What's the expected plan for merging this - should I be applying the DRM patch?

I'd pick the least two patches into msm-next after -rc1.

[1/4] dt-bindings: regulator: Describe Qualcomm REFGEN regulator commit: d16db38c2a66060ee25c6b86ee7b6d66d40fc8e0 [2/4] regulator: Introduce Qualcomm REFGEN regulator driver commit: 7cbfbe23796086fdb72b681e2c182b02acd36a04 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
Recent Qualcomm SoCs have a REFGEN (reference voltage generator) regulator responsible for providing a reference voltage to some on-SoC IPs (like DSI or PHYs). It can be turned off when unused to save power. This series introduces the driver for it and lets the DSI driver consume it.
