Lee Jones 083645bab2 scsi: pm8001: Fix a bunch of kerneldoc issues
Provide lots of missing descriptions, remove some superfluous ones
(probably due to docrot) and demote one header which does not provide many
descriptions, and the ones it does provide are incorrect.

Hannes Reinecke e73a5e8e80 scsi: core: Only return started requests from scsi_host_find_tag()
scsi_host_find_tag() is used by the drivers to return a scsi command based
on the command tag. Typically it's used from the interrupt handler to fetch
the command associated with a value returned from hardware. Some drivers
like fnic or qla4xxx, however, also use it also to traverse outstanding
commands.  With the current implementation scsi_host_find_tag() will return
commands even if they are not started (i.e. passed to the driver).  This
will result in random errors with those drivers.  With this patch
scsi_host_find_tag() will only return 'started' commands (i.e. commands
which have been passed to the drivers) thus avoiding the above issue.  The
other use cases will be unaffected as the interrupt handler naturally will
only ever return 'started' requests.

In theory, a panic can happen after a bus or host reset with dma_started
flag set. Fix this by halting the DMA before reinitializing the host.
Don't assume that ms->current_req is set when halt_dma() is invoked as it
may not hold for bus or host reset.

BTW, this particular Conner drive can be made to work by inhibiting
disconnect/reselect with 'mesh.resel_targets=0'.

libata currently attempts to reset even if the SATA disk is unplugged.  To
avoid the meaningless reset of a missing disk, libsas should report offline
status to libata. libata already provides a .prereset callback for this
purpose. This is called by ata_eh_reset() and can be used to influence
whether a reset attempt should be made.

Add sas_ata_preset callback to check status of phy and disk. If the disk is
already offline or phy is disabled, we return -ENOENT to libata to avoid
the reset.

Alan Stern 8f38f8e0a3 scsi: block: pm: Simplify resume handling
Commit 05d18ae1cc ("scsi: pm: Balance pm_only counter of request queue
during system resume") fixed a problem in the block layer's runtime-PM
code: blk_set_runtime_active() failed to call blk_clear_pm_only().
However, the commit's implementation was awkward; it forced the SCSI
system-resume handler to choose whether to call blk_post_runtime_resume()
or blk_set_runtime_active(), depending on whether or not the SCSI device
had previously been runtime suspended.

This patch simplifies the situation considerably by adding the missing
function call directly into blk_set_runtime_active() (under the condition
that the queue is not already in the RPM_ACTIVE state).  This allows the
SCSI routine to revert back to its original form.  Furthermore, making this
change reveals that blk_post_runtime_resume() (in its success pathway) does
exactly the same thing as blk_set_runtime_active().  The duplicate code is
easily removed by making one routine call the other.

No functional changes are intended.

Eric Biggers df4ec2fa7a scsi: ufs-qcom: Add Inline Crypto Engine support
Add support for Qualcomm Inline Crypto Engine (ICE) to ufs-qcom.

The standards-compliant parts, such as querying the crypto capabilities and
enabling crypto for individual UFS requests, are already handled by
ufshcd-crypto.c, which itself is wired into the blk-crypto framework.
However, ICE requires vendor-specific init, enable, and resume logic, and
it requires that keys be programmed and evicted by vendor-specific SMC
calls.  Make the ufs-qcom driver handle these details.

I tested this on Dragonboard 845c, which is a publicly available
development board that uses the Snapdragon 845 SoC and runs the upstream
Linux kernel.  This is the same SoC used in the Pixel 3 and Pixel 3 XL
phones.  This testing included (among other things) verifying that the
expected ciphertext was produced, both manually using ext4 encryption and
automatically using a block layer self-test I've written.

I've also tested that this driver works nearly as-is on the Snapdragon 765
and Snapdragon 865 SoCs.  And others have tested it on Snapdragon 850,
Snapdragon 855, and Snapdragon 865 (see the Tested-by tags).

This is based very loosely on the vendor-provided driver in the kernel
source code for the Pixel 3, but I've greatly simplified it.  Also, for now
I've only included support for major version 3 of ICE, since that's all I
have the hardware to test with the mainline kernel.  Plus it appears that
version 3 is easier to use than older versions of ICE.

For now, only allow using AES-256-XTS.  The hardware also declares support
for AES-128-XTS, AES-{128,256}-ECB, and AES-{128,256}-CBC (BitLocker
variant).  But none of these others are really useful, and they'd need to
be individually tested to be sure they worked properly.

This commit also changes the name of the loadable module from "ufs-qcom" to
"ufs_qcom", as this is necessary to compile it from multiple source files
(unless we were to rename ufs-qcom.c).

On Snapdragon SoCs, the Linux kernel isn't permitted to directly access the

evicting keys must be done through vendor-specific SMC calls.

To support this hardware, add a ->program_key() method to 'struct

programming / eviction procedure.

that's needed for the ufs-qcom driver to use inline encryption on
Snapdragon SoCs.  This interface consists of two SCM calls: one to program
a key into a keyslot, and one to invalidate a keyslot.

Although the UFS specification defines a standard way to do this, on these
SoCs the Linux kernel isn't permitted to access the needed crypto
configuration registers directly; these SCM calls must be used instead.
