Hi,
- convert DT binding to YAML
- add DT property to disable charger detection
(Errata i2075 for AM65 SR1.0)
Changelog:
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.
cheers,
-roger

AM654x PG1.0 has a silicon bug that D+ is pulled high after POR, which
could cause enumeration failure with some USB hubs. Disabling the
USB2_PHY Charger Detect function will put D+ into the normal state.
Using property "ti,disable-charger-det" in the DT usb2-phy node to
enable this workaround for AM654x PG1.0.
This addresses Silicon Errata:
i2075 - "USB2PHY: USB2PHY Charger Detect is Enabled by Default Without VBUS
Presence"
