PSCI is not implemented on SparX-5 at all, there is no ATF and U-boot that
is shipped does not implement it as well.
I have tried flashing the latest BSP 2022.12 U-boot which did not work.
After contacting Microchip, they confirmed that there is no ATF for the
SoC nor PSCI implementation which is unfortunate in 2023.
So, disable PSCI as otherwise kernel crashes as soon as it tries probing
PSCI with, and the crash is only visible if earlycon is used.
Since PSCI is not implemented, switch core bringup to use spin-tables
which are implemented in the vendor U-boot and actually work.

When running large numbers of pppoe connections, a bucket size of 16 may
be too small and 256 may be more appropriate. This sacrifices some RAM
but should result in faster processing of incoming PPPoE frames.
On our systems we run upwards of 150 PPPoE connections at any point in
time, and we suspect we're starting to see the effects of this small
number of buckets.
The legal values according to pppoe.c is anything that when 8 is divided
by that results in a modulo of 0, ie, 1, 2, 4 and 8.
The size of the per-underlying-interface structure is:
sizeof(rwlock_t) + sizeof(pppox_sock*) * PPPOE_HASH_SIZE.
Assuming a 64-bit pointer this will result in just over a 2KiB structure
for PPPOE_HASH_BITS=8, which will likely result in a 4KiB allocation,
which for us at least is acceptable.
Not sure what the minimum allocation size is, and thus if values of 1
and 2 truly make sense. Default results in historic sizing and
behaviour.

The XPCS expects clause 73 (copper backplane) autoneg to follow the
ethtool autoneg bit. It actually did that until the blamed
commit inaptly replaced state->an_enabled (coming from ethtool) with
phylink_autoneg_inband() (coming from the device tree or struct
phylink_config), as part of an unrelated phylink_pcs API conversion.
Russell King suggests that state->an_enabled from the original code was
just a proxy for the ethtool Autoneg bit, and that the correct way of
restoring the functionality is to check for this bit in the advertising

Feroceon CPUs have a non-standard implementation of VFP which reports
synchronous VFP exceptions using the async VFP flag. This requires a
workaround which is difficult to reconcile with other implementations,
making it tricky to support both versions in a single image.
Since this is a v5 CPU, it is not supported by armhf and so the
likelihood that anybody is using this with recent distros/kernels and
rely on the VFP at the same time is extremely low. So let's just disable
VFP support on these cores, so we can remove the workaround.
This will help future development to support v5 and v6 CPUs with a
single kernel image.

This happens because when we abort the transaction in the transaction
commit path we call invalidate_inode_pages2_range on our block group
cache inodes (if we have space cache v1) and any delalloc inodes we may
have. The plain invalidate_inode_pages2_range() call passes through
GFP_KERNEL, which makes sense in most cases, but not here. Wrap these
two invalidate callees with memalloc_nofs_save/memalloc_nofs_restore to
make sure we don't end up with the fs reclaim dependency under the
transaction dependency.

Currently we allow a block group not to be marked read-only for scrub.
But for RAID56 block groups if we require the block group to be
read-only, then we're allowed to use cached content from scrub stripe to
reduce unnecessary RAID56 reads.
So this patch would:
- Make btrfs_inc_block_group_ro() try harder
During my tests, for cases like btrfs/061 and btrfs/064, we can hit
ENOSPC from btrfs_inc_block_group_ro() calls during scrub.
The reason is if we only have one single data chunk, and trying to
scrub it, we won't have any space left for any newer data writes.
But this check should be done by the caller, especially for scrub
cases we only temporarily mark the chunk read-only.
And newer data writes would always try to allocate a new data chunk
when needed.
- Return error for scrub if we failed to mark a RAID56 chunk read-only

