scsi: ufs: core: Add UFS RTC support

scsi: ufs: core: Add UFS RTC support

[ Upstream commit 6bf999e0eb41850d5c857102535d5c53b2ede224 ]

Add Real Time Clock (RTC) support for UFS device. This enhancement is
crucial for the internal maintenance operations of the UFS device. The
patch enables the device to handle both absolute and relative time
information. Furthermore, it includes periodic task to update the RTC in
accordance with the UFS Spec, ensuring the accuracy of RTC information for
the device's internal processes.

RTC and qTimestamp serve distinct purposes. The RTC provides a coarse level
of granularity with, at best, approximate single-second resolution. This
makes the RTC well-suited for the device to determine the approximate age
of programmed blocks after being updated by the host. On the other hand,
qTimestamp offers nanosecond granularity and is specifically designed for
synchronizing Device Error Log entries with corresponding host-side logs.

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.

scsi: ufs: qcom: Power off the PHY if it was already powered on in ufs_qcom_power_up_sequence()

commit 7bac65687510038390a0a54cbe14fba08d037e46 upstream.

PHY might already be powered on during ufs_qcom_power_up_sequence() in a
couple of cases:

1. During UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH quirk

2. Resuming from spm_lvl = 5 suspend

In those cases, it is necessary to call phy_power_off() and phy_exit() in
ufs_qcom_power_up_sequence() function to power off the PHY before calling
phy_init() and phy_power_on().

Case (1) is doing it via ufs_qcom_reinit_notify() callback, but case (2) is
not handled. So to satisfy both cases, call phy_power_off() and phy_exit()
if the phy_count is non-zero. And with this change, the reinit_notify()
callback is no longer needed.

This fixes the below UFS resume failure with spm_lvl = 5:

approach with hibernate/clock scale/hce enable, having pre/post
notifications in the same function will make it easier to maintain.

Additionally, supplement the description of power parameters for the

- Simplify the code for creating and parsing UFS Transport Protocol (UTP)
