Merely printing the error log without the actual EPF name will not give
much clue to the users about the failure. Hence, print the EPF name also.

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.

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.

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
release the shared interrupt line and reset the INTTSEL. Also add INTTSEL
register save/restore support to the suspend/resume path.

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.

TINT handlers
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().

interrupts and rzfive_tint_endisable() for TINT interrupts, each operating

TINT-specific handlers
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
locking/unlocking with guard() and update the variable types of offset,

types, relying on dispatcher callbacks to differentiate between IRQ and
TINT regions at runtime.

rzg2l_irqc_alloc()
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.

A lot of code can be shared between the existing ACPI init flow with the
upcoming OF init flow.
Extract it into a dedicated function.
The re-ordering of parent interrupt allocation requires the architecture
code to reserve legacy interrupts from the dynamic allocation by overriding
arch_dynirq_lower_bound(), otherwise the parent of LPC irqchip will be
allocated in the intended static range of LPC interrupts, which leads to
allocation failure of LPC interrupts.

Michal corrects call to alloc_etherdev_mqs() to provide maximum number
of queues supported rather than currently allocated number of queues.
Petr Oros fixes issues related to some ethtool operations in switchdev
mode.
For iavf:
Kohei Enju corrects number of reported queues for ethtool statistics to
absolute max as using current number could race and cause out-of-bounds
issues.
For idpf:
Josh NULLs cdev_info pointer after freeing to prevent possible subsequent
improper access. He also defers setting of refillqs value until after
allocation to prevent possible NULL pointer dereference.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
idpf: only assign num refillqs if allocation was successful
idpf: clear stale cdev_info ptr
iavf: fix out-of-bounds writes in iavf_get_ethtool_stats()
ice: use ice_update_eth_stats() for representor stats
ice: fix inverted ready check for VF representors
ice: set max queues in alloc_etherdev_mqs()

Set the default number of queues per vPort to MANA_DEF_NUM_QUEUES (16),
as 16 queues can achieve optimal throughput for typical workloads. The
actual number of queues may be lower if it exceeds the hardware reported
limit. Users can increase the number of queues up to max_queues via
ethtool if needed.

The i.MX93 uses a newer version of the DW CSI-2 controller with a changed
register layout and an integrated Image Pixel Interface (IPI), which
converts the received CSI-2 packets from byte to pixel format and produces
a pixel data bus containing vertical and horizontal synchronization
information.
The reset flow also differs, so add the .assert_reset(), .deassert_reset(),
and .idi_enable() callbacks to support it.

Use enum dw_mipi_csi2rx_regs_index together with a u32 array to describe
register offsets. This allows supporting new IP versions with different
register layouts in a structured way.
Add rk3568_regs matching the previous macro definitions and pass it as
driver data during probe.
No functional change intended.

devm_clk_bulk_get_all() returns all clocks described in the DT, which are

Add support for selecting between continuous and non-continuous MIPI clock
mode.
Previously, the CSI-2 non-continuous clock endpoint flag was ignored and
the sensor was always configured for non-continuous clock mode. For
existing device tree nodes that do not have this property enabled, this
update will therefore change the actual clock mode.

The sensor supports an input clock in the range of 6 to 27 MHz. Currently,
the driver only supports a 19.2 MHz clock. Extend the driver so that at
least 24 MHz, which is a typical frequency for this sensor, can also be

The current settings for the "image vertical start" register appear to be
incorrect. While this only results in an incorrect start line for native
modes, this faulty setting causes actual problems in binning mode. At least
on an i.MX8MP test system, only corrupted frames could be received.
To correct this, the recommended settings from the reference register sets
are used for all modes. Since this shifts the start by one line, the Bayer
pattern also changes, which has also been corrected.
