mfd: Add power off functionality to TWL
TWL family of PMICs, used in master mode, have a power off
functionality. The resulting power off sequence shuts down all the SoC
supplies, LDOs, etc. The sequence is described in the datasheets
chapter "Power-Off Sequence".
Note, that board must be wired correctly for the power off to work as
expected.
