Merge branch 's3-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/amit/virtio-console
Pull virtio S3 support patches from Amit Shah:
"Turns out S3 is not different from S4 for virtio devices: the device
is assumed to be reset, so the host and guest state are to be assumed
to be out of sync upon resume. We handle the S4 case with exactly the
same scenario, so just point the suspend/resume routines to the
freeze/restore ones.
Once that is done, we also use the PM API's macro to initialise the
sleep functions.
A couple of cleanups are included: there's no need for special thaw
processing in the balloon driver, so that's addressed in patches 1 and
2.
Testing: both S3 and S4 support have been tested using these patches
using a similar method used earlier during S4 patch development: a
guest is started with virtio-blk as the only disk, a virtio network
card, a virtio-serial port and a virtio balloon device. Ping from
guest to host, dd /dev/zero to a file on the disk, and IO from the
host on the virtio-serial port, all at once, while exercising S4 and
S3 (separately) were tested. They all continue to work fine after
resume. virtio balloon values too were tested by inflating and
deflating the balloon."
Pulling from Amit, since Rusty is off getting married (and presumably
shaving people).

+
+1. Overview
+-----------
+
+Universal Flash Storage(UFS) is a storage specification for flash devices.
+It is aimed to provide a universal storage interface for both
+embedded and removable flash memory based storage in mobile
+devices such as smart phones and tablet computers. The specification
+is defined by JEDEC Solid State Technology Association. UFS is based
+on MIPI M-PHY physical layer standard. UFS uses MIPI M-PHY as the
+physical layer and MIPI Unipro as the link layer.
+
+The main goals of UFS is to provide,
+ * Optimized performance:
+ For UFS version 1.0 and 1.1 the target performance is as follows,
+ Support for Gear1 is mandatory (rate A: 1248Mbps, rate B: 1457.6Mbps)
+ Support for Gear2 is optional (rate A: 2496Mbps, rate B: 2915.2Mbps)
+ Future version of the standard,
+ Gear3 (rate A: 4992Mbps, rate B: 5830.4Mbps)
+ * Low power consumption
+ * High random IOPs and low latency
+
+
+2. UFS Architecture Overview
+----------------------------
+
+UFS has a layered communication architecture which is based on SCSI
+SAM-5 architectural model.
+
+UFS communication architecture consists of following layers,
+
+2.1 Application Layer
+
+ The Application layer is composed of UFS command set layer(UCS),
+ Task Manager and Device manager. 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. Device level configurations involve handling of query
+ requests which are used to modify and retrieve configuration
+ information of the device.
+
+2.2 UFS Transport Protocol(UTP) layer
+
+ UTP layer provides services for
+ the higher layers through Service Access Points. UTP defines 3
+ service access points for higher layers.
+ * UDM_SAP: Device manager service access point is exposed to device
+ manager for device level operations. These device level operations
+ are done through query requests.
+ * UTP_CMD_SAP: Command service access point is exposed to UFS command
+ set layer(UCS) to transport commands.
+ * UTP_TM_SAP: Task management service access point is exposed to task
+ manager to transport task management functions.
+ UTP transports messages through UFS protocol information unit(UPIU).
+
+2.3 UFS Interconnect(UIC) Layer
+
+ UIC is the lowest layer of UFS layered architecture. It handles
+ connection between UFS host and UFS device. UIC consists of
+ MIPI UniPro and MIPI M-PHY. UIC provides 2 service access points
+ to upper layer,
+ * UIC_SAP: To transport UPIU between UFS host and UFS device.
+ * UIO_SAP: To issue commands to Unipro layers.
+
+
+3. 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. Also, the module decodes, responses received from UFS
+ host controller in the form of UPIUs and intimates the SCSI Midlayer
+ of the status of the command.
+
+3.3 UFS error handling
+
+ Error handling module handles Host controller fatal errors,
+ Device fatal errors and UIC interconnect layer related errors.
+
+3.4 SCSI Error handling
+
+ This is done through UFSHCD SCSI error handling routines registered
+ with SCSI Midlayer. Examples of some of the error handling commands
+ issues by SCSI Midlayer are Abort task, Lun reset and host reset.
+ UFSHCD Routines to perform these tasks are registered with
+ SCSI Midlayer through .eh_abort_handler, .eh_device_reset_handler and
+ .eh_host_reset_handler.
+
+In this version of UFSHCD Query requests and power management
+functionality are not implemented.
