fc44f3636a drm/bridge: lt8912b: clarify lvds output status
Add comments on the lt8912_write_lvds_config() config to document the
current settings and to make it clear that this is a hardcoded
configuration not relevant for the HDMI output (could be removed without
affecting the HDMI port).

No changes on the actual register writes.

051ad2788d drm/bridge: lt8912b: fix corrupted image output
Correct I2C address for the register list in lt8912_write_lvds_config(),
these registers are on the first I2C address (0x48), the current
function is just writing garbage to the wrong registers and this creates
multiple issues (artifacts and output completely corrupted) on some HDMI
displays.

Correct I2C address comes from Lontium documentation and it is the one
used on other out-of-tree LT8912B drivers [1].

d56f9ddf97 Merge branch 'sparx5-qos'
Daniel Machon says:

====================
net: Add QoS offload support for sparx5

This patch series adds support for offloading QoS features with the tc
command suite, to the sparx5 switch. The new offloadable QoS features
introduced in this patch series are:

  - tc-mqprio for mapping traffic class to hardware queue. Queues are by
    default mapped 1:1  in hardware, as such the mqprio qdisc is used as
    an attachment point for qdiscs tbf and ets.

    $ tc qdisc add dev eth0 root handle 1:0 mqprio

  - tc-tbf for setting up shaping on scheduler elements of the HSCH
    (Hierarchical Scheduler) block. Shaping on either port output or
    queue output is supported.

    Port shaper: $ tc qdisc add dev eth0 root handle 1:0 tbf rate \
    10000000 burst 8192 limit 1m

    Queue shaper: $ tc qdisc replace dev eth0 parent 1:5 handle 2:0 tbf \
    rate 10000000 burst 8192 limit 1m

  - tc-ets for setting up strict and or bandwidth-sharing bands on one
    through eight priority queues.

    Configure a mix of strict and bw-sharing bands:
    $ tc qdisc add dev eth0 handle 1: root ets bands 8 strict 5 \
    quanta 1000 1000 1000 priomap 7 6 5 4 3 2 1 0

Patch #1 Sets up the tc hook.
Patch #2 Adds support for offloading the tc-mqprio qdisc.
Patch #3 Adds support for offloading the tc-tbf qdisc.
Patch #4 Adds support for offloading the tc-ets qdisc.
Patch #5 Updates the maintainers of the sparx5 driver.

3c66563378 Revert "firmware: arm_scmi: Add clock management to the SCMI power domain"
This reverts commit a3b884cef8 ("firmware: arm_scmi: Add clock management
to the SCMI power domain").

Using the GENPD_FLAG_PM_CLK tells genpd to gate/ungate the consumer
device's clock(s) during runtime suspend/resume through the PM clock API.
More precisely, in genpd_runtime_resume() the clock(s) for the consumer
device would become ungated prior to the driver-level ->runtime_resume()
callbacks gets invoked.

This behaviour isn't a good fit for all platforms/drivers. For example, a
driver may need to make some preparations of its device in its
->runtime_resume() callback, like calling clk_set_rate() before the
clock(s) should be ungated. In these cases, it's easier to let the clock(s)
to be managed solely by the driver, rather than at the PM domain level.

For these reasons, let's drop the use GENPD_FLAG_PM_CLK for the SCMI PM
domain, as to enable it to be more easily adopted across ARM platforms.

fdffc091e6 erofs: support interlaced uncompressed data for compressed files
Currently, uncompressed data is all handled in the shifted way, which
means we have to shift the whole on-disk plain pcluster to get the
logical data.   However, since we are also using in-place I/O for
uncompressed data, data copy will be reduced a lot if pcluster is
recorded in the interlaced way as illustrated below:
 _______________________________________________________________
|               |    |               |_ tail part |_ head part _|
|<-   blk0    ->| .. |<-   blkn-2  ->|<-         blkn-1       ->|

The logical data then becomes:
 ________________________________________________________
|_ head part _|_  blk0  _| .. |_  blkn-2  _|_ tail part _|

In addition, non-4k plain pclusters are also survived by the
interlaced way, which can be used for non-4k lclusters as well.

However, it's almost impossible to de-duplicate uncompressed data
in the interlaced way, therefore shifted uncompressed data is still
useful.

97cfede0d1 Merge branch 'mlx5-macsec-extended-packet-number-and-replay-window-offload'
Saeed Mahameed says:

====================
mlx5 MACSec Extended packet number and replay window offload

This is a follow up series to the previously submitted mlx5 MACsec offload [1]
earlier this release cycle.

In this series we add the support for MACsec Extended packet number and
replay window offloads.

First patch is a simple modification (code movements) to the core macsec code
to allow exposing the EPN related user properties to the offloading
device driver.

The rest of the patches are mlx5 specific, we start off with fixing some
trivial issues with mlx5 MACsec code, and a simple refactoring to allow
additional functionality in mlx5 macsec to support EPN and window replay
offloads.
 A) Expose mkey creation functionality to MACsec
 B) Expose ASO object to MACsec, to allow advanced steering operations,
    ASO objects are used to modify MACsec steering objects in fastpath.

1) Support MACsec offload extended packet number (EPN)

    MACsec EPN splits the packet number (PN) into two 32-bits fields,
    epn_lsb (32 least significant bits (LSBs) of PN) and epn_msb (32
    most significant bits (MSBs) of PN).
    Epn_msb bits are managed by SW and for that HW is required to send
    an object change event of type EPN event notifying the SW to update
    the epn_msb in addition, once epn_msb is updated SW update HW with
    the new epn_msb value for HW to perform replay protection.
    To prevent HW from stopping while handling the event, SW manages
    another bit for HW called epn_overlap, HW uses the latter to get
    an indication regarding how to read the epn_msb value correctly
    while still receiving packets.
    Add epn event handling that updates the epn_overlap and epn_msb for
    every 2^31 packets according to the following logic:
    if epn_lsb crosses 2^31 (half sequence number wraparound) upon HW
    relevant event, SW updates the esn_overlap value to OLD (value = 1).
    When the epn_lsb crosses 2^32 (full sequence number wraparound)
    upon HW relevant event, SW updates the esn_overlap to NEW
    (value = 0) and increment the esn_msb.
    When using MACsec EPN a salt and short secure channel id (ssci)
    needs to be provided by the user, when offloading EPN need to pass
    this salt and ssci to the HW to be used in the initial vector (IV)
    calculations.

2) Support MACsec offload replay window

    Support setting replay window size for MACsec offload.
    Currently supported window size of 32, 64, 128 and 256
    bit. Other values will be returned as invalid parameter.
