Merge series "Add frequency / voltage scaling support for IPQ6018 SoC" from Kathiravan T <kathirav@codeaurora.org>:

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

Kathiravan T (6):
  dt-bindings: soc: qcom: Add IPQ6018 compatible
  soc: qcom: smd-rpm: Add IPQ6018 compatible
  dt-bindings: regulator: add MP5496 regulator compatible
  regulator: qcom_smd: Add MP5496 regulators
  dt-bindings: soc: qcom: convert the SMD-RPM document to YAML schema
  dt-bindings: regulator: convert QCOM SMD-RPM regulator document to
    YAML schema
