It seems the "phy_index++;" have been placed in wrong place, without it the while circle up will do a infinite loop. Signed-off-by:

There is a error message within devm_ioremap_resource already, so remove the dev_err call to avoid redundant error message. Signed-off-by:

scsi_remove_host() sends SYNCHRONIZE CACHE commands for write cache enabled scsi disk devices. So stopping controller working shouldn't be done before scsi_remove_host(). Signed-off-by:

When removing the UFS driver, disable_irq() is called and the IRQ is not enabled again. Unfortunately, the IRQ is requested with IRQF_SHARED and it can be shared among several devices. So disabling the IRQ in this way is just breaking other devices which are sharing the IRQ. Signed-off-by:

Before commit 2953f850 ("[SCSI] ufs: use devres functions for ufshcd"), UFSHCI register was ioremapped by each glue-driver (ufshcd-pltfrm and ufshcd-pci) during probing and it was iounmapped by core-driver during removing driver. The commit converted ufshcd-pltfrm to use devres functions, but it didn't convert ufshcd-pci. Therefore, the change causes ufshcd-pci driver not to iounmap UFSHCI register region during removing driver. This fixes it by converting ufshcd-pci to use devres functions. Signed-off-by:

Add runtime PM helpers to suspend/resume UFS controller at runtime. Enable runtime PM by default for pci and platform drivers as the initialized hardware can suspend if it is not used after bootup. Signed-off-by:

Background operations in the UFS device can be disabled by the host to reduce the response latency of transfer requests. Add support for enabling/disabling the background operations during runtime suspend/resume of the device. If the device is in critical need of BKOPS it will raise an URGENT_BKOPS exception which should be handled by the host to make sure the device performs as expected. During bootup, the BKOPS is enabled in the device by default. The disable of BKOPS is supported only when the driver supports runtime suspend/resume operations as the runtime PM framework provides a way to determine the device idleness and hence BKOPS can be managed effectively. During runtime resume the BKOPS is disabled to reduce latency and during runtime suspend the BKOPS is enabled to allow device to carry out idle time BKOPS. In some cases where the BKOPS is disabled during runtime resume and due to continuous data transfers the runtime suspend is not triggered, the BKOPS is enabled when the device raises a level-2 exception (outstanding operations - performance impact).

Allow UFS device to complete its initialization and accept SCSI commands by setting fDeviceInit flag. The device may take time for this operation and hence the host should poll until fDeviceInit flag is toggled to zero. This step is mandated by UFS device specification for device initialization completion. Signed-off-by:

As part of device initialization sequence, sending NOP OUT UPIU and waiting for NOP IN UPIU response is mandatory. This confirms that the device UFS Transport (UTP) layer is functional and the host can configure the device with further commands. Add support for sending NOP OUT UPIU to check the device connection path and test whether the UTP layer on the device side is functional during initialization. A tag is acquired from the SCSI tag map space in order to send the device management command. When the tag is acquired by internal command the scsi command is rejected with host busy flag in order to requeue the request. To avoid frequent collisions between internal commands and scsi commands the device management command tag is allocated in the opposite direction w.r.t block layer tag allocation. Signed-off-by:
