    Subject[PATCH 13/13] power: reset: ltc2952: document optional trigger behavior
    Date
    Document the fact that the trigger signal is now optional, and describe
    the behavior when this is used.

    While at it, fix a typo, and paraphrase a sentence to be less platform
    specific.

    Binding for the LTC2952 PowerPath controller

    This chip is used to externally trigger a system shut down. Once the trigger has
    -been sent, the chips' watchdog has to be reset to gracefully shut down.
    -If the Linux systems decides to shut down it powers off the platform via the
    -kill signal.
    +been sent, the chip's watchdog has to be reset to gracefully shut down.
    +A full powerdown can be triggered via the kill signal.

    Required properties:

    - compatible: Must contain: "lltc,ltc2952"
    -- trigger-gpios: phandle + gpio-specifier for the GPIO connected to the
    - chip's trigger line
    - watchdog-gpios: phandle + gpio-specifier for the GPIO connected to the
    chip's watchdog line
    - kill-gpios: phandle + gpio-specifier for the GPIO connected to the
    chip's kill line

    +Optional properties:
    +- trigger-gpios: phandle + gpio-specifier for the GPIO connected to the
    + chip's trigger line. If this property is not set, the
    + trigger function is ignored and the chip is kept alive
    + until an explicit kill signal is received
    +
    Example:
