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

2025-01-17T12:40:45Z

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: ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: ufshcd_host_reset_and_restore: Host init failed -5 ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: ufshcd_host_reset_and_restore: Host init failed -5 ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: ufshcd_host_reset_and_restore: Host init failed -5 ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: ufshcd_host_reset_and_restore: Host init failed -5 ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: Enabling the controller failed ufshcd-qcom 1d84000.ufshc: ufshcd_host_reset_and_restore: Host init failed -5 ufs_device_wlun 0:0:0:49488: ufshcd_wl_resume failed: -5 ufs_device_wlun 0:0:0:49488: PM: dpm_run_callback(): scsi_bus_resume returns -5 ufs_device_wlun 0:0:0:49488: PM: failed to resume async: error -5 Cc: stable@vger.kernel.org # 6.3 Fixes: baf5ddac90dc ("scsi: ufs: ufs-qcom: Add support for reinitializing the UFS device") Reported-by: Ram Kumar Dwivedi Tested-by: Amit Pundir # on SM8550-HDK Reviewed-by: Bart Van Assche Tested-by: Neil Armstrong # on SM8550-QRD Signed-off-by: Manivannan Sadhasivam Link: https://lore.kernel.org/r/20241219-ufs-qcom-suspend-fix-v3-1-63c4b95a70b9@linaro.org Signed-off-by: Martin K.

scsi: ufs: core: Add missing post notify for power mode change

2024-12-14T19:03:25Z

commit 7f45ed5f0cd5ccbbec79adc6c48a67d6a85fba56 upstream. When the power mode change is successful but the power mode hasn't actually changed, the post notification was missed. Similar to the 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 pwr_change_notify callback.

fault-inject: improve build for CONFIG_FAULT_INJECTION=n

The fault-inject.h users across the kernel need to add a lot of #ifdef CONFIG_FAULT_INJECTION to cater for shortcomings in the header. Make fault-inject.h self-contained for CONFIG_FAULT_INJECTION=n, and add stubs for DECLARE_FAULT_ATTR(), setup_fault_attr(), should_fail_ex(), and should_fail() to allow removal of conditional compilation.

scsi: ufs: core: Add a quirk for handling broken LSDBS field in controller capabilities register

2024-08-17T01:09:17Z

'Legacy Queue & Single Doorbell Support (LSDBS)' field in the controller capabilities register is supposed to report whether the legacy single doorbell mode is supported in the controller or not. But some controllers report '1' in this field which corresponds to 'LSDB not supported', but they indeed support LSDB. So let's add a quirk to handle those controllers. If the quirk is enabled by the controller driver, then LSDBS register field will be ignored and legacy single doorbell mode is assumed to be enabled always.

scsi: ufs: core: Check LSDBS cap when !mcq

2024-07-16T02:51:06Z

If the user sets use_mcq_mode to 0, the host will try to activate the LSDB mode unconditionally even when the LSDBS of device HCI cap is 1. This makes commands time out and causes device probing to fail. To prevent that problem, check the LSDBS cap when MCQ is not supported.
