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
Completed Support (NCCS) bit and enable Hotplug in Slot Capability field
back.

Merge fixes related to system sleep for 7.0-rc6:
- Prevent pm_restore_gfp_mask() from triggering a WARN_ON() in some
code paths in which it is legitimately called without invoking
pm_restrict_gfp_mask() previously (Youngjun Park)
- Update snapshot_write_finalize() to take trailing zero pages into
account properly which prevents user space restore from failing
subsequently in some cases (Alberto Garcia)
* pm-sleep:
PM: sleep: Drop spurious WARN_ON() from pm_restore_gfp_mask()
PM: hibernate: Drain trailing zero pages on userspace restore
Avoid manual size calculations and use the proper helper.

Extend the DesignWare PCIe controller's debugfs statistical counter
interface with event definitions from groups 5 through 7 as documented
in the DWC PCIe Databook (version 6.30a, section 3.8.2.3, Tables 3-59,
3-60, 3-61). These counters provide visibility into Layer1 non-error
events (link state transitions,ASPM, L1 substates), Layer2 DLLP
exchanges, and Layer3 TLP transactions.
The counters are exposed under the debugfs statistical counter directory,
allowing users to monitor link behavior and diagnose PCIe protocol issues
more effectively.

The imx_pcie_assert_core_reset() and imx_pcie_deassert_core_reset()
functions are primarily intended to reset the RC controller itself, not
the remote PCIe endpoint devices. However, the PERST# GPIO control was
previously embedded within these functions, which conflates two distinct
reset operations.
Move the PERST# GPIO handling into a dedicated function
imx_pcie_assert_perst(). This makes the code more maintainable and
prepares for parsing the reset-gpios property according to the new
Root Port DT binding in subsequent patches.

On i.MX6SX, the LTSSM registers become inaccessible after the
PME_Turn_Off message is sent to the link. So there is no way to verify
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.

But the rt1320 is a codec with amp and mic codec functions, it doesn't

And then it will be hard to identify the codec if in multi-rt1320 case.

The RZ/G3L SoC has 16 external interrupts, of which 8 are shared with TINT
(GPIO interrupts), whereas RZ/G2L has only 8 external interrupts with no
sharing. The shared interrupt line selection between external interrupt and
GPIO interrupt is based on the INTTSEL register. Add shared_irq_cnt
variable to struct rzg2l_hw_info handle these differences.
Add used_irqs bitmap to struct rzg2l_irqc_priv to track allocation state.
In the alloc callback, use test_and_set_bit() to enforce mutual exclusion
and configure the INTTSEL register to route to either the external
interrupt or TINT. In the free callback, use test_and_clear_bit() to

The IRQC block on the RZ/G3L SoC is almost identical to the one found on
the RZ/G2L SoC, with the following differences:
- The number of GPIO interrupts for TINT selection is 113 instead of 123.
- The pin index and TINT selection index are not in the 1:1 map.
- The number of external interrupts are 16 instead of 8, out of these
8 external interrupts are shared with TINT.
Add support for the RZ/G3L driver by filling the rzg2l_hw_info table and
adding LUT for mapping between pin index and TINT selection index.

The total number of external interrupts in RZ/G2L and RZ/G3L SoC are
different. The RZ/G3L has 16 external interrupts whereas RZ/G2L has only 8
external interrupts. Add irq_count variable in struct rzg2l_hw_info to
handle these differences and drop the macro IRQC_IRQ_COUNT.

rzfive_irqc_mask() and rzfive_irqc_unmask() use hw_irq range checks to
dispatch between IRQ and TINT masking operations. Split each into two
dedicated handlers — rzfive_irqc_irq_mask(), rzfive_irqc_tint_mask(),
rzfive_irqc_irq_unmask(), and rzfive_irqc_tint_unmask() — each operating
unconditionally on its respective interrupt type, removing the runtime
conditionals.
Assign the IRQ-specific handlers to rzfive_irqc_irq_chip and the
TINT-specific handlers to rzfive_irqc_tint_chip, consistent with the
separation applied to the EOI, set_type, and enable/disable callbacks in
previous patches.
While at it, simplify rzfive_irqc_{irq,tint}_{mask,unmask}() by replacing
raw_spin_lock locking/unlocking with scoped_guard().

rzg2l_irqc_irq_disable() and rzg2l_irqc_irq_enable() are used by both the
IRQ and TINT chips, but only perform TINT-specific work via
rzg2l_tint_irq_endisable(), guarded by a hw_irq range check.
Since the IRQ chip does not require this extra enable/disable handling,
replace its callbacks with the generic irq_chip_disable_parent() and
irq_chip_enable_parent() directly.
While at it, simplify rzfive_irqc_irq_enable() by replacing raw_spin_lock

The driver uses a single irq_chip instance shared across all interrupt
types, relying on dispatcher callbacks to differentiate between IRQ and
TINT regions at runtime.
Replace the per-SoC irq_chip and its dispatcher callbacks with dedicated
irq_chip instances for each interrupt region: IRQ and TINT. Subsequent
patches will add per-region callbacks for IRQ and TINT from the common
code.

The check `hwirq < IRQC_TINT_START` in rzg2l_irqc_alloc() is unnecessary as
the condition is already guaranteed to be false at that point in the code.
The outer `if (hwirq > IRQC_IRQ_COUNT)` block ensures that hwirq is always
above IRQC_IRQ_COUNT before reaching this check, and since IRQC_TINT_START
<= IRQC_IRQ_COUNT, the guard can never trigger.
Remove the dead code to simplify the allocation path.
