| 4 | Subject: [PATCH] arm64: dts: ls1043a: update USB nodes status to match board |
| 5 | config |

| 10 | ls1043a-rdb and ls1043a-qds board’s default HW config (such as |
| 11 | pin mux selection) would not enable some USB controllers’ |
| 12 | data path, which causing over-current detected on those |
| 13 | controllers. This will hit the case of ‘xhci driver prevent bus suspend |
| 14 | if a root hub port detected over-current condition’, causing system |
| 15 | failed to be suspended. So disable them in device tree to resolve this |
| 16 | issue. |
