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

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 ^ permalink raw reply [flat|nested] 11+ messages in thread
