At present IDPF supports only 0x1452 and 0x145C as PF and VF device IDs
on our current generation hardware. Future hardware exposes a new set of
device IDs for each generation. To avoid adding a new device ID for each
generation and to make the driver forward and backward compatible,
make use of the IDPF PCI programming interface to load the driver.
Write and read the VF_ARQBAL mailbox register to find if the current
device is a PF or a VF.
PCI SIG allocated a new programming interface for the IDPF compliant
ethernet network controller devices. It can be found at:
https://members.pcisig.com/wg/PCI-SIG/document/20113
with the document titled as 'PCI Code and ID Assignment Revision 1.16'
or any latest revisions.
Tested this patch by doing a simple driver load/unload on Intel IPU E2000
hardware which supports 0x1452 and 0x145C device IDs and new hardware
which supports the IDPF PCI programming interface.

CTC adapter throws CTC_EVENT_UC_RCRESET (Unit check remote reset event)
during initial handshake, if the peer is not ready yet. This causes the
ctcm driver to re-attempt the handshake.
As it is normal for the event to occur during initialization, use info
instead of warn level in kernel log and NOTICE instead of ERROR level
in s390 debug feature. Also reword the log message for clarity.

If mfd_add_devices() fails, there is no need to call mfd_remove_devices().
The needed clean-up is already done in the error handling path of
mfd_add_devices().
So, remove the unneeded (and harmless) call.

MAX77620 is most likely always a single device on the board, however
nothing stops board designers to have two of them, thus same device
driver could probe twice. Or user could manually try to probing second
time.
Device driver is not ready for that case, because it allocates
statically 'struct regmap_irq_chip' as non-const and stores during
probe in 'irq_drv_data' member a pointer to per-probe state
container ('struct max77620_chip'). devm_regmap_add_irq_chip() does not
make a copy of 'struct regmap_irq_chip' but store the pointer.
Second probe - either successful or failure - would overwrite the
'irq_drv_data' from previous device probe, so interrupts would be
executed in a wrong context.

When da9055_device_init() fails after regmap_add_irq_chip()
succeeds but mfd_add_devices() fails, the error handling path
only calls mfd_remove_devices() but forgets to call
regmap_del_irq_chip(). This results in a resource leak.
Fix this by adding regmap_del_irq_chip() to the error path so
that resources are released properly.

When the global kernel command line parameter
memory_hotplug.memmap_on_memory is set to false, per-memory-block
memmap_on_memory setting can still be set to true. However, when
configuring memory block, add_memory_resource() would configure it
without memmap_on_memory.
i.e.
Even if the MHP_MEMMAP_ON_MEMORY flag is set,
mhp_supports_memmap_on_memory() returns false unless the kernel command
line parameter "memory_hotplug.memmap_on_memory" is enabled. When both
the flag and the cmdline parameter are set, the memory block can be
configured with or without memmap_on_memory support.
To ensure consistent behavior, permit configuring per-memory-block
memmap_on_memory only when the memory_hotplug.memmap_on_memory kernel
command line parameter is enabled.
This is similar to commit 73954d379efd ("dax: add a sysfs knob to
control memmap_on_memory behavior")

The DRM_GEM_SHMEM_HELPER helper requires MMU enabled because it uses
vmf_insert_pfn() in its mmap implementation. On NOMMU configurations
(e.g. some RISC-V randconfig builds), this symbol is unavailable and
selecting DRM_GEM_SHMEM_HELPER causes a modpost undefined reference:
ERROR: modpost: "vmf_insert_pfn" [drivers/gpu/drm/drm_shmem_helper.ko] undefined!
Normally, Kconfig prevents this helper from being selected when
CONFIG_MMU=n. However, in some randconfig builds (such as those used by
0day CI), select statements can override unmet dependencies, triggering
the issue.
Add an explicit dependency on MMU to DRM_PIXPAPER to prevent this.

Currently, the NUM_CONTROLLERS macro is used to limit the amount of memory
controllers (UMCs) available per node. The number of UMCs available per node,
however, is already cached by the max_mcs variable of struct amd64_pvt.
Allocate the relevant data structures dynamically using the variable instead
of static allocation through the macro.
The max_mcs variable is used for legacy systems too. These systems have a max
of 2 controllers. Since the default value of max_mcs, set in per_family_init(),
is 2, these legacy systems are also covered.

On hardware architectures where a single CAMNOC module is split into
two, one for each of the real time (RT) and non real time (NRT) modules
within camera sub system, processing VFE output over the AXI bus
requires enabling and setting the appropriate clock rate for the RT
CAMNOC. This change lays the groundwork for supporting such
configurations.

Replace the hardcoded buffer count value with a macro to enable
operating on these buffers elsewhere in the CAMSS driver based on this
count. Some of the hardware architectures require deferring the AUP and
REG update until after the CSID configuration and this macro is expected
to be useful in such scenarios.

The static TPDM function as a dummy source, however, it is essential
to enable the port connected to the TPDA and configure the element size.
Without this, the TPDA cannot correctly receive trace data from the
static TPDM. Since the static TPDM does not require MMIO mapping to
access its registers, a clock controller is not mandatory for its
operation.

Currently, the ctl_name string is statically assigned based on the family and
model of the SOC when the amd64_edac module is loaded.
The same, however, is not exactly needed as the string can be generated and
assigned at runtime through scnprintf().
Remove all static assignments and generate the string at runtime. Also,
cleanup the switch cases which became defunct and consolidate identical cases.

Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>:
This series adds support for three new MediaTek PMICs: MT6316, MT6363
and MT6373 and their variants - used in board designs featuring the
MediaTek MT8196 Chromebook SoC, or the MT6991 Dimensity 9400 Smartphone
SoC.
In particular, MT6316 is a regulator, but the MT6363 and MT6373 PMICs
are multi-function devices, as they have and expose multiple sub-devices;
moreover, some of those also contain an interrupt controller, managing
internal IPs interrupts: for those, a chained interrupt handler is
registered, which parent is the SPMI controller itself.
This series adds support for all of the MT6316 regulator variants and
for MT6363, MT6373 SPMI PMICs and their interrupt controller.

Merge series from Srinivas Kandagatla <srinivas.kandagatla@oss.qualcomm.com>:
This patchset has 4 fixes and some enhancements to the Elite DSP driver
support.
Fixes includes
- setting correct flags for expected behaviour of appl_ptr
- fix closing of copp instances
- fix buffer alignment.
- fix state checks before closing asm stream
Enhancements include:
- adding q6asm_get_hw_pointer and ack callback support
- simplify code via __free(kfree) mechanism.
- use spinlock guards
- few cleanups discovered during doing above 2.
There is another set of updates comming soon, which will add support
for early memory mapping and few more modules support in audioreach.

Add sanity check in iris_vb2_stop_streaming. If inst->state is
already IRIS_INST_ERROR, we should skip the stream_off operation
because it would still send packets to the firmware.
In iris_kill_session, inst->state is set to IRIS_INST_ERROR and
session_close is executed, which will kfree(inst_hfi_gen2->packet).
If stop_streaming is called afterward, it will cause a crash.

Improve the condition used to determine when input internal buffers need
to be reconfigured during streamon on the capture port. Previously, the
check relied on the INPUT_PAUSE sub-state, which was also being set
during seek operations. This led to input buffers being queued multiple
times to the firmware, causing session errors due to duplicate buffer
submissions.
This change introduces a more accurate check using the FIRST_IPSC and
DRC sub-states to ensure that input buffer reconfiguration is triggered
only during resolution change scenarios, such as streamoff/on on the
capture port. This avoids duplicate buffer queuing during seek
operations.
