net/mlx5e: Move IPSec policy check after decryption
This series by Jianbo adds IPsec policy check after decryption.
In current mlx5 driver, the policy check is done before decryption for
IPSec crypto and packet offload. This series changes that order to
make it consistent with the processing in kernel xfrm. Besides, RX
state with UPSPEC selector is supported correctly after new steering
table is added after decryption and before the policy check.

Previously, the upper layer matches are added for the decryption rule
when xfrm selector's UPSPEC is specified in the command. However, it's
impossible as packets are not decrypted, and there is no way to do
match on the upper protocol (TCP/UDP) with specific source/destination
port. The result is that packets are not decrypted by hardware because
of this mismatch. Instead, they are forwarded to kernel, and
decryption is done by software.
To resolve this issue, this patch adds new table (sa_sel) after status
table and before policy table. When UPSPEC's proto is specified in
xfrm state's selector, a rule is added in status table to forward the
decrypted packets to sa_sel table, where the corresponding rule for
selector's UPSPEC is added, and packet's upper headers are checked
there. If matched, they will be forward to policy table to do policy
check. Otherwise, they are dropped immediately.
Besides, add a global count for this kind of packet drop.

For crypto offload, there is no xfrm policy rule offloaded to
hardware, so no need to continue with policy check for it.
Previously, for crypto offload, the hardware metadata reg c4 is not
used and not changed, but set to ASO_OK(0) before decryption to avoid
garbage data. Then a default rule is added to check ipsec_syndrome and
this register. Packets are forwarded to policy table if succeed, or
drop if fails.
According to hardware document, this register value could be 0, 1.
So a special value (0xAA), which is not used by hardware, is chosen as
an indication for crypto offload. It is set to c4 before decryption.
Then a default rule, which matches on 0xAA (and ipsec_syndrome on 0),
is added, which means packets are done by crypto offload, and
sends them to kernel directly, thus skips the policy check.

Currently, xfrm policy check is done before decryption in mlx5 driver.
If matching any policy, packets are forwarded to xfrm state table for
decryption. But this is exact opposite to what software does. For
kernel implementation, xfrm decode is unconditionally activated
whenever an IPSec packet reaches the input flow if there’s a matching
state rule.
This patch changes the order, move policy check after decryption.
Besides, a miss flow table is added at the end for legacy mode, to
make it easier to update the default destination of the steering rules.
So ESP packets are firstly forwarded to SA table for decryption, then
the result is checked in status table. If the decryption succeeds,
packets are forwarded to another table to check xfrm policy rules.
When a policy with allow action is matched, if in legacy mode packets
are forwarded to miss flow table with one rule to forward them to RoCE
tables, if in switchdev mode they are forwarded directly to TC root
chain instead.

For eswitch in legacy mode, the packets decrypted in RX SA table will

Function stop_qc_helper() is called while the debug_scsi_cmd lock is held,
and from here we may call cancel_work_sync(), which may sleep.
Sleeping in atomic sections is not allowed.
Hence change the cancel_work_sync() call into a cancel_work() call.
However now it is not possible to know if the work callback is running when
we return. This is relevant for eh_abort_handler handling, as the semantics
of that callback are that success means that we do not keep a reference to
the scsi_cmnd - now this is not possible. So return FAIL when we are unsure
if the callback still running.

Admin reply processing can be called from multiple contexts. The driver
uses an atomic flag for synchronization among multiple threads/context for
draining the admin replies.
Upon entering the admin processing routine, the driver will set the atomic
flag and start reply processing. When exiting the routine, the driver
resets the flag. However, there is a race condition when one thread (Thread
1) has processed replies and is about to reset the flag but in the meantime
few more replies are posted and another thread (Thread 2) is called to
process replies. Since the synchronization flag is still set, Thread 2 will
return without processing replies and those new replies will not be
flushed.
Make the watchdog thread monitor cases where admin ISR/poll call returns
due to another thread processing admin replies. If such an instance is
found, make driver call admin ISR to drain replies (if any).

There are conditions, albeit somewhat unlikely, under which right hand
expressions, calculating the end of time period in functions like
repaper_frame_fixed_repeat(), may overflow.
For instance, if 'factor10x' in repaper_get_temperature() is high
enough (170), as is 'epd->stage_time' in repaper_probe(), then the
resulting value of 'end' will not fit in unsigned int expression.
Mitigate this by casting 'epd->factored_stage_time' to wider type before
any multiplication is done.

this regulator triggers the warning message from kernel as driver
uses a fallback dummy regulator when there is no regulator assigned.

Add a missing voltage regulator of 1.8v to the sn65dsi83
(dsi_lvds bridge) node. Due to the absence of this regulator, a fallback
dummy regulator is used and that triggers a warning message from the
kernel. Assigning the appropriate regulator avoids the warning.

Remove device tree property "fsl,magic-packet" as WoL is not working
on the SoM and so not required. This also saves a significant amount of
power during suspend as the ethernet phy is not powered down otherwise.

Not using pull-up on the host wake-up line triggers the wake up
immediately after device enters suspend. Fix this by enabling internal
pull-up and setting interrupt triggering on the falling edge.

LDO3 is also used as switch for enabling VDD_3V3_S and need to
be kept on during suspend. Disabling this can lead to an unwanted
reset during resume.
Set LDO3 to 2,5V as the voltage should be fix.

Remove LVDS panel and backlight nodes from the Verdin iMX8M Mini SoM
dtsi file, those two hardware components are not part of the SoM,
therefore they should not be present in this file.
This is solving a dtb checker warning about panel-lvds compatible.
