Any registered clk_core structure can have a NULL pointer in its dev
field. While never actually documented, this is evidenced by the wide
usage of clk_register and clk_hw_register with a NULL device pointer,
and the fact that the core of_clk_hw_register() function also passes a
NULL device pointer.
A call to clk_hw_get_clk() on a clk_hw struct whose clk_core is in that
case will result in a NULL pointer derefence when it calls dev_name() on
that NULL device pointer.
Add a test for this case and use NULL as the dev_id if the device
pointer is NULL.

The modem remoteproc on older Qualcomm SoCs (e.g. MSM8916 and MSM8974)
implements the BAM-DMUX protocol to allow access to the network data
channels of the modem. The hardware/firmware resources required to
implement the BAM-DMUX driver are described in an extra node in the
device tree (with the compatible "qcom,bam-dmux").
This node logically belongs below the modem remoteproc, so that both
control interfaces (rpmsg_wwan_ctrl) and network interfaces (bam_dmux)
have a common parent.
Unlike other child devices of the modem remoteproc, the bam-dmux device
currently does not follow the state of the remoteproc (i.e. it is not
added/removed when the remoteproc is started/stopped). However, this is
an implementation detail of the bam_dmux driver in Linux that might
change in the future.
To be flexible for future changes, create a standard platform device
specifically only for "qcom,bam-dmux", rather than populating all child
nodes. This is also more consistent with the way the other child nodes
are handled in the driver.
Note: of_platform_device_create() and of_node_put() have NULL-checks
internally, so there is no need to check if the "qcom,bam-dmux" node
actually exists in the device tree.

Block Aperture Window support was an attempt to layer an error model
over PMEM for platforms that did not support machine-check-recovery.
However, it was abandoned before it ever shipped, and only ever existed
in the ACPI specification. Meanwhile Linux has carried a large pile of
dead code for non-shipping infrastructure. For years it has been off to
the side out of the way, but now CXL and recent directions with DAX
support have the potential to collide with this code.
In preparation for adding discontiguous namespace support, a
pre-requisite for the nvdimm subsystem to replace device-mapper for
striping + concatenation use cases, delete BLK aperture support.
On the obscure chance that some hardware vendor shipped support for this
mode, note that the driver will still keep BLK space reserved in the
label area. So an end user in this case would still have the opportunity
to report the regression to get BLK-mode support restored without
risking the data they have on that device.

Add support to the K3 DSP remoteproc driver to configure all the C66x
and C71x cores on J721E SoCs to be either in IPC-only mode or the
traditional remoteproc mode. The IPC-only mode expects that the remote
processors are already booted by the bootloader, and only perform the
minimum steps required to initialize and deinitialize the virtio IPC
transports. The remoteproc mode allows the kernel remoteproc driver to
do the regular load and boot and other device management operations for
a DSP.
The IPC-only mode for a DSP is detected and configured at driver probe
time by querying the System Firmware for the DSP power and reset state
and/or status and making sure that the DSP is indeed started by the
bootloaders, otherwise the device is configured for remoteproc mode.
Support for IPC-only mode is achieved through .attach(), .detach() and
.get_loaded_rsc_table() callback ops and zeroing out the regular rproc
ops .prepare(), .unprepare(), .start() and .stop(). The resource table
follows a design-by-contract approach and is expected to be at the base
of the DDR firmware region reserved for each remoteproc, it is mostly
expected to contain only the virtio device and trace resource entries.
NOTE:
The driver cannot configure a DSP core for remoteproc mode by any
means without rebooting the kernel if that DSP core has been started
by a bootloader. This is the current desired behavior and can be
enhanced in the future if the feature is needed.

The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.

