    Subject[PATCH V2 3/3] dt-bindings: pinctrl: qcom-pmic-gpio: Convert qcom pmic gpio bindings to YAML
    Date
    Convert Qualcomm PMIC GPIO bindings from .txt to .yaml format.

    Signed-off-by: satya priya <skakit@codeaurora.org>
    ---
    Changes in V3:
    - As per Rob's comments fixed bot erros.
    - Moved this patch to end of the series so that other patches are not
    blocked on this.

    -
    -Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
    -a general description of GPIO and interrupt bindings.
    -
    -Please refer to pinctrl-bindings.txt in this directory for details of the
    -common pinctrl bindings used by client devices, including the meaning of the
    -phrase "pin configuration node".
    -
    -The pin configuration nodes act as a container for an arbitrary number of
    -subnodes. Each of these subnodes represents some desired configuration for a
    -pin or a list of pins. This configuration can include the
    -mux function to select on those pin(s), and various pin configuration
    -parameters, as listed below.
    -
    -
    -SUBNODES:
    -
    -The name of each subnode is not important; all subnodes should be enumerated
    -and processed purely based on their content.
    -
    -Each subnode only affects those parameters that are explicitly listed. In
    -other words, a subnode that lists a mux function but no pin configuration
    -parameters implies no information about any pin configuration parameters.
    -Similarly, a pin subnode that describes a pullup parameter implies no
    -information about e.g. the mux function.
    -
    -The following generic properties as defined in pinctrl-bindings.txt are valid
    -to specify in a pin configuration subnode:
    -
