A UHS setting of SDR25 can give better results for High Speed mode.
This is because there is no setting corresponding to high speed. Currently
SDHCI sets no value, which means zero which is also the setting for SDR12.
There was an attempt to change this in sdhci.c but it caused problems for
some drivers, so it was reverted and the change was made to sdhci-brcmstb
in commit 2fefc7c5f7d16e ("mmc: sdhci-brcmstb: Fix incorrect switch to HS
mode"). Several other drivers also do this.

Currently, scan_microcode() leverages microcode_matches() to check
if the microcode matches the CPU by comparing the family and model.
However, the processor stepping and flags of the microcode signature
should also be considered when saving a microcode patch for early
update.
Use find_matching_signature() in scan_microcode() and get rid of the
now-unused microcode_matches() which is a good cleanup in itself.
Complete the verification of the patch being saved for early loading in
save_microcode_patch() directly. This needs to be done there too because
save_mc_for_early() will call save_microcode_patch() too.
The second reason why this needs to be done is because the loader still
tries to support, at least hypothetically, mixed-steppings systems and
thus adds all patches to the cache that belong to the same CPU model
albeit with different steppings.
For example:
microcode: CPU: sig=0x906ec, pf=0x2, rev=0xd6
microcode: mc_saved[0]: sig=0x906e9, pf=0x2a, rev=0xd6, total size=0x19400, date = 2020-04-23
microcode: mc_saved[1]: sig=0x906ea, pf=0x22, rev=0xd6, total size=0x19000, date = 2020-04-27
microcode: mc_saved[2]: sig=0x906eb, pf=0x2, rev=0xd6, total size=0x19400, date = 2020-04-23
microcode: mc_saved[3]: sig=0x906ec, pf=0x22, rev=0xd6, total size=0x19000, date = 2020-04-27
microcode: mc_saved[4]: sig=0x906ed, pf=0x22, rev=0xd6, total size=0x19400, date = 2020-04-23
The patch which is being saved for early loading, however, can only be
the one which fits the CPU this runs on so do the signature verification
before saving.

and rewrite commit message. ]

Commit dd461cd9183f ("opp: Allow dev_pm_opp_get_opp_table() to return
-EPROBE_DEFER") handles -EPROBE_DEFER for the clock/interconnects within
_allocate_opp_table() which is called from dev_pm_opp_add and it
now propagates the error back to the caller.
SCMI performance domain re-used clock bindings to keep it simple. However
with the above mentioned change, if clock property is present in a device
node, opps fails to get added with below errors until clk_get succeeds.
cpu0: failed to add opp 450000000Hz
cpu0: failed to add opps to the device
....(errors on cpu1-cpu4)
cpu5: failed to add opp 450000000Hz
cpu5: failed to add opps to the device
So, in order to fix the issue, we need to register dummy clock provider.
With the dummy clock provider, clk_get returns NULL(no errors!), then opp
core proceeds to add OPPs for the CPUs.

Commit b89c01c96051 ("cpufreq: tegra186: Fix initial frequency")
implemented the CPUFREQ 'get' callback to determine the current
operating frequency for each CPU. This implementation used a simple
looked up to determine the current operating frequency. The problem
with this is that frequency table for different Tegra186 devices may
vary and so the default boot frequency for Tegra186 device may or may
not be present in the frequency table. If the default boot frequency is
not present in the frequency table, this causes the function
tegra186_cpufreq_get() to return 0 and in turn causes cpufreq_online()
to fail which prevents CPUFREQ from working.
Fix this by always calculating the CPU frequency based upon the current
'ndiv' setting for the CPU. Note that the CPU frequency for Tegra186 is
calculated by reading the current 'ndiv' setting, multiplying by the
CPU reference clock and dividing by a constant divisor.

Maurizio found a race where the abort and cmd stop paths can race as
follows:
1. thread1 runs iscsit_release_commands_from_conn and sets
CMD_T_FABRIC_STOP.
2. thread2 runs iscsit_aborted_task and then does __iscsit_free_cmd. It
then returns from the aborted_task callout and we finish
target_handle_abort and do:
target_handle_abort -> transport_cmd_check_stop_to_fabric ->
lio_check_stop_free -> target_put_sess_cmd
The cmd is now freed.
3. thread1 now finishes iscsit_release_commands_from_conn and runs
iscsit_free_cmd while accessing a command we just released.
In __target_check_io_state we check for CMD_T_FABRIC_STOP and set the
CMD_T_ABORTED if the driver is not cleaning up the cmd because of a session
shutdown. However, iscsit_release_commands_from_conn only sets the
CMD_T_FABRIC_STOP and does not check to see if the abort path has claimed
completion ownership of the command.
This adds a check in iscsit_release_commands_from_conn so only the abort or
fabric stop path cleanup the command.

iSCSI NOPs are sometimes "lost", mistakenly sent to the user-land iscsid
daemon instead of handled in the kernel, as they should be, resulting in a
message from the daemon like:
iscsid: Got nop in, but kernel supports nop handling.
This can occur because of the new forward- and back-locks, and the fact
that an iSCSI NOP response can occur before processing of the NOP send is
complete. This can result in "conn->ping_task" being NULL in
iscsi_nop_out_rsp(), when the pointer is actually in the process of being
set.
To work around this, we add a new state to the "ping_task" pointer. In
addition to NULL (not assigned) and a pointer (assigned), we add the state
"being set", which is signaled with an INVALID pointer (using "-1").

bnxt_add_one_ctr() adds a hardware counter to a software counter and
adjusts for the hardware counter wraparound against the mask. The logic
assumes that the hardware counter is always smaller than or equal to
the mask.
This assumption is mostly correct. But in some cases if the firmware
is older and does not provide the accurate mask, the driver can use
a mask that is smaller than the actual hardware mask. This can cause
some extra carry bits to be added to the software counter, resulting in
counters that far exceed the actual value. Fix it by masking the
hardware counter with the mask passed into bnxt_add_one_ctr().

