Subject: Applied "regulator: added support for suspend states" to the regulator tree
Date: Fri, 26 Jan 2018 15:26:12 +0000	[thread overview]
Message-ID: <E1ef5tM-0006fT-89@debutante> (raw)
In-Reply-To: <>

The patch

   regulator: added support for suspend states

has been applied to the regulator tree at 

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.

Subject: [PATCH] regulator: added support for suspend states

Some systems need to set regulators to specific states when they enter
low power modes, especially around CPUs. There are many of these modes
depending on the particular runtime state.

Currently the regulator consumers are not granted permission to change
suspend state of regulator devices, the constraints are configured at
startup.  In order to allow changes in a vlotage range, we need to add
new properties for voltage range and a flag to give permission to
change the suspend voltage and suspend on/off in suspend mode.
