Abel noticed that the corresponding commit for the CRD also triggers a hard reset during resume from suspend. 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 and Dmitry have already identified other problems with the offending commits here: https://lore.kernel.org/all/ZxZO6Prrm2ITUZMQ@linaro.org/ https://lore.kernel.org/all/hw2pdof4ajadjsjrb44f2q4cz4yh5qcqz5d3l7gjt2koycqs3k@xx5xvd26uyef Johan Changes in v2 - revert also the corresponding patch for the CRD which breaks suspend Johan Hovold (2): Revert "arm64: dts: qcom: x1e78100-t14s: enable otg on usb-c ports" Revert "arm64: dts: qcom: x1e80100-crd: enable otg on usb ports" .../boot/dts/qcom/x1e78100-lenovo-thinkpad-t14s.dts | 8 ++++++++ arch/arm64/boot/dts/qcom/x1e80100-crd.dts | 12 ++++++++++++ 2 files changed, 20 insertions(+)