====================
ice: support dynamic interrupt allocation
Piotr Raczynski says:
This patchset reimplements MSIX interrupt allocation logic to allow dynamic
interrupt allocation after MSIX has been initially enabled. This allows
current and future features to allocate and free interrupts as needed and
will help to drastically decrease number of initially preallocated
interrupts (even down to the API hard limit of 1). Although this patchset
does not change behavior in terms of actual number of allocated interrupts
during probe, it will be subject to change.
First few patches prepares to introduce dynamic allocation by moving
interrupt allocation code to separate file and update allocation API used
in the driver to the currently preferred one.
Due to the current contract between ice and irdma driver which is directly
accessing msix entries allocated by ice driver, even after moving away from
older pci_enable_msix_range function, still keep msix_entries array for
irdma use.
Next patches refactors and removes redundant code from SRIOV related logic
as it also make it easier to move away from static allocation scheme.
Last patches actually enables dynamic allocation of MSIX interrupts. First,
introduce functions to allocate and free interrupts individually. This sets
ground for the rest of the changes even if that patch still allocates the
interrupts from the preallocated pool. Since this patch starts to keep
interrupt details in ice_q_vector structure we can get rid of functions
that calculates base vector number and register offset for the interrupt
as it is equal to the interrupt index. Only keep separate register offset
functions for the VF VSIs.
Next, replace homegrown interrupt tracker with much simpler xarray based
approach. As new API always allocate interrupts one by one, also track
interrupts in the same manner.
Lastly, extend the interrupt tracker to deal both with preallocated and
dynamically allocated vectors and use pci_msix_alloc_irq_at and
pci_msix_free_irq functions. Since not all architecture supports dynamic
allocation, check it before trying to allocate a new interrupt.
As previously mentioned, this patchset does not change number of initially
allocated interrupts during init phase but now it can and will likely be
changed.
Patch 1-3 -> move code around and use newer API
Patch 4-5 -> refactor and remove redundant SRIOV code
Patch 6 -> allocate every interrupt individually
Patch 7 -> replace homegrown interrupt tracker with xarray
Patch 8 -> allow dynamic interrupt allocation

In igb_hash_mc_addr() the expression:
"mc_addr[4] >> 8 - bit_shift", right shifting "mc_addr[4]"
shift by more than 7 bits always yields zero, so hash becomes not so different.
Add initialization with bit_shift = 1 and add a loop condition to ensure
bit_shift will be always in [1..8] range.

Due to the firmware behavior with HT fixed rate setting,
HT fixed rate MCS with NSS > 1 are treated as NSS = 1
HT rates in the firmware and enables the HT fixed rate of
NSS = 1.
This leads to HT fixed rate is always configured for NSS = 1
even though the user sets NSS = 2 or > 1 HT fixed MCS in the
set bitrate command.
Currently HT fixed MCS is sent via WMI peer assoc command.
Fix this issue, by sending the HT fixed rate MCS in WMI peer
fixed param instead of sending in peer assoc command.

When vdev start/stop happens, response from firmware is received with delay
and hence there is a timeout before VDEV can be up/down.
Also, with maximum peers connected and when vdev stop occurs, firmware
will take time to clean up all the peers and vap queues.
In such cases as well, vdev start/stop response is sent by firmware with delay.
Increase the vdev setup timeout as recommended by firmware team.

'qcom,msm8996-qmp-usb3-phy.yaml' defines bindings for several PHYs
which predate USB -> USB+DP migration. Since SM6115 and QCM2290
nodes for USB QMP phy are being added to dtsi files by followup patches,
move these bindings instead to the newer style
'qcom,sc8280xp-qmp-usb3-uni-phy.yaml' file.
Since no device trees use these bindings presently, so we have no ABI breakages
with this patch.

TSSI is transmitter signal strength indication, which is a close-loop
hardware circuit to feedback actual transmitting power as a reference for
next transmission.
When we setup channel to connect an AP, it does full calibration. When
switching bands or channels, it needs to reset hardware status to prevent
use wrong feedback of previous transmission.
To do TX power compensation reflecting current temperature, it loads tables
of compensation values into registers according to channel and band group.
