The UFS interface is designed to be + protocol agnostic, however SCSI has been selected as a baseline + protocol for versions 1.0 and 1.1 of UFS protocol layer. + UFS supports subset of SCSI commands defined by SPC-4 and SBC-3. + * UCS: It handles SCSI commands supported by UFS specification. + * Task manager: It handles task management functions defined by the + UFS which are meant for command queue control. + * Device manager: It handles device level operations and device + configuration operations. Device level operations mainly involve + device power management operations and commands to Interconnect + layers.

UFSHCD Overview +------------------ + +The UFS host controller driver is based on Linux SCSI Framework. +UFSHCD is a low level device driver which acts as an interface between +SCSI Midlayer and PCIe based UFS host controllers. + +The current UFSHCD implementation supports following functionality, + +3.1 UFS controller initialization + + The initialization module brings UFS host controller to active state + and prepares the controller to transfer commands/response between + UFSHCD and UFS device. + +3.2 UTP Transfer requests + + Transfer request handling module of UFSHCD receives SCSI commands + from SCSI Midlayer, forms UPIUs and issues the UPIUs to UFS Host + controller.
