[PATCH v3 0/3] arm64: dts: qcom: x1e80100: fix USB OTG regressions

[Johan Hovold]

A recent change enabling OTG mode on the Lenovo ThinkPad T14s USB-C
ports can break SuperSpeed device hotplugging.

Abel noticed that the corresponding commit for the CRD also triggers a
hard reset during resume from suspend.

Dmitry had already reported that enabling role switching can break UCSI.

With retimer (and orientation detection) support not even merged yet,
let's revert at least until we have stable host mode in mainline.

Note that Stephan has also identified other problems with the offending
commits here:

Changes in v3
 - revert also the dtsi change that enable role-switching since it
   breaks UCSI (and DisplayPort alt mode) when the controllers are in
   host mode

Changes in v2
 - revert also the corresponding patch for the CRD which breaks suspend
