| Subject: [PATCH] arm64: dts: meson: odroid-c2: Disable usb_otg bus to avoid |
| power failed warning |
| |
| commit 72c9b5f6f75fbc6c47e0a2d02bc3838a2a47c90a upstream. |
| |
| usb_otg bus needs to get initialize from the u-boot to be configured |
| to used as power source to SBC or usb otg port will get configured |
| as host device. Right now this support is missing in the u-boot and |
| phy driver so to avoid power failed warning, we would disable this |
| feature until proper fix is found. |
