744ef9b091 regulator: Update DA9121 dt-bindings
Update bindings for the Dialog Semiconductor DA9121 voltage regulator to
add device variants.
Because several variants have multiple regulators, and to regard potential
to add GPIO support in future, the 'regulators' sub-node is added,
following the precedent set by other multi-regulator devices, including
the DA9211 family. This breaks compatibility with the original submission
by Vincent Whitchurch - but as this is still in for-next, the alignment
could be made before upstreaming occurs.

8cc31dc941 Merge series "regulator: mt6397: Implement of_map_mode regulator_desc function" from Anand K Mistry <amistry@google.com>:
This patchset adds support for being able to change regulator modes for
the mt6397 regulator. This is needed to allow the voltage scaling
support in the MT8173 SoC to be used on the elm (Acer Chromebook R13)
and hana (several Lenovo Chromebooks) devices.

Without a of_map_mode implementation, the regulator-allowed-modes
devicetree field is skipped, and attempting to change the regulator mode
results in an error:
[    1.439165] vpca15: mode operation not allowed

Changes in v2:
- Introduce constants in dt-bindings
- Improve conditional readability

Anand K Mistry (4):
  regulator: mt6397: Move buck modes into header file
  dt-bindings: regulator: mt6397: Document valid modes
  regulator: mt6397: Implement of_map_mode
  arm64: dts: mediatek: Update allowed mt6397 regulator modes for elm

7d34aec52d regulator: da9062: refactor buck modes into header
This patch refactors buck modes into a header file so that device trees
can make use of these mode constants.

The new header filename uses da9063 because DA9063 was the earlier chip
and its driver code will want updating at some point in a similar manner.

0db021f7a2 regulator: dt-bindings: add QCOM RPMh regulator bindings
Introduce bindings for RPMh regulator devices found on some
Qualcomm Technlogies, Inc. SoCs.  These devices allow a given
processor within the SoC to make PMIC regulator requests which
are aggregated within the RPMh hardware block along with requests
from other processors in the SoC to determine the final PMIC
regulator hardware state.
