The RTC part works: rtc-qcom-gio reads the correct UTC time. But UCSI breaks when pmic_glink_gio is bound, although the commit message says ucsi stays on the legacy interface: - pmic_glink_gio loaded at boot: ucsi_glink fails with "error -ETIMEDOUT: PPM init failed", no typec ports. - pmic_glink_gio blacklisted (patched pmic_glink still loaded): typec ports and partners come up, plug/unplug is seen. - Same boot, then modprobe pmic_glink_gio: the RTC works and the ports stay, but UCSI no longer sees any plug or unplug (old partners stay). USB data and charging still work. Happy to test a fix. Jeff
