Andrejs Cainikovs 64819aaad2 arm64: dts: ti: k3-am62-main: disable usb lpm ... [ Upstream commit 9c99b337a8 ] AM62 USB works with some devices, while failing to operate with others. [ 560.189822] xhci-hcd xhci-hcd.4.auto: xHCI Host Controller [ 560.195631] xhci-hcd xhci-hcd.4.auto: new USB bus registered, assigned bus number 2 [ 574.388509] xhci-hcd xhci-hcd.4.auto: can't setup: -110 [ 574.393814] xhci-hcd xhci-hcd.4.auto: USB bus 2 deregistered [ 574.399544] xhci-hcd: probe of xhci-hcd.4.auto failed with error -110 This seems to be related to LPM (Link Power Management), and disabling it turns USB into reliable working state. As per AM62 reference manual: > 4.8.2.1 USB2SS Unsupported Features > > The following features are not supported on this family of devices: > ... > - USB 2.0 ECN: Link Power Management (LPM) > ...
