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.

MediaTek musb DRD/OTG controller
|
|
-------------------------------------------
|
|
|
|
Required properties:
|
|
- compatible : should be one of:
|
|
"mediatek,mt2701-musb"
|
|
...
|
|
followed by "mediatek,mtk-musb"
|
|
- reg : specifies physical base address and size of
|
|
the registers
|
|
- interrupts : interrupt used by musb controller
|
|
- interrupt-names : must be "mc"
|
|
- phys : PHY specifier for the OTG phy
|
|
- dr_mode : should be one of "host", "peripheral" or "otg",
|
|
refer to usb/generic.txt
|
|
- clocks : a list of phandle + clock-specifier pairs, one for
|
|
each entry in clock-names
|
|
- clock-names : must contain "main", "mcu", "univpll"
|
|
for clocks of controller
|
|
|
|
Optional properties:
|
|
- power-domains : a phandle to USB power domain node to control USB's
|
|
MTCMOS
|
|
|
|
Required child nodes:
|
|
usb connector node as defined in bindings/connector/usb-connector.yaml
|
|
Optional properties:
|
|
- id-gpios : input GPIO for USB ID pin.
|
|
- vbus-gpios : input GPIO for USB VBUS pin.
|
|
- vbus-supply : reference to the VBUS regulator, needed when supports
|
|
dual-role mode
|
|
- usb-role-switch : use USB Role Switch to support dual-role switch, see
|
|
usb/generic.txt.
