[PATCH V3 0/4] Add frequency / voltage scaling support for IPQ6018 SoC

[PATCH V3 0/4] Add frequency / voltage scaling support for IPQ6018 SoC

[Kathiravan T]

IPQ6018 SoC uses the PMIC MP5496. SMPA2 and LDOA2 regulator of MP5496
controls the APSS and SDCC voltage scaling respectively. Add support
for the same.

changes since V2:
	- Rebased on top of linux-next 20200717 tag
	- Addressed Rob's comment to drop the 'syscon' node in qcom,smd-rpm.yaml
	- Picked up the Reviewed-by tag for qcom,smd-rpm-regulator.yaml
	- Regulator patches part of V2 was picked up by Mark and it's available in linux-next tree

changes since V1:
	- Moved YAML conversion to the last as per Mark's comments

-QCOM SMD RPM REGULATOR

-The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
-Because SMD is used as the communication transport mechanism, the RPM resides as
-a subnode of the SMD.  As such, the SMD-RPM regulator requires that the SMD and
-RPM nodes be present.

-Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.txt for

+title: QCOM SMD RPM REGULATOR
+
+description:
+  The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
+  Because SMD is used as the communication transport mechanism, the RPM
+  resides as a subnode of the SMD.  As such, the SMD-RPM regulator requires
+  that the SMD and RPM nodes be present.
+
+  Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.txt for
+  information pertaining to the SMD node.
+
+  Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd-rpm.yaml
+  for information regarding the RPM node.
+
+  The regulator node houses sub-nodes for each regulator within the device.
+  Each sub-node is identified using the node's name, with valid values listed
+  for each of the pmics below.

[1/1] regulator: convert QCOM SMD-RPM regulator document to YAML schema
      commit: 175a1d84154d4077da437b873319bd094b266ab8

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
