This is a direct conversion of the existing txt documentation to YAML.
It is in preparation for the addition of pronto-v3 to the docs. This
patch doesn't document any of the existing subnodes/properties that are
not documented in the existing txt file. That is done in a separate
patch.

-This document defines the binding for a component that loads and boots firmware
-on the Qualcomm WCNSS core.
-
-- compatible:
- Usage: required
- Value type: <string>
- Definition: must be one of:
- "qcom,riva-pil",
- "qcom,pronto-v1-pil",
- "qcom,pronto-v2-pil"
-
-- reg:
- Usage: required
- Value type: <prop-encoded-array>

-= SUBNODES
-A required subnode of the WCNSS PIL is used to describe the attached rf module
-and its resource dependencies. It is described by the following properties:
-
-- compatible:
- Usage: required
- Value type: <string>
- Definition: must be one of:
- "qcom,wcn3620",
- "qcom,wcn3660",
- "qcom,wcn3660b",
- "qcom,wcn3680"
-
-- clocks:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: should specify the xo clock and optionally the rf clock
-
-- clock-names:
- Usage: required
- Value type: <stringlist>
- Definition: should be "xo", optionally followed by "rf"
-
-- vddxo-supply:
-- vddrfa-supply:
-- vddpa-supply:
-- vdddig-supply:
- Usage: required
- Value type: <phandle>
- Definition: reference to the regulators to be held on behalf of the
- booting of the WCNSS core
-
-
-The wcnss node can also have an subnode named "smd-edge" that describes the SMD
-edge, channels and devices related to the WCNSS.
-See ../soc/qcom/qcom,smd.yaml for details on how to describe the SMD edge.
-
-= EXAMPLE
-The following example describes the resources needed to boot control the WCNSS,
-with attached WCN3680, as it is commonly found on MSM8974 boards.