Transactions sit on one of several lists, depending on their state
(allocated, pending, complete, or polled). A spinlock protects
against concurrent access when transactions are moved between these
lists.
Transactions are also reference counted. A newly-allocated
transaction has an initial count of 1; a transaction is released in
gsi_trans_free() only if its decremented reference count reaches 0.
Releasing a transaction includes removing it from the polled (or if
unused, allocated) list, so the spinlock is acquired when we release
a transaction.
The reference count is used to allow a caller to synchronously wait
for a committed transaction to complete. In this case, the waiter
takes an extra reference to the transaction *before* committing it
(so it won't be freed), and releases its reference (calls
gsi_trans_free()) when it is done with it.
Similarly, gsi_channel_update() takes an extra reference to ensure a
transaction isn't released before the function is done operating on
it. Until the transaction is moved to the completed list (by this
function) it won't be freed, so this reference is taken "safely."
But in the quiesce path, we want to wait for the "last" transaction,
which we find in the completed or polled list. Transactions on
these lists can be freed at any time, so we (try to) prevent that
by taking the reference while holding the spinlock.
Currently gsi_trans_free() decrements a transaction's reference
count unconditionally, acquiring the lock to remove the transaction
from its list *only* when the count reaches 0. This does not
protect the quiesce path, which depends on the lock to ensure its
extra reference prevents release of the transaction.
Fix this by only dropping the last reference to a transaction
in gsi_trans_free() while holding the spinlock.

Around one third of the fixes this time are for dts files that list
their ethernet controller as using 'phy-mode="rgmii"' but are changed to
'phy-mode="rgmii-id"' now, because the PHY drivers (realtek, ksz9031,
dp83867, ...) now configure the internal delay based on that when they
used to stay on the hardware default.
The long story is archived at
https://lore.kernel.org/netdev/CAMj1kXEEF_Un-4NTaD5iUN0NoZYaJQn-rPediX0S6oRiuVuW-A@mail.gmail.com/
I was trying to hold off on the bugfixes until there was a solution that
would avoid breaking all boards, but that does not seem to be happening
any time soon, so I am now sending the correct version of the dts files to
ensure that at least these machines can use their network devices again.
The other changes this time are:
- Updating the MAINTAINER lists for Allwinner and Samsung SoCs
- Multiple i.MX8MN machines get updates for their CPU
operating points to match the data sheet
- A revert for a dts patch that caused a regression in USB
support on Odroid U3
- Two fixes for the AMD Tee driver, addressing a memory leak
and missing locking

Pull ARM SoC fixes from Arnd Bergmann:
"Around one third of the fixes this time are for dts files that list
their ethernet controller as using 'phy-mode="rgmii"' but are changed
to 'phy-mode="rgmii-id"' now, because the PHY drivers (realtek,
ksz9031, dp83867, ...) now configure the internal delay based on that
when they used to stay on the hardware default.
The long story is archived at
https://lore.kernel.org/netdev/CAMj1kXEEF_Un-4NTaD5iUN0NoZYaJQn-rPediX0S6oRiuVuW-A@mail.gmail.com/
I was trying to hold off on the bugfixes until there was a solution
that would avoid breaking all boards, but that does not seem to be
happening any time soon, so I am now sending the correct version of
the dts files to ensure that at least these machines can use their
network devices again.
The other changes this time are:
- Updating the MAINTAINER lists for Allwinner and Samsung SoCs
- Multiple i.MX8MN machines get updates for their CPU operating
points to match the data sheet
- A revert for a dts patch that caused a regression in USB support on
Odroid U3
- Two fixes for the AMD Tee driver, addressing a memory leak and
missing locking
- Mark the network subsystem on qoriq-fman3 as cache coherent for
correctness as better performance.
- Minor dts fixes elsewhere, addressing dtc warnings and similar
problems"

lantiq,xrx200-net 1e10b308.eth eth0: error -19 setting up slave phy
This is a single-port board using the internal Fast Ethernet PHY. The
user reports that switching to PHY scanning instead of configuring the
PHY within device-tree works around this issue.
The documentation for the standalone variant of the PHY11G (which is
probably very similar to what is used inside the xRX200 SoCs but having
the firmware burnt onto that standalone chip in the factory) states that
the PHY needs 300ms to be ready for MDIO communication after releasing
the reset.
Add a 300ms delay after initializing all GPHYs to ensure that the GPHY
firmware had enough time to initialize and to appear on the MDIO bus.
Unfortunately there is no (known) documentation on what the minimum time
to wait after releasing the reset on an internal PHY so play safe and
take the one for the external variant. Only wait after the last GPHY
firmware is loaded to not slow down the initialization too much (
xRX200 has two GPHYs but newer SoCs have at least three GPHYs).

We catch the case where we enter generic_file_buffered_read() with data
already transferred, but we also need to be careful not to allow an async
page lock if we're looping transferring data. If not, we could be
returning -EIOCBQUEUED instead of the transferred amount, and it could
result in double waitqueue additions as well.
