Merge tag 'asoc-fix-v4.10-rc3' into asoc-linus

ASoC: Fixes for v4.10 As well as the usual smattering of driver specific fixes collected since the merge window this has one particularly important fix to the core for handling of aux_devs which was broken during the merge window by some of the componentization refactoring. # gpg: Signature made Wed 11 Jan 2017 17:26:37 GMT # gpg: using RSA key ADE668AA675718B59FE29FEA24D68B725D5487D0 # gpg: issuer "broonie@kernel.org" # gpg: key 0D9EACE2CD7BEEBC: no public key for trusted key - skipped # gpg: key 0D9EACE2CD7BEEBC marked as ultimately trusted # gpg: key CCB0A420AF88CD16: no public key for trusted key - skipped # gpg: key CCB0A420AF88CD16 marked as ultimately trusted # gpg: key 162614E316005C11: no public key for trusted key - skipped # gpg: key 162614E316005C11 marked as ultimately trusted # gpg: key A730C53A5621E907: no public key for trusted key - skipped # gpg: key A730C53A5621E907 marked as ultimately trusted # gpg: key 276568D75C6153AD: no public key for trusted key - skipped # gpg: key 276568D75C6153AD marked as ultimately trusted # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" [ultimate] # gpg: aka "Mark Brown <broonie@debian.org>" [ultimate] # gpg: aka "Mark Brown <broonie@kernel.org>" [ultimate] # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" [ultimate] # gpg: aka "Mark Brown <broonie@linaro.org>" [ultimate] # gpg: aka "Mark Brown <Mark.Brown@linaro.org>" [ultimate]

- * struct cec_msg - CEC message structure.
- * @tx_ts:	Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
- *		driver when the message transmission has finished.
- * @rx_ts:	Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
- *		driver when the message was received.
- * @len:	Length in bytes of the message.
- * @timeout:	The timeout (in ms) that is used to timeout CEC_RECEIVE.
- *		Set to 0 if you want to wait forever. This timeout can also be
- *		used with CEC_TRANSMIT as the timeout for waiting for a reply.
- *		If 0, then it will use a 1 second timeout instead of waiting
- *		forever as is done with CEC_RECEIVE.
- * @sequence:	The framework assigns a sequence number to messages that are
- *		sent. This can be used to track replies to previously sent
- *		messages.
- * @flags:	Set to 0.
- * @msg:	The message payload.
- * @reply:	This field is ignored with CEC_RECEIVE and is only used by
- *		CEC_TRANSMIT. If non-zero, then wait for a reply with this
- *		opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
- *		a possible ABORT reply. If there was an error when sending the
- *		msg or FeatureAbort was returned, then reply is set to 0.
- *		If reply is non-zero upon return, then len/msg are set to
- *		the received message.
- *		If reply is zero upon return and status has the
- *		CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
- *		the received feature abort message.
- *		If reply is zero upon return and status has the
- *		CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
- *		all. If reply is non-zero for CEC_TRANSMIT and the message is a
- *		broadcast, then -EINVAL is returned.
- *		if reply is non-zero, then timeout is set to 1000 (the required
- *		maximum response time).
- * @rx_status:	The message receive status bits. Set by the driver.
- * @tx_status:	The message transmit status bits. Set by the driver.
- * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
- * @tx_nack_cnt: The number of 'Not Acknowledged' events. Set by the driver.
- * @tx_low_drive_cnt: The number of 'Low Drive Detected' events. Set by the
- *		driver.
- * @tx_error_cnt: The number of 'Error' events. Set by the driver.

