The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch

The change to call busy->div_ops->determine_rate() instead of
busy->div_ops->round_rate() was done by hand.

This driver implements both the determine_rate() and round_rate() clk
ops, and the round_rate() clk ops is deprecated. When both are defined,
clk_core_determine_round_nolock() from the clk core will only use the
determine_rate() clk ops, so let's remove the round_rate() clk ops since
it's unused.

Add doorbell support with the help of three new registers:
PCIE_ENDPOINT_TEST_DB_BAR, PCIE_ENDPOINT_TEST_DB_ADDR, and
PCIE_ENDPOINT_TEST_DB_DATA.
The testcase works by triggering the doorbell in Endpoint by writing the
value from PCI_ENDPOINT_TEST_DB_DATA register to the address provided by
PCI_ENDPOINT_TEST_DB_OFFSET register of the BAR indicated by the
PCIE_ENDPOINT_TEST_DB_BAR register and waiting for the completion status
from the Endpoint.

Add doorbell support by allocating a dedicated BAR using the
pci_epf_alloc_doorbell() API and mapping the Endpoint MSI controller
message data address to it. The data to be written in the message address
is stored in the 'pci_epf_test_reg::doorbell_data' register. Finally, the
RC can trigger doorbell in the Endpoint by writing the content of
'doorbell_data' register to the offset specified in 'doorbell_offset' of
the 'doorbell_bar' BAR.
Triggering of the doorbell is detected by pci_epf_test_doorbell_handler(),
which is bound to the doorbell IRQ. On successful completion,
STATUS_DOORBELL_SUCCESS status is set in the above mentioned handler.
To avoid breaking compatibility between host and endpoint, add two new
commands: COMMAND_ENABLE_DOORBELL and COMMAND_DISABLE_DOORBELL.
The doorbell is allocated when COMMAND_ENABLE_DOORBELL command is called
and destroyed when COMMAND_DISABLE_DOORBELL is called.
This doorbell feature only works when both RC and EP drivers support it.
If one of them doesn't support the feature, the testcase will fail.

Some MSI controllers can change address/data pair during the execution of
irq_chip::irq_set_affinity() callback. Since the current PCI Endpoint
framework cannot support mutable MSI controllers, call
irq_domain_is_msi_immutable() API to check if the controller is immutable
or not.
Also ensure that the MSI domain is a parent MSI domain so that it can
allocate address/data pairs.

All irq_domain functions now accept fwnode instead of of_node. But many
PCI controllers still extract dev to of_node and then of_node to fwnode.
Instead, clean this up and simply use the dev_fwnode() helper to extract
fwnode directly from dev. Internally, it still does dev => of_node =>
fwnode steps, but it's now hidden from the users.
In the case of altera, this also removes an unused 'node' variable that is
only used when CONFIG_OF is enabled:
drivers/pci/controller/pcie-altera.c: In function 'altera_pcie_init_irq_domain':
drivers/pci/controller/pcie-altera.c:855:29: error: unused variable 'node' [-Werror=unused-variable]

According to Documentation/PCI/endpoint/pci-endpoint-cfs.rst, the Endpoint
controller (EPC) should only start the link when userspace writes '1' to
the '/sys/kernel/config/pci_ep/controllers/<EPC>/start' attribute, which
ultimately results in calling imx_pcie_start_link() via
pci_epc_start_store().
To align with the documented behavior, do not start the link automatically
when adding the EP controller.

apps_reset corresponds to LTSSM_EN in i.MX7, i.MX8MQ, i.MX8MM and i.MX8MP
platforms. Since assertion/de-assertion of apps_reset is done in
imx_pcie_ltssm_enable() and imx_pcie_ltssm_disable(), remove it from
imx_pcie_assert_core_reset() and imx_pcie_deassert_core_reset().
This also fixes a failure in enumerating the PI7C9X2G608GP (hotplug) chip
reliably on i.MX8MM, as reported by Tim.
It should be noted that only i.MX7D, i.MX8MQ, i.MX8MM, and i.MX8MP
platforms have the apps_reset logic, so this change doesn't have any effect
on other platforms.

There is no need to store the err string in hw->err_str. Simplify it and
use common helper. hw->err_str is still used for other purpouse.
It should be marked that previously for unknown error the numeric value
was passed as a string. Now the "LIBIE_AQ_RC_UNKNOWN" is used for such
cases.
Add libie_aminq module in i40e Kconfig.

Add a new module for common handling of Admin Queue related logic.
Start by a helper for error to string conversion. This lives inside
libie/, but is a separate module what follows our logic of splitting
into topical modules, to avoid pulling in not needed stuff, and have
better organization in general.
Olek suggested how to better solve the error to string conversion.
It will be used in follow-up patches in ice, i40e and iavf.

Use libie_aq_desc instead of i40e_aq_desc. Do needed changes to allow
clean build.
Get version descriptor is a little less detailed on i40e. To not mess up
with shifting or union inside libie desc use get version descriptor from
i40e.
Move additional caps for i40e to libie.
Fix RCT in declaration that is using libie_aq_desc;
Use libie_aq_raw() wherever it can be used.
The libie aq error is extended, cover it in ice driver just to clean
build. In next patches the libie code for that will be used in each
of intel driver.

The descriptor structure is the same in ice, ixgbe and i40e. Move it to
common libie header to use it across different driver.
Leave device specific adminq commands in separate folders. This lead to
a change that need to be done in filling/getting descriptor:
- previous: struct specific_desc *cmd;
cmd = &desc.params.specific_desc;
- now: struct specific_desc *cmd;
cmd = libie_aq_raw(&desc);
Do this changes across the driver to allow clean build. The casting only
have to be done in case of specific descriptors, for generic one union
can still be used.
Changes beside code moving:
- change ICE_ prefix to LIBIE_ prefix (ice_ and libie_ too)
- remove shift variables not otherwise needed (in libie_aq_flags)
- fill/get descriptor data based on desc.params.raw whenever the
descriptor isn't defined in libie
- move defines from the libie_aq_sth structure outside
- add libie_aq_raw helper and use it instead of explicit casting

Pull networking fixes from Paolo Abeni:
"Including fixes from can and xfrm.
The TI regression notified last week is actually on our net-next tree,
it does not affect 6.16.
We are investigating a virtio regression which is quite hard to
reproduce - currently only our CI sporadically hits it. Hopefully it
should not be critical, and I'm not sure that an additional week would
be enough to solve it.
Current release - fix to a fix:
- sched: sch_qfq: avoid sleeping in atomic context in qfq_delete_class
Previous releases - regressions:
- xfrm:
- set transport header to fix UDP GRO handling
- delete x->tunnel as we delete x
- eth:
- mlx5: fix memory leak in cmd_exec()
- i40e: when removing VF MAC filters, avoid losing PF-set MAC
- gve: fix stuck TX queue for DQ queue format
Previous releases - always broken:
- can: fix NULL pointer deref of struct can_priv::do_set_mode
- eth:
- ice: fix a null pointer dereference in ice_copy_and_init_pkg()
- ism: fix concurrency management in ism_cmd()
- dpaa2: fix device reference count leak in MAC endpoint handling
- icssg-prueth: fix buffer allocation for ICSSG
Misc:
- selftests: mptcp: increase code coverage"
