Add validation for the "max-link-speed" DT property in three more
drivers, using the pcie_get_link_speed() helper.
- brcmstb: If the value is missing or invalid, fall back to no
limitation (pcie->gen = 0). Fix the previous incorrect logic.
- mediatek-gen3: If the value is missing or invalid, use the maximum
speed supported by the controller.
- rzg3s-host: If the value is missing or invalid, fall back to Gen2.
This ensures that all users of of_pci_get_max_link_speed() are ready
for the removal of the central range check.

Use the new pcie_get_link_speed() helper to validate the value read from

Replace direct indexing of pcie_link_speed[] with the new helper
pcie_get_link_speed() in all DesignWare core and glue drivers. This
ensures that out-of-range generation numbers do not cause out-of-bounds
accesses when the helper returns PCI_SPEED_UNKNOWN, and prepares for
the removal of the range check in of_pci_get_max_link_speed().
The actual validation of the "max-link-speed" DT property (e.g., fallback
to a safe default and warning) is added in subsequent patches for each
driver that reads the property.

The pcie_link_speed[] array is indexed by PCIe generation numbers
(1 = 2.5 GT/s, 2 = 5 GT/s, ...). Several drivers use it directly,
which can lead to out-of-bounds accesses if an invalid generation
number is used.
Introduce a helper function pcie_get_link_speed() that returns the
pci_bus_speed value for a given generation number, or PCI_SPEED_UNKNOWN if
the generation is out of range. This will allow us to safely handle
invalid values after the range check is removed from
of_pci_get_max_link_speed().

In preparation to restoring the ability of MSM8974 driver to work with
the modern kernels, switch the driver to the main icc-rpm set of helper
code.
As platform-specific workarounds, set the get_bw callback (returning 0)
to prevent initial setup from programming INT_MAX into the RPM (which
otherwise might hang the platform) and tell RPM programming code to
ignore -ENXIO errors from the firmware (until the QoS programming is
sorted out).

On MSM8974 programming some of the RPM resources results in the
"resource does not exist" messages from the firmware. This occurs even
with the downstream bus driver, which happily ignores the errors. My
assumption is that these resources existed in the earlier firmware
revisions but were later switched to be programmed differently (for the
later platforms corresponding nodes use qos.ap_owned, which prevents
those resources from being programmed.
In preparation for conversion of the MSM8974 driver (which doesn't have
QoS code yet) to the main icc-rpm set of helpers, let the driver declare
that those -ENXIO errors must be ignored (for now). Later, when the QoS
programming is sorted out (and more interconnects are added to the DT),
this quirk might be removed.

Qcom PCIe Root Ports advertise hotplug capability in hardware, but do not
support hotplug command completion. As a result, the hotplug commands
issued by the pciehp driver never gets completion notification, leading to
repeated timeout warnings and multi-second delays during boot and
suspend/resume.
Commit a54db86ddc ("PCI: qcom: Do not advertise hotplug capability for
IPs v2.7.0 and v1.9.0") mistakenly assumed that the Root Ports doesn't
support Hotplug due to timeouts and disabled the Hotplug functionality
altogether. But the Root Ports does support reporting Hotplug events like
DL_Up/Down events.
So to fix the command completion timeout issues, just set the No Command

whether the link has entered L2/L3 Ready state or not.
Hence, set IMX_PCIE_FLAG_SKIP_L23_READY flag for i.MX6SX SoC to skip the
L2/L3 Ready state polling and let the DWC core wait for 10ms after sending
the PME_Turn_Off message as per the PCIe spec r6.0, sec 5.3.3.2.1.

When a caller enqueues a work item using schedule_delayed_work() the used
wq is "system_wq" (per-cpu wq) while queue_delayed_work() uses
WORK_CPU_UNBOUND (used when no target CPU is specified). The same applies
to schedule_work() that is using system_wq and queue_work(), which again
makes use of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
Continue the effort to refactor workqueue APIs, which began with the
introduction of new workqueues and a new alloc_workqueue() flag in:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
and switch smp_call_on_cpu() to use system_percpu_wq because system_wq is
going away once the ongoing workqueue restructuring is done.

gic_irq_domain_translate() does not check if an interrupt number lies
within the valid range of the specified interrupt type. Add these checks,
and print a warning if the interrupt number is out of range.
This can help flagging incorrectly described Extended SPI and PPI
interrupts in DT.

Bard Liao <yung-chuan.liao@linux.intel.com> says:
The new rt722 + rt1320 configuration uses the DMIC on the rt1320.
This series adds support for such configurations, where the DMIC is
provided by the rt1320 instead of the rt722.
According to the Intel sof design, it will create the name prefix
appended with amp index for the amp codec only, such as:
rt1318-1, rt1318-2, etc...
But the rt1320 is a codec with amp and mic codec functions, it doesn't
have the amp index in its name prefix as above.
And then it will be hard to identify the codec if in multi-rt1320 case.
So we add a flag to force the amp index to be appended.

Use functional topologies to support RT722 topologies with/without
amplifiers,
e.g. sof-ptl-rt722.tplg, sof-ptl-rt722-rt1320.tplg...
If these entries are not removed, they will find the first same link of
sof-ptl-rt722.tplg.