+ * @signaled: [optional] peek whether the fence is signaled, can be null.
+ * @wait: custom wait implementation, or dma_fence_default_wait.
+ * @release: [optional] called on destruction of fence, can be null
+ * @fill_driver_data: [optional] callback to fill in free-form debug info
+ * Returns amount of bytes filled, or -errno.
+ * @fence_value_str: [optional] fills in the value of the fence as a string
+ * @timeline_value_str: [optional] fills in the current value of the timeline
+ * as a string
+ *
+ * Notes on enable_signaling:
+ * For fence implementations that have the capability for hw->hw
+ * signaling, they can implement this op to enable the necessary
+ * irqs, or insert commands into cmdstream, etc.  This is called
+ * in the first wait() or add_callback() path to let the fence
+ * implementation know that there is another driver waiting on
+ * the signal (ie. hw->sw case).
+ *
+ * This function can be called called from atomic context, but not
+ * from irq context, so normal spinlocks can be used.
+ *
+ * A return value of false indicates the fence already passed,
+ * or some failure occurred that made it impossible to enable
+ * signaling. True indicates successful enabling.
+ *
+ * fence->status may be set in enable_signaling, but only when false is
+ * returned.
+ *
+ * Calling dma_fence_signal before enable_signaling is called allows
+ * for a tiny race window in which enable_signaling is called during,
+ * before, or after dma_fence_signal. To fight this, it is recommended
+ * that before enable_signaling returns true an extra reference is
+ * taken on the fence, to be released when the fence is signaled.
+ * This will mean dma_fence_signal will still be called twice, but
+ * the second time will be a noop since it was already signaled.
+ *
+ * Notes on signaled:
+ * May set fence->status if returning true.
+ *
+ * Notes on wait:
+ * Must not be NULL, set to dma_fence_default_wait for default implementation.
+ * the dma_fence_default_wait implementation should work for any fence, as long
+ * as enable_signaling works correctly.
+ *
+ * Must return -ERESTARTSYS if the wait is intr = true and the wait was
+ * interrupted, and remaining jiffies if fence has signaled, or 0 if wait
+ * timed out. Can also return other error values on custom implementations,
+ * which should be treated as if the fence is signaled. For example a hardware
+ * lockup could be reported like that.
+ *
+ * Notes on release:
+ * Can be NULL, this function allows additional commands to run on
+ * destruction of the fence. Can be called from irq context.
+ * If pointer is set to NULL, kfree will get called instead.

- * Memory devices:	The individual DRAM chips on a memory stick.  These
- *			devices commonly output 4 and 8 bits each (x4, x8).
- *			Grouping several of these in parallel provides the
- *			number of bits that the memory controller expects:
- *			typically 72 bits, in order to provide 64 bits +
- *			8 bits of ECC data.
- *
- * Memory Stick:	A printed circuit board that aggregates multiple
- *			memory devices in parallel.  In general, this is the
- *			Field Replaceable Unit (FRU) which gets replaced, in
- *			the case of excessive errors. Most often it is also
- *			called DIMM (Dual Inline Memory Module).
- *
- * Memory Socket:	A physical connector on the motherboard that accepts
- *			a single memory stick. Also called as "slot" on several
- *			datasheets.
- *
- * Channel:		A memory controller channel, responsible to communicate
- *			with a group of DIMMs. Each channel has its own
- *			independent control (command) and data bus, and can
- *			be used independently or grouped with other channels.
- *
- * Branch:		It is typically the highest hierarchy on a
- *			Fully-Buffered DIMM memory controller.
- *			Typically, it contains two channels.
- *			Two channels at the same branch can be used in single
- *			mode or in lockstep mode.
- *			When lockstep is enabled, the cacheline is doubled,
- *			but it generally brings some performance penalty.
- *			Also, it is generally not possible to point to just one
- *			memory stick when an error occurs, as the error
- *			correction code is calculated using two DIMMs instead
- *			of one. Due to that, it is capable of correcting more
- *			errors than on single mode.
- *
- * Single-channel:	The data accessed by the memory controller is contained
- *			into one dimm only. E. g. if the data is 64 bits-wide,
- *			the data flows to the CPU using one 64 bits parallel
- *			access.
- *			Typically used with SDR, DDR, DDR2 and DDR3 memories.
- *			FB-DIMM and RAMBUS use a different concept for channel,
- *			so this concept doesn't apply there.
- *
- * Double-channel:	The data size accessed by the memory controller is
- *			interlaced into two dimms, accessed at the same time.
- *			E. g. if the DIMM is 64 bits-wide (72 bits with ECC),
- *			the data flows to the CPU using a 128 bits parallel
- *			access.
- *
- * Chip-select row:	This is the name of the DRAM signal used to select the
- *			DRAM ranks to be accessed. Common chip-select rows for
- *			single channel are 64 bits, for dual channel 128 bits.
- *			It may not be visible by the memory controller, as some
- *			DIMM types have a memory buffer that can hide direct
- *			access to it from the Memory Controller.
- *
- * Single-Ranked stick:	A Single-ranked stick has 1 chip-select row of memory.
- *			Motherboards commonly drive two chip-select pins to
- *			a memory stick. A single-ranked stick, will occupy
- *			only one of those rows. The other will be unused.
- *
- * Double-Ranked stick:	A double-ranked stick has two chip-select rows which
- *			access different sets of memory devices.  The two
- *			rows cannot be accessed concurrently.
- *
- * Double-sided stick:	DEPRECATED TERM, see Double-Ranked stick.
- *			A double-sided stick has two chip-select rows which
- *			access different sets of memory devices. The two
- *			rows cannot be accessed concurrently. "Double-sided"
- *			is irrespective of the memory devices being mounted
- *			on both sides of the memory stick.
- *
- * Socket set:		All of the memory sticks that are required for
- *			a single memory access or all of the memory sticks
- *			spanned by a chip-select row.  A single socket set
- *			has two chip-select rows and if double-sided sticks
- *			are used these will occupy those chip-select rows.
- *
- * Bank:		This term is avoided because it is unclear when
- *			needing to distinguish between chip-select rows and
- *			socket sets.

