From 2dfd145470894296d70873942ae056340e3fd78d Mon Sep 17 00:00:00 2001 From: Ran Wang Date: Tue, 7 Jul 2020 15:40:31 +0800 Subject: [PATCH] arm64: dts: ls1043a: update USB nodes status to match board config MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
