Subject: [PATCH] arm64: dts: ls1043a: update USB nodes status to match board

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