Qualcomm SoCs based on the RPM architecture have a MSM Power Manager (MPM)
in always-on domain. In addition to managing resources during sleep, the
hardware also has an interrupt controller that monitors the interrupts
when the system is asleep, wakes up the APSS when one of these interrupts
occur and replays it to GIC after it becomes operational.
It adds an irqchip driver for this interrupt controller, and here are
some notes about it.
- For given SoC, a fixed number of MPM pins are supported, e.g. 96 pins
on QCM2290. Each of these MPM pins can be either a MPM_GIC pin or
a MPM_GPIO pin. The mapping between MPM_GIC pin and GIC interrupt
is defined by SoC, as well as the mapping between MPM_GPIO pin and
GPIO number. The former mapping is retrieved from device tree, while
the latter is defined in TLMM pinctrl driver.
- The power domain (PD) .power_off hook is used to notify RPM that APSS
is about to power collapse. This requires MPM PD be the parent PD of
CPU cluster.
- When SoC gets awake from sleep mode, the driver will receive an
interrupt from RPM, so that it can replay interrupt for particular
polarity.

The rproc_da_to_va() API is an exported function, so move its
declaration from the remoteproc local remoteproc_internal.h
to the public remoteproc.h file.
This will allow drivers outside of the remoteproc folder to be
able to use this API.

qcom_smd's only child, smd-rpm uses arch_initcall and both have to be up
before almost anything else to ensure the MSM SoCs will work fine and
nothing will have to resort to probe defering, as this is the main pillar
of all things DVFS on these machines. Promote it to arch_initcall to avoid
such issues.

Add support for creating filters for GTP-U and GTP-C in switchdev mode. Add
support for parsing GTP-specific options (QFI and PDU type) and TEID.
By default, a filter for GTP-U will be added. To add a filter for GTP-C,
specify enc_dst_port = 2123, e.g.:
tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \
enc_dst_port 2123 action mirred egress redirect dev $VF1_PR
Note: GTP-U with outer IPv6 offload is not supported yet.
Note: GTP-U with no payload offload is not supported yet.

Checking only protocol ids while searching for correct FVs can lead to a
situation, when incorrect FV will be added to the list. Incorrect means
that FV has correct protocol id but incorrect offset.
Call ice_get_sw_fv_list with ice_prot_lkup_ext struct which contains all
protocol ids with offsets.
With this modification allocating and collecting protocol ids list is
not longer needed.

Adding GTP device through ip link creates the situation where
GTP instance is not able to send GTP echo requests.
Echo requests are used to check if GTP peer is still alive.
With this patch, gtp_genl_ops are extended by new cmd (GTP_CMD_ECHOREQ)
which allows to send echo request in the given version of GTP
protocol (v0 or v1), from the given ms address to he given
peer. TID is not inclued because in all path management
messages it should be equal to 0.
When GTP echo response is detected, multicast message is
send to everyone in the gtp_genl_family. Message contains
GTP version, ms address and peer address.

Adding GTP device through ip link creates the situation where
there is no userspace daemon which would handle GTP messages
(Echo Request for example). GTP-U instance which would not respond
to echo requests would violate GTP specification.
When GTP packet arrives with GTP_ECHO_REQ message type,
GTP_ECHO_RSP is send to the sender. GTP_ECHO_RSP message
should contain information element with GTPIE_RECOVERY tag and
restart counter value. For GTPv1 restart counter is not used
and should be equal to 0, for GTPv0 restart counter contains
information provided from userspace(IFLA_GTP_RESTART_COUNT).

Currently, when the user wants to create GTP device, he has to
provide file handles to the sockets created in userspace (IFLA_GTP_FD0,
IFLA_GTP_FD1). This behaviour is not ideal, considering the option of
adding support for GTP device creation through ip link. Ip link
application is not a good place to create such sockets.
This patch allows to create GTP device without providing
IFLA_GTP_FD0 and IFLA_GTP_FD1 arguments. If the user sets
IFLA_GTP_CREATE_SOCKETS attribute, then GTP module takes care
of creating UDP sockets by itself. Sockets are created with the
commonly known UDP ports used for GTP protocol (GTP0_PORT and
GTP1U_PORT). In this case we don't have to provide encap_destroy
because no extra deinitialization is needed, everything is covered
by udp_tunnel_sock_release.
Note: GTP instance created with only this change applied, does
not handle GTP Echo Requests. This is implemented in the following
patch.