- * in the first wait() or add_callback() path to let the fence
- * implementation know that there is another driver waiting on
- * the signal (ie. hw->sw case).
- *
- * This function can be called called from atomic context, but not
- * from irq context, so normal spinlocks can be used.
- *
- * A return value of false indicates the fence already passed,
- * or some failure occurred that made it impossible to enable
- * signaling. True indicates successful enabling.
- *
- * fence->status may be set in enable_signaling, but only when false is
- * returned.
- *
- * Calling fence_signal before enable_signaling is called allows
- * for a tiny race window in which enable_signaling is called during,
- * before, or after fence_signal. To fight this, it is recommended
- * that before enable_signaling returns true an extra reference is
- * taken on the fence, to be released when the fence is signaled.
- * This will mean fence_signal will still be called twice, but
- * the second time will be a noop since it was already signaled.
- *
- * Notes on signaled:
- * May set fence->status if returning true.
- *
- * Notes on wait:
- * Must not be NULL, set to fence_default_wait for default implementation.
- * the fence_default_wait implementation should work for any fence, as long
- * as enable_signaling works correctly.
- *
- * Must return -ERESTARTSYS if the wait is intr = true and the wait was
- * interrupted, and remaining jiffies if fence has signaled, or 0 if wait
- * timed out. Can also return other error values on custom implementations,
- * which should be treated as if the fence is signaled. For example a hardware
- * lockup could be reported like that.
- *
- * Notes on release:
- * Can be NULL, this function allows additional commands to run on
- * destruction of the fence. Can be called from irq context.
- * If pointer is set to NULL, kfree will get called instead.

- * The below are the various read and write flags that we support. Some of
- * them include behavioral modifiers that send information down to the
- * block layer and IO scheduler. They should be used along with a req_op.
- * Terminology:
- *
- *	The block layer uses device plugging to defer IO a little bit, in
- *	the hope that we will see more IO very shortly. This increases
- *	coalescing of adjacent IO and thus reduces the number of IOs we
- *	have to send to the device. It also allows for better queuing,
- *	if the IO isn't mergeable. If the caller is going to be waiting
- *	for the IO, then he must ensure that the device is unplugged so
- *	that the IO is dispatched to the driver.
- *
- *	All IO is handled async in Linux. This is fine for background
- *	writes, but for reads or writes that someone waits for completion
- *	on, we want to notify the block layer and IO scheduler so that they
- *	know about it. That allows them to make better scheduling
- *	decisions. So when the below references 'sync' and 'async', it
- *	is referencing this priority hint.
- *
- * With that in mind, the available types are:
- *
- * READ			A normal read operation. Device will be plugged.
- * READ_SYNC		A synchronous read. Device is not plugged, caller can
- *			immediately wait on this read without caring about
- *			unplugging.
- * WRITE		A normal async write. Device will be plugged.
- * WRITE_SYNC		Synchronous write. Identical to WRITE, but passes down
- *			the hint that someone will be waiting on this IO
- *			shortly. The write equivalent of READ_SYNC.
- * WRITE_ODIRECT	Special case write for O_DIRECT only.
- * WRITE_FLUSH		Like WRITE_SYNC but with preceding cache flush.
- * WRITE_FUA		Like WRITE_SYNC but data is guaranteed to be on
- *			non-volatile media on completion.
- * WRITE_FLUSH_FUA	Combination of WRITE_FLUSH and FUA. The IO is preceded
- *			by a cache flush and data is guaranteed to be on
- *			non-volatile media on completion.

