Given that the RTC has been a standard feature since UFS Spec 2.0, and qTimestamp was introduced
in UFS Spec 4.0, the majority of UFS devices currently on the market rely on RTC. Therefore, it
is advisable to continue supporting RTC in the Linux kernel. This ensures compatibility with the
prevailing UFS device implementations and facilitates seamless integration with existing hardware.
By maintaining support for RTC, we ensure broad compatibility and avoid potential issues arising
from deviations in device specifications across different UFS versions.
