Subject: [PATCH v5] dt-binding: phy: convert ti,omap-usb2 to YAML
Move ti,omap-usb2 to its own YAML schema.
Signed-off-by: Roger Quadros <rogerq@...com>
Reviewed-by: Rob Herring <robh@...nel.org>

Changelog:
v5
- Added "ti,am437x-usb2" compatible.
v4
- fix example to fix dt_binding_check warnings
- '#phy-cells' -> "#phy-cells"
- Add 'oneOf' to compatible logic to allow just "ti,omap-usb2" as valid
v3
- Removed quotes from compatibles
- changed property to "ti,disable-charger-det"
v2
- Address Rob's comments on YAML schema.

-OMAP USB2 PHY
-
-Required properties:
- - compatible: Should be "ti,omap-usb2"
- Should be "ti,dra7x-usb2" for the 1st instance of USB2 PHY on
- DRA7x
- Should be "ti,dra7x-usb2-phy2" for the 2nd instance of USB2 PHY
- in DRA7x
- Should be "ti,am654-usb2" for the USB2 PHYs on AM654.
- - reg : Address and length of the register set for the device.
- - #phy-cells: determine the number of cells that should be given in the
- phandle while referencing this phy.
- - clocks: a list of phandles and clock-specifier pairs, one for each entry in
- clock-names.
- - clock-names: should include:
- * "wkupclk" - wakeup clock.
- * "refclk" - reference clock (optional).
-
-Deprecated properties:
- - ctrl-module : phandle of the control module used by PHY driver to power on
- the PHY.
-
-Recommended properies:
-- syscon-phy-power : phandle/offset pair. Phandle to the system control
- module and the register offset to power on/off the PHY.
-
-This is usually a subnode of ocp2scp to which it is connected.
