Subject: [PATCH v3 1/2] bindings: pm8941-misc: Convert to YAML and add support for VBUS detection

From: Anirudh Ghayal <aghayal@...eaurora.org>

Convert bindings to YAML. Also add compatible string that adds support
for reporting the VBUS status that can be detected via a dedicated PMIC
pin.

-Qualcomm's PM8941 USB ID Extcon device
-
-Some Qualcomm PMICs have a "misc" module that can be used to detect when
-the USB ID pin has been pulled low or high.

-PROPERTIES

-- compatible:
-    Usage: required
-    Value type: <string>
-    Definition: Should contain "qcom,pm8941-misc";
-
-- reg:
-    Usage: required
-    Value type: <u32>
-    Definition: Should contain the offset to the misc address space
-
-- interrupts:
-    Usage: required
-    Value type: <prop-encoded-array>
-    Definition: Should contain the usb id interrupt
-
-- interrupt-names:
-    Usage: required
-    Value type: <stringlist>
-    Definition: Should contain the string "usb_id" for the usb id interrupt
