-Qualcomm PMIC Multi-Purpose Pin (MPP) block
-
-This binding describes the MPP block(s) found in the 8xxx series
-of PMIC's from Qualcomm.
-
-- compatible:
-	Usage: required
-	Value type: <string>
-	Definition: Should contain one of:
-		    "qcom,pm8018-mpp",
-		    "qcom,pm8019-mpp",

-
-		    And must contain either "qcom,spmi-mpp" or "qcom,ssbi-mpp"
-		    if the device is on an spmi bus or an ssbi bus respectively.
-
-- reg:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: Register base of the MPP block and length.
-
-- interrupts:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: Must contain an array of encoded interrupt specifiers for
-		    each available MPP
-
-- gpio-controller:
-	Usage: required
-	Value type: <none>
-	Definition: Mark the device node as a GPIO controller
-
-- #gpio-cells:
-	Usage: required
-	Value type: <u32>
-	Definition: Must be 2;
-		    the first cell will be used to define MPP number and the
-		    second denotes the flags for this MPP
-
-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:
-
-- pins:
-	Usage: required
-	Value type: <string-array>
-	Definition: List of MPP pins affected by the properties specified in
-		    this subnode.  Valid pins are:
-		    mpp1-mpp4 for pm8841
-		    mpp1-mpp4 for pm8916
-		    mpp1-mpp8 for pm8941
-		    mpp1-mpp4 for pm8950
-		    mpp1-mpp4 for pmi8950
-		    mpp1-mpp4 for pma8084
-
-- function:
-	Usage: required
-	Value type: <string>
-	Definition: Specify the alternative function to be configured for the
-		    specified pins.  Valid values are:
-		    "digital",
-		    "analog",

-
-- bias-disable:
-	Usage: optional
-	Value type: <none>
-	Definition: The specified pins should be configured as no pull.
-
-- bias-pull-up:

-		    only, i.e. when operating in qcom,analog-mode and input and
-		    outputs are enabled. The hardware ignores the configuration
-		    when operating in other modes.

-		    high.
-

-		    defined in <dt-binding/pinctrl/qcom,pmic-mpp.h>
-		    PMIC_MPP_AOUT_LVL_*
-
-- qcom,dtest:
-	Usage: optional
-	Value type: <u32>

-	Definition: Selects the source for analog input. Valid values are
-		    defined in <dt-bindings/pinctrl/qcom,pmic-mpp.h>

-Example:
