Initialize the control handler by reading the platform specific firmware
capabilities. Capabilities are features, which are supported by a
specific platform (SOC). Each capability is defined with a min, max,
range and default value and a corresponding HFI. Implement s_ctrl and
g_volatile_ctrl ctrl ops.

The Host firmware interface (HFI) is a well defined set of interfaces
for the communication between the host driver and the firmware. The
commands and responses are exchanged in form of packets. One or multiple
packets are grouped under the packet header. Each packet has a packet
type which describes the specific HFI and the payload, which holds the
corresponding value for that HFI.

Introduce a core state management for iris driver with the necessary
queues needed for the host firmware communication.
There are 3 types of queues:
Command queue - driver to write any command to firmware.
Message queue - firmware to send any response to the driver.
Debug queue - for the firmware to write debug messages.
Initialize and configure the shared queues during probe.
Different states for core:
IRIS_CORE_DEINIT - default state.
IRIS_CORE_INIT - core state with core initialized. FW loaded and HW
brought out of reset, shared queues established
between host driver and firmware.
IRIS_CORE_ERROR - error state.

control regs
New versions of the CSIPHY locate the control registers at offset 0x1000
not offset 0x800.
Provide a variable to base an offset from for the purposes of redirecting

The existing setup bases from 0x800, the new from 0x1000 with some of the

and up the same as before.

Adding a new CSIPHY init sequence using downstream as a reference prompted
me to look at why we are splitting up the init sequence into chunks.
Right now we declare CSI PHY init sequences as an array of five equally
sized writes with a hard-coded control loop to iterate through each of the
five indexes. One bug in this model is that if you don't have an even
number of writes, you can't init the PHY as you wish.
In downstream the original code has something of the character
phy_init_seq[MAX_LANES][MAX_PARAMS] which in upstream we have translated
into phy_init_seq[5][SOME_NUMBER_OF_EQUAL_WRITES];
What the code does is take a pointer to the first index of the
r = &phy_init_seq[0][0]; and then literally does write(r, value); r++;
The controlling loop that hard-codes '5' in-lieu of MAX_LANES does no
special sleep, fabric-coherence sync or even a printk() to justify its
existence. Our compilers are optimising all of this away anyway so lets
drop.
Reduce the array declaration down to one flat aggregate init and let the
code just step through. As a happy side-effect we can then also handle
odd-number writes as the number of elements in the init sequence will no
longer have to be evenly divisible.

This reverts commit 3dd075fe8ebbc6fcbf998f81a75b8c4b159a6195.
Tomasz has reported that his device, Generalplus Technology Inc. 808 Camera,
with ID 1b3f:2002, stopped being detected:
$ ls -l /dev/video*
zsh: no matches found: /dev/video*
[ 7.230599] usb 3-2: Found multiple Units with ID 5
This particular device is non-compliant, having both the Output Terminal
and Processing Unit with ID 5. uvc_scan_fallback, though, is able to build
a chain. However, when media elements are added and uvc_mc_create_links
call uvc_entity_by_id, it will get the incorrect entity,
media_create_pad_link will WARN, and it will fail to register the entities.
In order to reinstate support for such devices in a timely fashion,
reverting the fix for these warnings is appropriate. A proper fix that
considers the existence of such non-compliant devices will be submitted in
a later development cycle.

When block drivers or the core block code perform allocations with a
frozen queue, this could try to recurse into the block device to
reclaim memory and deadlock. Thus all allocations done by a process
that froze a queue need to be done without __GFP_IO and __GFP_FS.
Instead of tying to track all of them down, force a noio scope as
part of freezing the queue.
Note that nvme is a bit of a mess here due to the non-owner freezes,
and they will be addressed separately.

Pull networking fixes from Jakub Kicinski:
"Including fixes from IPSec, netfilter and Bluetooth.
Nothing really stands out, but as usual there's a slight concentration
of fixes for issues added in the last two weeks before the merge
window, and driver bugs from 6.13 which tend to get discovered upon
wider distribution.
Current release - regressions:
- net: revert RTNL changes in unregister_netdevice_many_notify()
- Bluetooth: fix possible infinite recursion of btusb_reset
- eth: adjust locking in some old drivers which protect their state
with spinlocks to avoid sleeping in atomic; core protects netdev
state with a mutex now
Previous releases - regressions:
- eth:
- mlx5e: make sure we pass node ID, not CPU ID to kvzalloc_node()
- bgmac: reduce max frame size to support just 1500 bytes; the
jumbo frame support would previously cause OOB writes, but now
fails outright
- mptcp: blackhole only if 1st SYN retrans w/o MPC is accepted, avoid
false detection of MPTCP blackholing
Previous releases - always broken:
- mptcp: handle fastopen disconnect correctly
- xfrm:
- make sure skb->sk is a full sock before accessing its fields
- fix taking a lock with preempt disabled for RT kernels
- usb: ipheth: improve safety of packet metadata parsing; prevent
potential OOB accesses
- eth: renesas: fix missing rtnl lock in suspend/resume path"

Pull more s390 updates from Alexander Gordeev:
- The rework that uncoupled physical and virtual address spaces
inadvertently prevented KASAN shadow mappings from using large pages.
Restore large page mappings for KASAN shadows
- Add decompressor routine physmem_alloc() that may fail, unlike
physmem_alloc_or_die(). This allows callers to implement fallback
paths
- Allow falling back from large pages to smaller pages (1MB or 4KB) if
the allocation of 2GB pages in the decompressor can not be fulfilled
- Add to the decompressor boot print support of "%%" format string,
width and padding hadnling, length modifiers and decimal conversion
specifiers
- Add to the decompressor message severity levels similar to kernel
ones. Support command-line options that control console output
verbosity
- Replaces boot_printk() calls with appropriate loglevel- specific
helpers such as boot_emerg(), boot_warn(), and boot_debug().
- Collect all boot messages into a ring buffer independent of the
current log level. This is particularly useful for early crash
analysis
- If 'earlyprintk' command line parameter is not specified, store
decompressor boot messages in a ring buffer to be printed later by
the kernel, once the console driver is registered
- Add 'bootdebug' command line parameter to enable printing of
decompressor debug messages when needed. That parameters allows
message suppressing and filtering
- Dump boot messages on a decompressor crash, but only if 'bootdebug'
command line parameter is enabled
- When CONFIG_PRINTK_TIME is enabled, add timestamps to boot messages
in the same format as regular printk()
- Dump physical memory tracking information on boot: online ranges,
reserved areas and vmem allocations
- Dump virtual memory layout and randomization details
- Improve decompression error reporting and dump the message ring
buffer in case the boot failed and system halted
- Add an exception handler which handles exceptions when FPU control
register is attempted to be set to an invalid value. Remove '.fixup'
section as result of this change
- Use 'A', 'O', and 'R' inline assembly format flags, which allows
recent Clang compilers to generate better FPU code
- Rework uaccess code so it reads better and generates more efficient
code
- Cleanup futex inline assembly code
- Disable KMSAN instrumention for futex inline assemblies, which
contain dereferenced user pointers. Otherwise, shadows for the user
pointers would be accessed
- PFs which are not initially configured but in standby create only a
single-function PCI domain. If they are configured later on, sibling
PFs and their child VFs will not be added to their PCI domain
breaking SR-IOV expectations.
Fix that by allowing initially configured but in standby PFs create
multi-function PCI domains
- Add '-std=gnu11' to decompressor and purgatory CFLAGS to avoid
compile errors caused by kernel's own definitions of 'bool', 'false',
and 'true' conflicting with the C23 reserved keywords
- Fix sclp subsystem failure when a sclp console is not present
- Fix misuse of non-NULL terminated strings in vmlogrdr driver
