compatibility issues with old DTs that were
discovered.
- Support for Freescale PFUZE3001 and SocioNext UniPhier.
- The aforementioned Qualcomm RPMH driver together with the driver
changes required to support it"
