Subject: [PATCH] dt-bindings: Convert usb-connector to YAML format.
Date:   Wed,  4 Mar 2020 09:49:35 -0800
Message-Id: <20200304174942.124070-1-pmalani@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Convert the usb-connector.txt bindings file to YAML format. This allows
it to be used in dt_bindings_check verification. This patch was
born out of a patch series for the addition of a Type C connector
class port driver[1].

An attempt has been made to maintain the same documentation text and
example structure as was in the .txt file, but wherever needed
modifications have been made to satisfy dt_bindings_check.

Also, update all references to usb-connector.txt to now use
usb-connector.yaml.

-USB Connector
-=============
-
-A USB connector node represents a physical USB connector. It should be
-a child of a USB interface controller.
-
-Required properties:
-- compatible: describes type of the connector, must be one of:
-    "usb-a-connector",
-    "usb-b-connector",
-    "usb-c-connector".
-
-Optional properties:
-- label: symbolic name for the connector,
-- type: size of the connector, should be specified in case of USB-A, USB-B
-  non-fullsize connectors: "mini", "micro".
-- self-powered: Set this property if the usb device that has its own power
-  source.
-
-Optional properties for usb-b-connector:
-- id-gpios: an input gpio for USB ID pin.
-- vbus-gpios: an input gpio for USB VBUS pin, used to detect presence of
-  VBUS 5V.
-  see gpio/gpio.txt.
-- vbus-supply: a phandle to the regulator for USB VBUS if needed when host
-  mode or dual role mode is supported.
-  Particularly, if use an output GPIO to control a VBUS regulator, should
-  model it as a regulator.
-  see regulator/fixed-regulator.yaml
-- pinctrl-names : a pinctrl state named "default" is optional
-- pinctrl-0 : pin control group
-  see pinctrl/pinctrl-bindings.txt
-
-Optional properties for usb-c-connector:
-- power-role: should be one of "source", "sink" or "dual"(DRP) if typec
-  connector has power support.
-- try-power-role: preferred power role if "dual"(DRP) can support Try.SNK
-  or Try.SRC, should be "sink" for Try.SNK or "source" for Try.SRC.
-- data-role: should be one of "host", "device", "dual"(DRD) if typec
-  connector supports USB data.
-
-Required properties for usb-c-connector with power delivery support:
-- source-pdos: An array of u32 with each entry providing supported power
-  source data object(PDO), the detailed bit definitions of PDO can be found
-  in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.2
-  Source_Capabilities Message, the order of each entry(PDO) should follow
-  the PD spec chapter 6.4.1. Required for power source and power dual role.
-  User can specify the source PDO array via PDO_FIXED/BATT/VAR/PPS_APDO()
-  defined in dt-bindings/usb/pd.h.
-- sink-pdos: An array of u32 with each entry providing supported power
-  sink data object(PDO), the detailed bit definitions of PDO can be found
-  in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.3
-  Sink Capabilities Message, the order of each entry(PDO) should follow
-  the PD spec chapter 6.4.1. Required for power sink and power dual role.
-  User can specify the sink PDO array via PDO_FIXED/BATT/VAR/PPS_APDO() defined
-  in dt-bindings/usb/pd.h.
-- op-sink-microwatt: Sink required operating power in microwatt, if source
-  can't offer the power, Capability Mismatch is set. Required for power
-  sink and power dual role.
-
-Required nodes:
-- any data bus to the connector should be modeled using the OF graph bindings
-  specified in bindings/graph.txt, unless the bus is between parent node and
-  the connector. Since single connector can have multiple data buses every bus
-  has assigned OF graph port number as follows:
-    0: High Speed (HS), present in all connectors,
-    1: Super Speed (SS), present in SS capable connectors,
-    2: Sideband use (SBU), present in USB-C.
-
-Examples
---------

-};
-
-2. USB-C connector attached to CC controller (s2mm005), HS lines routed
-to companion PMIC (max77865), SS lines to USB3 PHY and SBU to DisplayPort.
-DisplayPort video lines are routed to the connector via SS mux in USB3 PHY.