+ *       teardown to inform the LLDD that the localport has been deleted.
+ *       Entrypoint is Mandatory.
+ *
+ * @remoteport_delete:  The LLDD initiates deletion of a remoteport via
+ *       nvme_fc_deregister_remoteport(). However, the teardown is
+ *       asynchronous. This routine is called upon the completion of the
+ *       teardown to inform the LLDD that the remoteport has been deleted.
+ *       Entrypoint is Mandatory.
+ *
+ * @create_queue:  Upon creating a host<->controller association, queues are
+ *       created such that they can be affinitized to cpus/cores. This
+ *       callback into the LLDD to notify that a controller queue is being
+ *       created.  The LLDD may choose to allocate an associated hw queue
+ *       or map it onto a shared hw queue. Upon return from the call, the
+ *       LLDD specifies a handle that will be given back to it for any
+ *       command that is posted to the controller queue.  The handle can
+ *       be used by the LLDD to map quickly to the proper hw queue for
+ *       command execution.  The mask of cpu's that will map to this queue
+ *       at the block-level is also passed in. The LLDD should use the
+ *       queue id and/or cpu masks to ensure proper affinitization of the
+ *       controller queue to the hw queue.
+ *       Entrypoint is Optional.
+ *
+ * @delete_queue:  This is the inverse of the crete_queue. During
+ *       host<->controller association teardown, this routine is called
+ *       when a controller queue is being terminated. Any association with

+ *       hw queue should be torn down.
+ *       Entrypoint is Optional.
+ *
+ * @poll_queue:  Called to poll for the completion of an io on a blk queue.
+ *       Entrypoint is Optional.
+ *
+ * @ls_req:  Called to issue a FC-NVME FC-4 LS service request.
+ *       The nvme_fc_ls_req structure will fully describe the buffers for
+ *       the request payload and where to place the response payload. The
+ *       LLDD is to allocate an exchange, issue the LS request, obtain the
+ *       LS response, and call the "done" routine specified in the request
+ *       structure (argument to done is the ls request structure itself).
+ *       Entrypoint is Mandatory.
+ *
+ * @fcp_io:  called to issue a FC-NVME I/O request.  The I/O may be for
+ *       an admin queue or an i/o queue.  The nvmefc_fcp_req structure will
+ *       fully describe the io: the buffer containing the FC-NVME CMD IU
+ *       (which contains the SQE), the sg list for the payload if applicable,
+ *       and the buffer to place the FC-NVME RSP IU into.  The LLDD will
+ *       complete the i/o, indicating the amount of data transferred or
+ *       any transport error, and call the "done" routine specified in the
+ *       request structure (argument to done is the fcp request structure
+ *       itself).
+ *       Entrypoint is Mandatory.
+ *
+ * @ls_abort: called to request the LLDD to abort the indicated ls request.
+ *       The call may return before the abort has completed. After aborting
+ *       the request, the LLDD must still call the ls request done routine
+ *       indicating an FC transport Aborted status.
+ *       Entrypoint is Mandatory.
+ *
+ * @fcp_abort: called to request the LLDD to abort the indicated fcp request.

+ *       indicating an FC transport Aborted status.
+ *       Entrypoint is Mandatory.
+ *

+ *       supports for cpu affinitization.
+ *       Value is Mandatory. Must be at least 1.
+ *
+ * @max_sgl_segments:  indicates the maximum number of sgl segments supported
+ *       by the LLDD
+ *       Value is Mandatory. Must be at least 1. Recommend at least 256.
+ *
+ * @max_dif_sgl_segments:  indicates the maximum number of sgl segments

