Next in thread: Javier Martinez Canillas: "[PATCH v3 2/5] regulator: core: Add regulator mode and initial mode properties"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
the max77802 driver supports changing the regulator operating
mode during runtime and when the system enters into sleep mode.

To lower power during suspend, configure the regulators state
using the same configuration found in the ChromeOS 3.8 kernel.

Changes since v2:
- Use the standard suspend state binding as suggested by Mark Brown.
