    Subject[PATCH 07/12] mfd: dt-bindings: samsung,s2mps11: convert to dtschema
    Date
    Convert the MFD part of Samsung S2MPS11/S2MPS13/S2MPS14/S2MPS15/S2MPU02
    family of PMICs to DT schema format. Previously the bindings were
    mostly in mfd/samsung,sec-core.txt.

    The conversion copies parts of description from existing bindings
    therefore the license is not changed from GPLv2.

    +description: |
    + This is a part of device tree bindings for S2M and S5M family of Power
    + Management IC (PMIC).
    +
    + The Samsung S2MPS11/13/14/15 and S2MPU02 is a family of Power Management IC
    + which include voltage and current regulators, RTC, clock outputs and other
    + sub-blocks.

    + low, the rising ACOKB will trigger power off.