+ * struct nvmefc_tgt_fcp_req - Structure used between LLDD and NVMET-FC
+ *                            layer to represent the exchange context and
+ *                            the specific FC-NVME IU operation(s) to perform
+ *                            for a FC-NVME FCP IO.
+ *
+ * Structure used between LLDD and nvmet-fc layer to represent the exchange
+ * context for a FC-NVME FCP I/O operation (e.g. a nvme sqe, the sqe-related
+ * memory transfers, and its assocated cqe transfer).
+ *
+ * The structure is allocated by the LLDD whenever a FCP CMD IU is received
+ * from the FC link. The address of the structure is passed to the nvmet-fc
+ * layer via the nvmet_fc_rcv_fcp_req() call. The address of the structure
+ * will be passed back to the LLDD for the data operations and transmit of
+ * the response. The LLDD is to use the address to map back to the LLDD
+ * exchange structure which maintains information such as the targetport
+ * the FCP I/O was received on, the remote FC NVME initiator that sent the
+ * FCP I/O, and any FC exchange context.  Upon completion of the FCP target
+ * operation, the address of the structure will be passed back to the FCP
+ * op done() routine, allowing the nvmet-fc layer to release dma resources.
+ * Upon completion of the done() routine for either RSP or ABORT ops, no
+ * further access will be made by the nvmet-fc layer and the LLDD can
+ * de-allocate the structure.
+ *
+ * Field initialization:
+ *   At the time of the nvmet_fc_rcv_fcp_req() call, there is no content that
+ *     is valid in the structure.
+ *
+ *   When the structure is used for an FCP target operation, the nvmet-fc
+ *     layer will fully set the fields in order to specify the scattergather
+ *     list, the transfer length, as well as the done routine to be called
+ *     upon compeletion of the operation.  The nvmet-fc layer will also set a
+ *     private pointer for its own use in the done routine.
+ *
+ * Note: the LLDD must never fail a NVMET_FCOP_ABORT request !!
+ *
+ * Values set by the NVMET-FC layer prior to calling the LLDD fcp_op
+ * entrypoint.
+ * @op:       Indicates the FCP IU operation to perform (see NVMET_FCOP_xxx)
+ * @hwqid:    Specifies the hw queue index (0..N-1, where N is the
+ *            max_hw_queues value from the LLD's nvmet_fc_target_template)
+ *            that the operation is to use.
+ * @offset:   Indicates the DATA_OUT/DATA_IN payload offset to be tranferred.
+ *            Field is only valid on WRITEDATA, READDATA, or READDATA_RSP ops.
+ * @timeout:  amount of time, in seconds, to wait for a response from the NVME
+ *            host. A value of 0 is an infinite wait.
+ *            Valid only for the following ops:
+ *              WRITEDATA: caps the wait for data reception
+ *              READDATA_RSP & RSP: caps wait for FCP_CONF reception (if used)
+ * @transfer_length: the length, in bytes, of the DATA_OUT or DATA_IN payload
+ *            that is to be transferred.
+ *            Valid only for the WRITEDATA, READDATA, or READDATA_RSP ops.
+ * @ba_rjt:   Contains the BA_RJT payload that is to be transferred.
+ *            Valid only for the NVMET_FCOP_BA_RJT op.
+ * @sg:       Scatter/gather list for the DATA_OUT/DATA_IN payload data.
+ *            Valid only for the WRITEDATA, READDATA, or READDATA_RSP ops.
+ * @sg_cnt:   Number of valid entries in the scatter/gather list.
+ *            Valid only for the WRITEDATA, READDATA, or READDATA_RSP ops.

