[...] Yes. This is the same race as in your review of patch 2, and the fix is in the driver. In v3 the mux callback no longer resumes the glue. >From the start of a runtime or system suspend until the core has resumed, it only records the state. dwc3_qcom_resume() applies it before the core resumes. v3 also compares with the clock selected in QSCRATCH instead of a cached value, so a selection lost with QSCRATCH in system suspend is restored on resume. As Krzysztof asked, the DTS patch is now sent on its own: https://lore.kernel.org/all/20261112113921.1143-1-26rote@gmail.com/ Thanks, Joonhoe Kim
