Pull SoC driver updates from Arnd Bergmann:
 "There are a few added drivers, but mostly the normal maintenance to
  drivers for firmware, memory controller and other soc specific
  hardware:

   - The NXP QuickEngine gets modern MSI support, which allows some
     cleanups to the GICv3 irqchip chip driver

   - A new SoC specific driver for the Renesas R-Car MFIS unit is added,
     encapsulating support for the on-chip mailbox and hwspinlock
     implementations that are not easily separated into individual
     drivers

   - The Qualcomm SoC drivers add support for additional SoC
     implementations, and flexibility around power management for the
     serial-engine driver as well as probing the LLCC driver using
     custom hardware descriptions inside of the device itself.

   - Added support for the Samsung thermal management unit

   - A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
     APIs and allow multiple PMC instances everywhere.

   - Updates to the TI SCI and KNAS drivers to improve suspend/resume
     support.

   - Minor driver changes for mediatek, xilinx, allwinner, aspeed,
     tegra, broadcom, amd, microchip and starfive specific drivers

   - Memory controller updates for Tegra and Renesas for additional SoC
     types and other improvements.

   - Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces, to
     update driver probing, object lifetimes and address minor bugs"

Implement the DSA .port_vlan_add and .port_vlan_del operations to enable
VLAN-aware bridge offloading on the NETC switch.

VLAN membership is maintained in the VLAN Filter Table (VFT). Adding the
first port to a VLAN creates a new VFT entry with hardware MAC learning
and flood-on-miss forwarding; subsequent ports update the existing
entry's membership bitmap. Removing the last port deletes the entry.

Egress tagging is handled through the Egress Treatment Table (ETT). Each
VLAN is allocated a group of ETT entries, one per available port. Ports
are assigned a sequential ett_offset during initialisation, used to
address each port's entry within the group. Untagged ports configure the
ETT to strip the outer VLAN tag; tagged ports pass frames through
unmodified. Each ETT group is optionally paired with an Egress Counter
Table (ECT) group for per-port frame counting, allocated on a best-effort
basis. When the egress rule of an ETT entry changes, the counter of the
corresponding ECT entry will be recounted to track the number of frames
that match the new egress rule.

A software shadow list serialised by vft_lock tracks active VLAN state
across both port membership and egress tagging. VID 0 is used for single
port mode and is ignored by both callbacks.

NTMP index tables require software to allocate and manage entry IDs.
Add two bitmap helper functions to facilitate this management:

ntmp_lookup_free_eid(): finds the first zero bit in the given bitmap,
sets it to mark the entry as in-use, and returns the corresponding entry
ID. Returns NTMP_NULL_ENTRY_ID if no free entry is available.

ntmp_clear_eid_bitmap(): clears the bit associated with the given entry
ID in the bitmap to mark the entry as free. It is a no-op if the entry
ID is NTMP_NULL_ENTRY_ID.

Both functions are exported for use by other modules, such as the NETC
switch driver which needs to manage group index bitmaps for the Egress
Treatment Table (ETT) and Egress Count Table (ECT).

The Egress Treatment Table (ETT) and Egress Count Table (ECT) are both
index tables whose entry IDs are allocated by software. Every num_ports
entries form a group, where each entry in the group corresponds to one
port. To facilitate group allocation and management, initialize the group
index bitmaps for both tables based on hardware capabilities reported by
ETTCAPR and ECTCAPR registers.

The bitmap size per table is calculated as the total number of hardware
entries divided by the number of available ports, which gives the number
of groups available for software allocation. A set bit in the bitmap
represents a group index that has been allocated.

These bitmaps will be used by subsequent patches that add VLAN support.

The egress count table is a static bounded index table, egress related
statistics are maintained in this table. The table is implemented as a
linear array of entries accessed using an index (0, 1, 2, ..., n) that
uniquely identifies an entry within the array. Egress Counter Entry ID
(EC_EID) is used as an index to an entry in this table. The EC_EID is
specified in the egress treatment table.

Egress count table entries are always present and enabled. The table
only supports access via entry ID, which is assigned by the software.
And it supports Update, Query and Query followed by Update operations.
Currently, only Update operation is supported.

Each entry in the egress treatment table contains the egress packet
processing actions to be applied to a grouping or scope of packets
exiting on a particular egress port of the switch. A scope of packets,
for example, could be the packets exiting a particular VLAN, matching
a particular 802.1Q bridge forwarding entry or belonging to a stream
identified at ingress. The egress treatment table is implemented as a
linear array of entries accessed using an index (0,1, 2, ..., n) that
uniquely identifies an entry within the array.

The egress treatment table only supports access vid entry ID, which is
assigned by the software. It supports Add, Update, Delete and Query
operations. Note that only Query operation is not supported yet.

Add two interfaces to manage entries in the VLAN filter table:

ntmp_vft_update_entry(): Update the configuration element data of the
specified VLAN filter entry based on the given VLAN ID. It uses the
exact key access method to locate the entry.

ntmp_vft_delete_entry(): Delete the VLAN filter entry corresponding to
the specified VLAN ID. It also uses the exact key access method to
identify the target entry.

In addition, introduce struct vft_req_qd to describe the request data
buffer format for Query and Delete actions of the VLAN filter table,
which contains a common request data header and a VLAN access key.

Add three interfaces to manage dynamic entries in the FDB table:

ntmp_fdbt_update_activity_element(): Update the activity element of all
dynamic FDB entries. For each entry, if its activity flag is not set,
which means no packet has matched this entry since the last update, the
activity counter is incremented. Otherwise, both the activity flag and
activity counter are reset. The activity counter is used to track how
long an FDB entry has been inactive, which is useful for implementing
an ageing mechanism.

ntmp_fdbt_delete_ageing_entries(): Delete all dynamic FDB entries whose
activity flag is not set and whose activity counter is greater than or
equal to the specified threshold. This is used to remove stale entries
that have been inactive for too long.

ntmp_fdbt_delete_port_dynamic_entries(): Delete all dynamic FDB entries
associated with the specified switch port. This is typically called when
a port goes down or is removed from a bridge.

Each user port of the NETC switch supports 802.3 basic and mandatory
managed objects statistic counters and IETF Management Information
Database (MIB) package (RFC2665) and Remote Network Monitoring (RMON)
counters. And all of these counters are 64-bit registers. In addition,
some user ports support preemption, so these ports have two MACs, MAC
0 is the express MAC (eMAC), MAC 1 is the preemptible MAC (pMAC). So
for ports that support preemption, the statistics are the sum of the
pMAC and eMAC statistics.

Note that the current switch driver does not support preemption, all
frames are sent and received via the eMAC by default. The statistics
read from the pMAC should be zero.

The ingress port filter table (IPFT )contains a set of filters each
capable of classifying incoming traffic using a mix of L2, L3, and L4
parsed and arbitrary field data. As a result of a filter match, several
actions can be specified such as on whether to deny or allow a frame,
overriding internal QoS attributes associated with the frame and setting
parameters for the subsequent frame processing functions, such as stream
identification, policing, ingress mirroring. Each entry corresponds to a
filter. The ingress port filter entries are added using a precedence
value. If a frame matches multiple entries, the entry with the higher
precedence is used. Currently, this patch only adds "Add" and "Delete"
operations to the ingress port filter table. These two interfaces will
be used by both ENETC driver and NETC switch driver.
