   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.
