The initial version of the RAA228228 datasheet claimed that the device
supported READ_TEMPERATURE_3 but not READ_TEMPERATURE_1. It has since been
discovered that the datasheet was incorrect. The RAA228228 does support
READ_TEMPERATURE_1 but does not support READ_TEMPERATURE_3.

After testing new YH-5151E devices, we found out that not all YH-5151E
work the same. The newly tested devices actually report vout correctly
in linear16 (even though they're still YH-5151E). We suspect that it is
because these new devices have a different firmware version, but that is
unconfirmed. The version cannot be queried through PMBus.
The compliant versions of YH-5151E report VOUT_MODE normally, so we turn
on the linear11 workaround only if VOUT_MODE doesn't report anything.

fine to go now (famous last words).

When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.
Therefore, remove the error printing here to simplify code and reduce the
binary size.

When driver is loaded after rmmod some drives are not showing up during
discovery.
SATA drives are directly attached to the controller connected phys. During
device discovery, the IDENTIFY command (qc timeout (cmd 0xec)) is timing out
during revalidation. This will trigger abort from host side and controller
successfully aborts the command and returns success. Post this successful
abort response ATA library decides to mark the disk as NODEV.
To overcome this, inside pm8001_scan_start() after phy_start() call, add get
start response and wait for few milliseconds to trigger next phy start.
This millisecond delay will give sufficient time for the controller state
machine to accept next phy start.

The controller expects all data it sends/receives to be little-endian.
Therefore, the packet struct definitions should use the __le16/32/64
types. Once those are correct, sparse reports several issues with the
driver code, which are fixed here as well.
The main issue observed was at the call to scsi_set_resid(), where the
byteswapped parameter would eventually trigger the alignment check at
drivers/scsi/sd.c:2009. At that point, the kernel would continuously
complain about an "Unaligned partial completion", and no further I/O could
occur.
This gets the controller working on big endian powerpc64.

Currently, all command packet structs used by this driver are packed.
However, only one (TW_SG_Entry) actually needs to be packed, because it
uses 64-bit addresses at 32-bit alignment. To improve the quality of
generated code, stop packing all of the other command packet structs. This
requires adjusting the type of one misaligned "reserved" member.
After this change, pahole reports that only one type had its layout change:
the tw_compat_info member of TW_Device_Extension is now naturally aligned.

The layout follows SPC-4:

- SCSI transport protocol standard
- SCSI primary command set standard
- SCSI device type command set standard
All version descriptor values are defined as "no version claimed" because

The drm_format_info() function returns NULL if the format is
unsupported, but the simplefb_get_validated_format() is expected to
return error pointers. If we propagate the NULL return then it will
lead to a NULL dereference in the callers. Swap the NULL and trade it
in for an ERR_PTR(-EINVAL).

Mitigate A-MSDU injection attacks (CVE-2020-24588) by detecting if the
destination address of a subframe equals an RFC1042 (i.e., LLC/SNAP)
header, and if so dropping the complete A-MSDU frame. This mitigates
known attacks, although new (unknown) aggregation-based attacks may
remain possible.
This defense works because in A-MSDU aggregation injection attacks, a
normal encrypted Wi-Fi frame is turned into an A-MSDU frame. This means
the first 6 bytes of the first A-MSDU subframe correspond to an RFC1042
header. In other words, the destination MAC address of the first A-MSDU
subframe contains the start of an RFC1042 header during an aggregation
attack. We can detect this and thereby prevent this specific attack.
For details, see Section 7.2 of "Fragment and Forge: Breaking Wi-Fi
Through Frame Aggregation and Fragmentation".

If rport target discovery commands fail for some reason, they get retried
up to a set number of retries. Once the retry limit is exceeded, the target
is deleted. In order to delete the target, we either need to do an implicit
logout or a move login. In the move login case, if the move login fails, we
want to retry it. This ensures the retry counter gets reinitialized so the
move login will get retried.

If fast fail is enabled and we encounter a WWPN moving from one port id to
another port id with I/O outstanding, if we use the move login MAD,
although it will work, it will leave any outstanding I/O still outstanding
to the old port id. Eventually, the SCSI command timers will fire and we
will abort these commands, however, this is generally much longer than the
fast fail timeout, which can lead to I/O operations being outstanding for a
long time. This patch changes the behavior to avoid the move login if fast
fail is enabled. Once terminate_rport_io cleans up the rport, then we force
the target back through the delete process, which re-drives the implicit
logout, then kicks us back into discovery where we will discover the WWPN
at the new location and do a PLOGI to it.

When service is being performed on an SVC with NPIV enabled, the WWPN of
the canister / node being serviced fails over to the another canister /
node. This looks to the ibmvfc driver as a WWPN moving from one SCSI ID to
another. The driver will first attempt to do an implicit logout of the old
SCSI ID. If this works, we simply delete the rport at the old location and
add an rport at the new location and the FC transport class handles
everything. However, if there is I/O outstanding, this implicit logout will
fail, in which case we will send a "move login" request to the VIOS. This
will cancel any outstanding I/O to that port, logout the port, and PLOGI
the new port. Recently we've encountered a scenario where the move login
fails. This was resulting in an attempted plogi to the new scsi id, without
the old scsi id getting logged out, which is a VIOS protocol violation. To
solve this, we want to keep tracking the old scsi id as the current scsi
id. That way, once terminate_rport_io cancels the outstanding i/o, it will
send us back through to do an implicit logout of the old scsi id, rather
than the new scsi id, and then we can plogi the new scsi id.