+ *       asynchronous. This routine is called upon the completion of the
+ *       teardown to inform the LLDD that the targetport has been deleted.
+ *       Entrypoint is Mandatory.
+ *
+ * @xmt_ls_rsp:  Called to transmit the response to a FC-NVME FC-4 LS service.
+ *       The nvmefc_tgt_ls_req structure is the same LLDD-supplied exchange
+ *       structure specified in the nvmet_fc_rcv_ls_req() call made when
+ *       the LS request was received.  The structure will fully describe
+ *       the buffers for the response payload and the dma address of the
+ *       payload. The LLDD is to transmit the response (or return a non-zero
+ *       errno status), and upon completion of the transmit, call the
+ *       "done" routine specified in the nvmefc_tgt_ls_req structure
+ *       (argument to done is the ls reqwuest structure itself).
+ *       After calling the done routine, the LLDD shall consider the
+ *       LS handling complete and the nvmefc_tgt_ls_req structure may
+ *       be freed/released.
+ *       Entrypoint is Mandatory.
+ *
+ * @fcp_op:  Called to perform a data transfer, transmit a response, or
+ *       abort an FCP opertion. The nvmefc_tgt_fcp_req structure is the same
+ *       LLDD-supplied exchange structure specified in the
+ *       nvmet_fc_rcv_fcp_req() call made when the FCP CMD IU was received.
+ *       The op field in the structure shall indicate the operation for
+ *       the LLDD to perform relative to the io.
+ *         NVMET_FCOP_READDATA operation: the LLDD is to send the
+ *           payload data (described by sglist) to the host in 1 or
+ *           more FC sequences (preferrably 1).  Note: the fc-nvme layer
+ *           may call the READDATA operation multiple times for longer
+ *           payloads.
+ *         NVMET_FCOP_WRITEDATA operation: the LLDD is to receive the
+ *           payload data (described by sglist) from the host via 1 or
+ *           more FC sequences (preferrably 1). The LLDD is to generate
+ *           the XFER_RDY IU(s) corresponding to the data being requested.
+ *           Note: the FC-NVME layer may call the WRITEDATA operation
+ *           multiple times for longer payloads.
+ *         NVMET_FCOP_READDATA_RSP operation: the LLDD is to send the
+ *           payload data (described by sglist) to the host in 1 or
+ *           more FC sequences (preferrably 1). If an error occurs during
+ *           payload data transmission, the LLDD is to set the
+ *           nvmefc_tgt_fcp_req fcp_error and transferred_length field, then
+ *           consider the operation complete. On error, the LLDD is to not
+ *           transmit the FCP_RSP iu. If all payload data is transferred
+ *           successfully, the LLDD is to update the nvmefc_tgt_fcp_req
+ *           transferred_length field and may subsequently transmit the
+ *           FCP_RSP iu payload (described by rspbuf, rspdma, rsplen).
+ *           The LLDD is to await FCP_CONF reception to confirm the RSP
+ *           reception by the host. The LLDD may retramsit the FCP_RSP iu
+ *           if necessary per FC-NVME. Upon reception of FCP_CONF, or upon
+ *           FCP_CONF failure, the LLDD is to set the nvmefc_tgt_fcp_req
+ *           fcp_error field and consider the operation complete..
+ *         NVMET_FCOP_RSP: the LLDD is to transmit the FCP_RSP iu payload
+ *           (described by rspbuf, rspdma, rsplen).  The LLDD is to await
+ *           FCP_CONF reception to confirm the RSP reception by the host.
+ *           The LLDD may retramsit the FCP_RSP iu if necessary per FC-NVME.
+ *           Upon reception of FCP_CONF, or upon FCP_CONF failure, the
+ *           LLDD is to set the nvmefc_tgt_fcp_req fcp_error field and
+ *           consider the operation complete..
+ *         NVMET_FCOP_ABORT: the LLDD is to terminate the exchange
+ *           corresponding to the fcp operation. The LLDD shall send
+ *           ABTS and follow FC exchange abort-multi rules, including
+ *           ABTS retries and possible logout.
+ *       Upon completing the indicated operation, the LLDD is to set the
+ *       status fields for the operation (tranferred_length and fcp_error
+ *       status) in the request, then all the "done" routine
+ *       indicated in the fcp request.  Upon return from the "done"
+ *       routine for either a NVMET_FCOP_RSP or NVMET_FCOP_ABORT operation
+ *       the fc-nvme layer will not longer reference the fcp request,
+ *       allowing the LLDD to free/release the fcp request.
+ *       Note: when calling the done routine for READDATA or WRITEDATA
+ *       operations, the fc-nvme layer may immediate convert, in the same
+ *       thread and before returning to the LLDD, the fcp operation to
+ *       the next operation for the fcp io and call the LLDDs fcp_op
+ *       call again. If fields in the fcp request are to be accessed post
+ *       the done call, the LLDD should save their values prior to calling
+ *       the done routine, and inspect the save values after the done
+ *       routine.
+ *       Returns 0 on success, -<errno> on failure (Ex: -EIO)
+ *       Entrypoint is Mandatory.
+ *
+ * @max_hw_queues:  indicates the maximum number of hw queues the LLDD
+ *       supports for cpu affinitization.
+ *       Value is Mandatory. Must be at least 1.
+ *
+ * @max_sgl_segments:  indicates the maximum number of sgl segments supported
+ *       by the LLDD
+ *       Value is Mandatory. Must be at least 1. Recommend at least 256.
+ *
+ * @max_dif_sgl_segments:  indicates the maximum number of sgl segments
+ *       supported by the LLDD for DIF operations.
+ *       Value is Mandatory. Must be at least 1. Recommend at least 256.
+ *
+ * @dma_boundary:  indicates the dma address boundary where dma mappings
+ *       will be split across.
+ *       Value is Mandatory. Typical value is 0xFFFFFFFF to split across
+ *       4Gig address boundarys
+ *
+ * @target_features: The LLDD sets bits in this field to correspond to
+ *       optional features that are supported by the LLDD.
+ *       Refer to the NVMET_FCTGTFEAT_xxx values.
+ *       Value is Mandatory. Allowed to be zero.
+ *
+ * @target_priv_sz: The LLDD sets this field to the amount of additional
+ *       memory that it would like fc nvme layer to allocate on the LLDD's
+ *       behalf whenever a targetport is allocated.  The additional memory
+ *       area solely for the of the LLDD and its location is specified by
