scsi: ufs: host: mediatek: Require CONFIG_PM

2026-02-04T03:28:44+00:00

The added print statement from a recent fix causes the driver to fail building when CONFIG_PM is disabled: drivers/ufs/host/ufs-mediatek.c: In function 'ufs_mtk_resume': drivers/ufs/host/ufs-mediatek.c:1890:40: error: 'struct dev_pm_info' has no member named 'request' 1890 | hba->dev->power.request, It seems unlikely that the driver can work at all without CONFIG_PM, so just add a dependency and remove the existing ifdef checks, rather than adding another ifdef.

scsi: ufs: mediatek: Fix page faults in ufs_mtk_clk_scale() trace event

2026-02-04T03:25:49+00:00

The ufs_mtk_clk_scale() trace event currently stores the address of the name string directly via __field(const char *, name). This pointer may become invalid after the module is unloaded, causing page faults when the trace buffer is subsequently accessed. This can occur because the MediaTek UFS driver can be configured as a loadable module (tristate in Kconfig), meaning the name string passed to the trace event may reside in module memory that becomes invalid after module unload. Fix this by using __string() and __assign_str() to copy the string contents into the ring buffer instead of storing the pointer. This ensures the trace data remains valid regardless of module state. This change increases the memory usage for each ftrace entry by a few bytes (clock names are typically 7-15 characters like "ufs_sel" or "ufs_sel_max_src") compared to storing an 8-byte pointer. Note that this change does not affect anything unless all of the following conditions are met: - CONFIG_SCSI_UFS_MEDIATEK is enabled - ftrace tracing is enabled - The ufs_mtk_clk_scale event is enabled in ftrace Signed-off-by: Keita Morisaki Reviewed-by: Peter Wang Link: https://patch.msgid.link/20260202024526.122515-1-keita.morisaki@tier4.jp Signed-off-by: Martin K.

scsi: ufs: amd-versal2: Fix PHY initialization in HCE enable notify

2026-01-24T03:43:44+00:00

Move the PHY initialization from PRE_CHANGE to POST_CHANGE in the ufs_versal2_hce_enable_notify() callback. This ensures that the PHY is initialized after the host controller enable sequence is complete, rather than before it starts. The PHY initialization requires the UFS host controller to be in a stable enabled state to properly configure the MPHY registers. Moving this to POST_CHANGE aligns with the expected initialization order and prevents potential timing issues during controller startup.

Merge patch series "ufs: ufs-qcom: Add support firmware managed platforms"

2026-01-24T03:07:51+00:00

Ram Kumar Dwivedi says: On Qualcomm automotive SoC SA8255P, platform resource like clocks, interconnect, resets, regulators and PHY are configured remotely by firmware. Logical power domain is used to abstract these resources in firmware and SCMI power protocol is used to request resource operations by using runtime PM framework APIs such as pm_runtime_get/put_sync to invoke power_on/_off calls from kernel respectively.

scsi: ufs: ufs-qcom: Add support for firmware-managed resource abstraction

2026-01-24T03:04:33+00:00

Add a compatible string for SA8255p platforms where resources such as PHY, clocks, regulators, and resets are managed by firmware through an SCMI server. Use the SCMI power protocol to abstract these resources and invoke power operations via runtime PM APIs (pm_runtime_get/put_sync). Introduce vendor operations (vops) for SA8255p targets to enable SCMI- based resource control. In this model, capabilities like clock scaling and gating are not yet supported; these will be added incrementally.

scsi: ufs: qcom: Fix confusing cleanup.h syntax

2025-12-09T03:11:00+00:00

Initializing automatic __free variables to NULL without need (e.g. branches with different allocations), followed by actual allocation is in contrary to explicit coding rules guiding cleanup.h: "Given that the "__free(...) = NULL" pattern for variables defined at the top of the function poses this potential interdependency problem the recommendation is to always define and assign variables in one statement and not group variable definitions at the top of the function when __free() is used." Code does not have a bug, but is less readable and uses discouraged coding practice, so fix that by moving declaration to the place of assignment.
