Thank you for your reviews. I will incorporate the suggested changes into the patch, addressing all comments except for the RTC mode switch. The proposal is to perform the RTC mode switch during UFS provisioning, not at runtime in the UFS online phase. This approach ensures that the UFS configuration is populated based on the RTC configuration established during provisioning. It is advisable not to change the RTC mode after provisioning is complete. Additionally, the usage of tv_sec, which returns time elapsed since boot, suggests that there is no issue with utilizing the RTC in this context. Kind regards, Bean
